5 New Year's Resolutions to Help Wildlife

 5 New Year's Resolutions to Help Wildlife

Twas the Day Before Zoo-mas

 Twas the Day Before Zoo-mas

Twas the day before Zoo-mas when all through the Zoo
Not a creature was stirring, not even a milky eagle owl named Rwe.
The target poles were placed in their drawer with care,
While the chinchillas rolled in dust to clean their hair.

The ferrets were nestled all snug in their burrow
While the care team made sure our records were thorough.
And Sean in his khakis tried not to make a peep
As the animals settled down for a nice winter’s sleep.

When out in the mews Rob heard a loud clatter,
Turns out Obsidian the black vulture was the source of the chatter
Then away to Wieland we flew like a flash,
Tore open the fridge and enjoyed our lunch stash!

The sun shone high on this crisp winter day
Which was perfect for alpacas rolling around in their hay.
When what to my wondering eyes should appear,
But goats and sheep and pigs to spread some holiday cheer.

With Sarah and Kaileen, so lively and quick,
It was time to clean with shovels, and rakes, and broomsticks.
Blake knew bringing goats and sheep inside could be quite a game,
So they whistled and shouted and called them by name:

“Now Wasabi! Now Barbie!
Now, Haku and Ponyo!
On Ella! On, Avocado!
On, Carmen, Cruz, and Shiro!
To the night yard!
To the inside stalls!
Now come inside, come inside!
Come inside all!”

As dry leaves that before from trees did fall
The care team used as bedding for all.
Southern toads blended in thanks to good coloration
Right after Roxanne and Rachael trained them to station.

And then, in a twinkling, I heard a small crunch
Of Cortez the macaw eating his lunch.
Nas moved through the building at a brisk walk,
When Sydney the cockatoo let out a loud squawk.

We were dressed in our navy and khakis and sneakers,
And played our holiday music loudly through speakers.
A bundle of treats Caroline placed in her pocket,
And she turned on twinkling lights for enrichment into a socket.

He moved through his home with a shell nice and strong
Cardboard the box turtle didn’t mind if we sang him a song.
He tore through a box full of dinner with such ease
Abby the northern ground hornbill was easy to please.

With a hard shell to cover their bodies and backs
Armadillos sat in the open to enjoy an apple snack.
The leaves of lettuce they held in their teeth
The rabbits encircled their bowl of dinner like a wreath.
A few nice windows for guests to see
Reuben the Patagonian mara sitting under his tree.

As the day’s end drew to a chilly close,
McKenzie said goodnight to the red-tailed hawk Rose.
Diets were prepared and fed out just right
So nocturnal mammals could forage at night!

I watched Indi the indigo snake glide under the soil
As the ball pythons curled their bodies into a perfect coil.
And finally the care team checked habitat locks
So we could go home and put on fuzzy socks.

We sprang to our cars, to our team we said goodnight,
And away we all drove on the last legs of sunlight.
But we heard James exclaim, as he too drove out of sight,
“Happy Zoo-mas to all, and to all a good night!”

Visit the Zoo Day

Presumably whoever instituted this holiday and selected this date lives somewhere in the southern hemisphere... that being said, depending on where you are in the United States or (especially) Europe (where there seems to be a much stronger emphasis on indoor exhibits), there's no reason that December 27th can't be a perfectly lovely day to go to the zoo.

Kids are still out of school and in need of things to do on winter break.  Crowds will be down.  Some animals are at their best in the cold - polar bears, Amur tigers and leopards, wolves, bison, red pandas.  Waterfowl are in their most spectacular breeding plumage.  Some tropical animals will surprise you with how cold hardy they can be.  Indoor exhibits can be especially appealing - nothing like taking a walk through a tropical rainforest, or walking through a coral reef, when there's snow and sleet outside.

The best way to make the most of winter zoo or aquarium visits is to buy a membership, so you can visit year-round on impulse.  On cold days or rainy days (or cold, rainy days), you can swing by for just an hour or so to hit your favorite winter-exhibits and then be on your way.

Merry Christmas!

 Hoping that everyone had a Merry Christmas, and made appropriate gift-giving decisions!

Reindeer Replacements

 

Species Fact Profile: Brazilian Agouti (Dasyprocta leporina)

                                                             Brazilian (Red-Rumped) Agouti

                                                        Dasyprocta leporina (Linnaeus, 1758)

Range: Northeastern South America – French Guiana, Guyana, Suriname, portions of Venezuela, Colombia, and Brazil.  Also native to Trinidad and Tobago.  

