From China, with cuteness

In recent months, the zoo has welcomed a small batch of unusual warm-blooded fur-babies, including a binturong, or bearcat, not yet on exhibit and a tapir, now nine months old and looking like a smaller, feistier adult. But the latest one, a takin born Feb. 4, is the current show-stopper, especially since she went on public view after just three weeks and likes to do cute things like scamper around the exhibit, attempt to mountain-climb her dad’s belly while he’s trying to nap, and nuzzle her mom’s face.

The second time I saw her, last week, she was more than a month old and cavorting in a light snowfall (and yes, as we see here, nuzzling). Sichuan takins — it’s pronounced TAH-kin — are related to the mountain goat and musk ox. Adults weigh about 600 pounds on average. This little one’s name, I learned at last weekend’s volunteer update seminar, is Bing Leng, which fits the species’ Chinese heritage. Sichuan takins, the most common variety in zoos, hail from the country’s forested mountains. Like the giant panda, takins have been declared a national treasure worthy of protection in China, and the two species share an overlapping habitat in the wild. As large animals that live in herds at high elevations, they have few predators, but hunting and habitat loss mean they’re classified as threatened — a step down from endangered. In human care, they can live up to 20 years.

Bing Leng has been exploring the exhibit, and testing her climbing skills, under the supervision of her parents and a fourth, female