Habitat: Tropical Forest (Primary and Secondary), Scrubland, Wet Savannahs.

Diet: Nuts, Seeds, Fruits, Roots, and Leaves

Social Grouping: Pairs, sometimes accompanied by offspring

Reproduction: Pairs are monogamous, probably for life, and are capable of breeding year round.  Courtship consists of the male spraying the female with urine repeatedly.   Females give birth to 1-4 young after a gestation of about 120 days.  Young are born fully-furred with their eyes open and are capable of running within an hour of birth.  Young are capable of feeding themselves shortly after birth, but may nurse for up to 20 weeks.  Mature at 6 months, both males and females in zoos have been documented as breeding at under one year of age, though usually they start later than that

Lifespan: 8-12 Years (Wild), 15-20 Years (Zoo)

      Conservation Status: IUCN Least Concern

• Body length 49-64 centimeters, tail length 6 centimeters.  Weigh 3-6 kilograms.  Females typically larger than males.  The ears are small and rounded, the legs are long and thin.  There are four toes on each of the front feet, but only three toes on the back feet, terminating in hoof-like claws, which enable them to run quickly.
• Coarse, glossy fur is greenish-brown, red or orange on the backside (this species is also known as the red-rumped or golden-rumped agouti), orange-brown underside with a whitish stripe running down the center
•  They will follow troops of monkeys through the forest, feeding on pieces of fruit that they drop.    Will opportunistically eat insect larva
•  Especially well known for eating Brazil nuts, burying the nuts to dig up later when food is scarce.  They are important seed dispersers, being one of the only animals in their habitat that can crack open the shells of the Brazil nut, which may rely heavily upon agoutis for seed dispersal
• Dig burrows along riverbanks or among boulders and tree roots.  Maintain several shelters in their range, such as hollow logs and caves, with well-defined pathways linking their burrows.  Often found near water and are excellent swimmers.  Can jump almost 2 meters vertically.
• Usually sleep and feed alone, but they may forage together to keep watch for danger, warning one another with distress calls (resembles the barking of a small dog) and foot stamping
• Predators include jaguars, pumas, ocelots, snakes, and raptorial birds.  Primarily diurnal, but have become nocturnal in areas where they are heavily hunted by humans
• Genus name translates to “Furry Rump.”  Species name translate to “Resembling a Hare”
• Overall population is stable, but some populations may be in decline due to heavy hunting for food.  As long as there is sufficient cover to hide in, populations are able to persist even in disturbed habitats.  Sometimes hunted as an agricultural pest
• They have been introduced to Dominica, Grenada, and the US Virgin Islands

AI: The Zookeeping Fronteir

 "I've come up with a set of rules that describe our reactions to technologies:  1.) Anything that is in the world when you're born is just a natural part of the way the world works.  2.) Anything that's invented between when you're fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.  3.) Anything invented after you're thirty-five is against the natural order of things."

- Douglas Adams

Oh, if Adams had lived to see AI in its present form.  He speculated a lot about it in his books, but here it is now.  It seems like every week we're getting another news article about how the technology will impact us, with some people saying we'll be in paradise and never half to work again, and the other half saying that 85% of us will be laid off and die in the streets.  So, the usual tech forecasts.  

Zookeeping, presumably, will be one of those fields less directly-impacted by AI, but the technology is still making its impact felt on the profession.  People use AI to record and summarize meetings.  Vets use AI to write their preliminary charts and record their rounds.  Despite some scowling, office folks are using it to generate materials for marketing, education, etc.  I could envision a future where registrars use AI to process permits and records, vets feed data through AI for diagnoses, and education produces AI talks and presentations.  But actually working with the animals?  I don't see that being switched to AI.

Personally, I'm not a fan of the tech.  I feel like it's not only bad for the environment (using an amazing amount of energy and water) and bad for employment, but also generally contributing to the loss of skills and the overall dumbing-down of mankind.  To say nothing of the spread of false information, which is going to only make it harder to identify and correct as it gets more sophisticated. It's nice to think at least our corner of the workforce will remain less-impacted... or so I hope.

Animal AI: A Warning

 The Reality of AI Animal Content

Santa vs the Sea Turtle

It's hard to believe that it's only one week until Christmas, and then, after that, only one week until 2026!  Still, a week is plenty of time for Santa to decide which animals belong on the nice list and which ones on the naughty... and Old Green, a sea turtle from Adventure Aquarium, is making it pretty clear which list she belongs on!

'Tis the Season

The Holidays can be a merry time of year for many.  They can also be extremely stressful.  From a zoo perspective, I tend to feel the later more than the former.

Especially those last two weeks of December (where we find ourselves at the present) and into early January, you start to find yourself increasingly short-staffed, as folks go visiting out of town, or have to entertain visitors from out of town, or parent keepers have to take time off to care for kids that would normally be in school.  The keepers that are still in may be stressed or distracted by holiday plans (and holiday bills), or maybe gloomy and homesick.  Their minds may be wandering.

Oh, and it's also that time of year when everyone starts of get sick.

Meanwhile, depending on a number of factors - your zoo's location/nature (indoor aquarium vs outdoor zoo in the north), whether your open or closed or not at that time of year - you may be surprisingly busy, again with kids out of school and folks visiting from out of town.  The basic work of the zoo - caring for the animals - does not slow down that much in the winter.  Animals can't be put in storage due to staffing issues, and still need to be fed and cleaned.  Extra points if your zoo also decides to have some holiday events and ropes you into helping with them.   

Oh, and it's also that time of year when the northern hemisphere experiences winter, which can mean you might be dealing with all sorts of weather emergencies, medical issues, and other seasonal delights.  And then you're faced with an issue, and surprise, you're down a vet because one went out for the holidays, or you need to make a decision about something, fast, but everyone who needs to make a decision is away.

Dealing with all of these stressors against the forced-cheerfulness of holiday lights and canned Christmas music, and there are times when you may think Scrooge was too charitable in his feelings about the season.  It's for this reason that I've often thought many working folks would benefit from having their own holiday to celebrate and relax... after the Christmas season.

Zoo Review Updates, 2025 - Part II

The Maryland Zoo in Baltimore broke ground on a new habitat for red pandas, the first project in the planned renovation of the zoo's historic Main Valley.  The exhibit is slated to be opened next year as part of the celebration of the zoo's 150th anniversary.

Milwaukee County Zoo just completed the last step in its ambitious Adventure Africa project to renovate its pachyderm exhibits with a new indoor/outdoor habitat for black rhinos.  The zoo also announced an exciting new masterplan which will see many new projects, including renovation of the reptile house/aquarium and a new Central American rainforest exhibit.  As part of the renovation process, the old Small Mammal House has been shuttered.

Nashville Zoo opened its new Leopard Forest, featuring Amur leopards (as a stand-in for the African subspecies) with side exhibits of klipspringer antelope and colobus and DeBrazza's monkeys. Guests can see the cats for various viewpoints, including from below as the leopards use an elevated bridge to pass from enclosure to enclosure.  Compared to other big cats, leopards are seldom highlighted in major exhibits, so this new exhibit is a real treat.  Next year, the zoo will be breaking ground on a two-story orangutan habitat, the anchor for a Southeast Asian exhibit that will also feature langurs, birds of paradise, tree kangaroos, otters, and a new habitat for Nashville's iconic clouded leopards.

Slowly but surely, the development of Asia is underway at the North Carolina Zoo, with animals already trickling in.  The exhibit complex is supposed to open next year - and then on to Australia!

Oglebay's Good Zoo will be adding a lion exhibit, having broken ground this year for an anticipated opening in 2026.

The Philadelphia Zoo opened a new aviary habitat for greater flamingos.  Construction on the renovated bear habitats also continues.

Phoenix Zoo opened its new habitats for Big Cats of Arizona, featuring jaguar and puma.

The Pittsburgh Zoo and Aquarium is kicking off its masterplan with the first project, a state-of-the-art new barn for giraffes, which will feature indoor and outdoor viewing of the world's tallest mammals.

Potawatomi Zoo is expanding by two acres, using the new land for Big Cat Tracks, which will provide new habitats for Amur tigers and Amur leopards, as well as Asian deer and cranes.

San Diego Zoo Safari Park opened Elephant Valley, a renovated home for its African elephants.

Tulsa Zoo opened its expanded new Asian elephant habitat.  Construction is in progress for the new African area, which will see new habitats for lions and African wild dogs, as well as the return of zebras and the Zoo's first pygmy hippos.

WCS Bronx Zoo reopened its World of Darkness after being closed for almost twenty years.  The building features aye-aye, bats, caiman, and more!  Nocturnal houses are something of a rarity in zoos these days, so the opening of a new (well, returning) nocturnal building is a big deal, especially when it's from a facility that excels in exhibitry like the Bronx does.

Woodland Park Zoo opened Reptile Realm, featuring its Komodo dragons as well as a small handful of other southeast Asian herps, such as Philippine sailfin lizards and giant forest tortoises.  It's a pretty tiny reptile collection, but considering how small Seattle's reptile collection was to begin with, it's a pretty dramatic increase and a definite improvement in the collection!

And, lastly, some of the most eagerly anticipated US zoo news of the year, giant pandas are once again on display at the Smithsonian National Zoo!

Zoo Review Updates, 2025 - Part I

Akron Zoo is in the midst of a renovation of its Legends of the Wild area.  Some species are being phased out, some new species brought in, and other habitats being reimagined for the species that they currently hold.  I'm not sure if the theme will be the same, or if it will be redone as a zoogeographic area.  The next new construction will be an expansion of the African area, which will bring giraffes to the zoo.

Aquarium of Niagara has expanded its campus with Great Lakes 360, a new building that highlights the fish, herps, and inverts of the region.

Arizona Sonora Desert Museum has announced plans for an expansive new habitat for its Mexican wolf pack.  There had been some suggestions in recent years that the Museum had been overlooking/reprioritizing away from the zoological aspects of its collection, so this project is a very welcome one!

Chicago's Brookfield Zoo completed the massive outdoor annex to its iconic Tropic World building, giving outdoor access to gorillas, orangutans, and South American monkeys, as well as adding an additional indoor gorilla habitat.  The koalas that were on loan to the zoo have since left, but the species is expected to return as part of the highly ambitious masterplan.  The old Pachyderm House is shuttered as a first step towards the construction of the new African area.

Cincinnati Zoo celebrated its 150th anniversary with a renovation of the old bear grottos into larger, more natural habitats for American black bears and, a new addition to the zoo, sea otters.

Clearwater Marine Aquarium has a new manatee exhibit, joining the Florida institutions that are rehabilitating and exhibiting these giant aquatic herbivores.

Cleveland Metroparks Zoo continues work on turning the Rainforest building into a new Primate Forest (which is not to say that non-primate residents, such as the gharials, will not be returning).  The orangutans will have outdoor access, and the gorillas will move down here from their current home in the Primate, Cat, Aquatics building.

Phase I of the North America renovation at the Columbus Zoo and Aquarium is complete.  Mexican wolves, American black bears, North American river otters, and bald eagles are featured, along with trumpeter swans and a recreation of one of the zoo's most unique exhibits, the North American songbird aviary.  There is also an indoor exhibit space to highlight the zoo's local conservation commitment to species such as hellbenders.  Phase II will see the renovation of the habitats of wolverines, Canada lynx, caribou, moose, and sandhill cranes.

Detroit Zoo is preparing to unveil its Discovery Trails, a new children zoo.  Besides the expected domestics, the trail will feature a stingray touch pool, prairie dogs, giant anteaters, and, a bonus for zoo enthusiasts, rarely-exhibit bush dogs.

The new Aldabra tortoise exhibit has opened at the Indianapolis Zoo.

Los Angeles Zoo has sent their two Asian elephants, Billy and Tina, to the Tulsa Zoo, leaving an enormous, empty habitat in the heart of the facility.  What will become of this space - and whether elephants will return to the zoo in the future - is not yet known.  On a more positive note, the zoo opened it's long-awaited (and quite excellent) new aviary for Cape vultures.

We'll look at more zoo updates tomorrow!

Shocking Around the Christmas Tree

Merry Christmas from the Tennessee Aquarium with their electric eel-powered Christmas tree lights!

The Odds (and Rocks) are Stacked Against Hellbenders

Earlier this year, rangers at Great Smoky Mountains National Park, which straddles North Carolina and Tennessee, reported finding a hellbender which had been killed by a fallen rock.  This animal's death wasn't exactly natural causes, though - the rock which had crushed it was part of a stack made by park visitors in a stream, for... reasons?  The Park responded by issuing a statement/making social media posts requesting visitors not do such things in the future.

I very much doubt that the people who made the rock stack intended any harm.  I like to think that, if they knew what would happen, they wouldn't have done it.  People do stuff like this all the time as a sort of self-expression or creativity, a way of saying "I was here," and there are ways to do that that are safe and fun and creative.  This just ended up not being one of those things.  It's understandable that this wasn't on everyone's radar, but now that it is, it should be a "Well, now we know, let's not do that" lesson.

What blows my mind is the response from so much of the public.  Claims that its their God-given right to stack rocks.  Refusal to believe that it matters at all - since rocks move naturally in, say, storms or floods, and we can't control that, there's no harm in stacking rocks ourselves.  Refusal to believe that hellbenders are actually rare ("We see them all the time, everywhere, we just call them mudpuppies" - nope, different animal.  Also not okay to crush less-endangered animals with rocks).

I think of all the zoos working so hard to restore hellbenders to the wild, just to loose them because someone wants to make a cool rockstack for an instragram post (yeah, I wish I could convince myself that this was just kids playing).

The infuriating truth is that so many people take immediate umbrage to even the kindest of suggestions that they do something slightly differently, like "How dare you tell me what to do, you're not the boss of me!"  The saga of the squashed hellbender reminds me of a saying that I heard long ago.  We know what needs to happen to save virtually every species from extinction.  We know how to do it.  The problem is, most of it involves changing human behavior - and that's something we've never figured out how to do.

Book Review: The Book of Wilding - A Practical Guide to Rewilding, Big and Small

"A wilder, more resilient world is within our reach."

As the year winds down and January approaches, many people begin to look ahead and think of their New Year's Resolutions.  Resolutions are all about doing better - for yourself, for your friends and family, for your community.  This year, why not consider expanding your circle to include the whole planet?

At first glance, The Book of Wilding: A Practical Guide to Rewilding, Big and Small might look more like a textbook than a light read.  The hefty tome, written by Isabella Tree and Charlie Burrell, focuses on the art and science of modifying our human-dominated landscapes to create a more sustainable world for wildlife.  The book's central example is an ancient family farm that Burrell inherited years ago, poorly suited and unprofitable for farming after years of unsustainable practices.  Instead of giving up, the authors worked to rehabilitate the land to create a nature reserve, a slice of Ancient Britain.

When rewilding is discussed in the press, the focus is largely on the reintroduction of large carnivores, such as wolves, some of which may have been absent from a landscape for centuries.  This book acknowledges that such events are unlikely, distant-horizon projects, and instead focuses on smaller-scale, more sustainable rehabilitation efforts.  Emphasis on large animals is largely limited to herbivores - both long-absent large herbivores as well as proxies for extinct species - which the authors see as the landscape engineers which shape habitats both in their lives and their deaths.  While much of their book is focused on larger landscapes, such as farms and urban parks, there is also a chapter on the smallest-scale of rewilding, our own backyard plots.  (The book is well-organized in such a way that you can easily skip over parts that aren't relevant to your case and move ahead to sections that are).

Also, whereas many critics of rewilding sense a distinctly misanthropic streak in the concept ("Four legs good, two legs bad, humans out of everywhere), this book strongly acknowledges the realities that humans need places to live, work, and raise food, and we're not going anywhere.  The emphasis of the book is on finding ways for all species - including our own - to coexist and thrive together.  So much of what is bad for the natural world, it is pointed out, really isn't that great for us either.  Likewise, many people seem to think that rewilding is about going back to a set point in time, a pre-human age where everything was perfect, and then freezing it there.  The authors disagree with the notion, noting that natural landscapes are always in flux, and there is no perfect past postcard that we should be trying to recreate; that's in part why they call their work The Book of Wildling, not Rewilding.  

Written in the aftermath of COVID-19, the book highlights how isolated so many of us have become from the natural world, and much we benefit from connection with wild spaces.  In improving the world for wildlife on any scale, we improve it for ourselves.

Keeping with Crab Cakes

There was a recent conference - one that I didn't go to, but I was talking to someone who did attend.  They mentioned a comment made by one of the presenters that stuck with them: "Don't do for the animals that which the animals can do for themselves."  It was a very simple statement, but it did seem to sum up an excellent point about animal care.

Some keepers and curators have a tendency to want to baby their animals, swaddle them up and do everything for them, with the feeling that this represents optimal care.  It can make life easy for the animal... but in a zoo setting, easy is the kissing-cousin of boring.  Life for a wild animal isn't easy.  There's challenge and struggle.  Some of that we can't - and arguably shouldn't - be recreating in a zoo.  But by doing everything for the animal, we deprive the animal of opportunities to fully utilize the body and brain like they would in a natural setting.

Suppose you and a friend went to a seafood restaurant.  You order a crab cake.  Your friend orders a few steamed crabs.  The food comes out, and your friend is picking up the crabs, examining them.  Maybe it's a food item they don't eat too often.  They have to figure out how best to open the crab, then crack the shell and tediously pick out the meat.  It's a process that takes quite a while.  You, on the other hand, have finished your crab cake in less than a minute.  Your meal has taken a fraction of the time and zero of the thought and effort compared to your dining companion's experience.

It goes beyond feeding.  Some keepers I know pre-make nests for their birds to encourage them to breed, when in reality, the act of selecting a site, choosing the materials, and actually building the nest is an important part of courtship for many birds.  You could churn up a mud wallow or dust bathing site for some of your ungulates, or let them make their own.  

Just think back to when you were a small child, and you first started picking out your own clothes to wear, or got a knife and fork at the dinner table, so you could cut up your own food, rather than have an adult do it for you.  For a child, it's an empowering experience, one that makes them feel a little more grownup, even if they can't do the job as well as the grownup can.  The more opportunities you give the animals to do things for themselves and make their own choices, the more in control of their lives they will feel. the more natural behaviors they will be able to express.

To misquote John F. Kennedy, ask not what you can do for your animals.  Ask what your animals can do for themselves.*

*The caveat is, of course, to be mindful of when the animal can't do things for itself.  If you went to the seafood restaurant and your friend had an arm in a cast... maybe then the crab cake is the better option.

Snacking for Two

The Denver Zoo's tamandua, Winnie, is expecting!  The zoo highlighted the upcoming birth by showing off Winnie getting her ultrasound, with complimentary snacks for the mom-to-be!  95% of the comments on social media are some variation of women asking, "Why didn't I get snacks during mine?" - a fair question, to be sure.  And don't mom and dad look so proud of themselves, too?

Species Fact Profile: Malayan Flying Fox (Pteropus vampyrus)

                                               Malayan, or Large, Flying Fox

                                               Pteropus vampyrus (Linnaeus, 1758)

Range: Southeast Asia (Vietnam, Myanmar, Malayan Peninsula), Indonesia (Sumatra, Java, Borneo, Timor, and adjacent small islands), Philippines

Habitat: Tropical Rainforest, Mangrove Forest

Diet: Flowers, Nectar, Fruit

Social Grouping: Small groups of one male and several females and their young, but may congregate in colonies of 10,000-20,000 animals

Reproduction: Gestation period 180 days.  Births primarily occur between March and April, with seasonality varying somewhat across the range.  Usually give birth to single offspring, born fully-furred, with eyes open, and already 1/3 the size of the mother.  Young bats are nursed with two nipples near the armpits, cradled by the mother with her wings.  Males do not assist with rearing the young.  The young carried by the mother for the first few days, then left at the roost while the mother goes to forage.  Young are weaned at 2-3 months old

Lifespan: 15 Years (Wild), 30 Years (Zoo)

      Conservation Status: IUCN Near Threatened, CITES Appendix II

• One of the world’s largest (possibly the largest) living bat species.  Head-to-body length 27-32 centimeters.  Wingspan of 1.5 meters, forearm length 18-22 centimeters, body mass 0.6-1.1 kilograms.  Long, pointed ears and dog- or fox-like face and head.   Wings are short, rounded on the tips, allowing them to fly slowly, but with great maneuverability.  Males are slightly larger than the females
• The head and upper body in adults are covered with a dark mantle, color ranging from red to black, turning gold or orange in the males during the breeding season.  Remainder of fur is brown or black with a scattering of white hairs.  Juveniles are almost uniformly dull gray-brown.  Fur is longest on the mantle.  Males tend to have thicker, stiffer fur than females, as well as neck tufts.  Wing membranes are only haired near the body
• May fly up to 50 kilometers in a single night while foraging.  Circle trees in the air before landing – usually land on the branch tips in an upright position, then drop into an upside-down position to feed.  They do not echolocate, instead relying on sight and smell to find fruit.  
• Capable of eating half of their body weight daily.  Likely to be important pollinators and seed-dispersers for many trees within their range, as they are one of the few frugivores large enough and mobile enough to transport seeds and pollen considerable distances throughout the forest
• May drink seawater to obtain salt, other minerals absent from their very sugary diets
• Capable swimmers, using their wings as flippers; sometimes seen crossing rivers.  May fly across short spans of ocean to feed on nearby islands.  
• Spend much of the day hanging upside down from branches (especially from emergent trees) with its wings wrapped around the body, often restless until mid-morning.  If the bat becomes too warm, it will unwrap itself and fan itself using its wings    
• A natural reservoir of the Nipah virus, which has crossed over into (potentially fatal) humans and pigs.  Captives maintained in research labs have tested negative for the antibodies against the virus for several months before testing positive again, suggesting that the virus can maintain itself in flying foxes after periods of remission
• Genus name Pteropus translates to “wing foot.”  Species name is in reference to vampires, though this species does not feed on blood
• Seven subspecies recognized, sometimes each listed as a separate species;  the most threatened is P. v. lanensis, of the Philippines
• Primary threat is loss of habitat due to deforestation.  Hunted for bushmeat in parts of their range, such as Peninsular Malaysia, unlikely to be sustainable (hunting has more the doubled in recent years).  Some cultures believe that their meat has curative or medicinal properties, can treat asthma.  Most effective protection strategy so far appears to be protecting colonies on small, easy-to-monitor islands. Also persecuted by farmers who consider them agricultural pests.  Some farmers may use flapping or whirring devices, bright lights to discourage them from feeding on their crops

From the News: Man Killed by Lion After Breaking Into Zoo Enclosure

Man Killed by Lion After Breaking Into Zoo Enclosure

A 19-year old Brazilian man with a deep love of animals and a history of mental issues was killed this week after he deliberately climbed into the lion exhibit at the Arruda Camara Zoo Botanical Park.  During public hours, in front of a crowd that begged him to stop, Gerson de Melo Machado climbed a fence, then lowered himself into the exhibit, where a lion was watching and waiting.  The video of the incident is out there, but I've opted not to share it here.

It's difficult to say if this was a suicide, or if the young man was expecting a different outcome.  He previously had been caught trying to smuggle himself onto a plane to Africa so that he could be among animals.

My deepest sympathies to the family and friends of Machado, as well as all of the zoo goers and staff who had to witness this tragedy.  The zoo has confirmed that the lion, which, of course, was behaving as one would expect of a lion, is safe and unharmed, and euthanasia was never considered.

Building a zoo exhibit that keeps animals in is, in all reality, not that difficult.  Building one that prevents casual, accidental entry by humans is also feasible, though mistakes do happen, especially when barriers are reduced to improve accessibility of the exhibit and viewing of animals; think a child getting dropped by mistake into an open-moated enclosure.  But building an exhibit that prevents any possible access by a very determined person who wants to get in/access the animal no matter what?  That's a lot trickier, probably only possible if every exhibit is completely enclosed in glass or acrylic.

The zoo remains temporarily closed while a security review is carried out.

A Rainy Day

The older I get - and especially the longer I worked in zoos as a keeper - the more that I came to hate rainy days.  I don't like being cold and wet, and the rain, especially the heavy storms, made such a mess, and literally made everything harder and worse.  Well, almost everything.

If there's one thing I came to appreciate about rain, it was the cleaning powers.  Yes, I know I also just said that the rain makes a mess, and it does, especially when drains clog up and things start to flood.  But one thing rain does especially well is clean things that are hard to reach and hard to scrub off.  I'm especially thinking of perching in some of our larger bird exhibits.

Every once in a while, a fit of ambition would hit me, and I'd laboriously haul a ladder from aviary to aviary, haul in a big bucket of warm soapy water and a scrub brush, and then spend the day either trying to bring the bucket up the ladder with me, spilling half of it in the process, or make countless trips up and down.  This would be all in the name of scrubbing off the bird droppings... but usually it just ended up looking white and smeary.  Now, a good, slow, steady soaking rain, on the other hand, can really clear things off... without me having to do much.

I sometimes wonder if custodial staff feel that way about some of the stains around zoo grounds in the public areas.

Rain also other benefits for the animals, in moderation.  It's enriching, changing the environment, creating new mini-water features for animals to bathe in, changing the smell and feel of the exhibit.  It can let birds preen their feathers and get themselves clean.  Even just forcing the animal to make a decision about whether it wants to be out in the wet or dry under shelter (and the animals should all have the freedom to make that decision) is empowering for them.  For that reason, some indoor zoo exhibits, especially rainforest buildings, also give their animals mock rainstorms.

But from an employee perspective, all I can say is, at least it gets some of the tough stains up.
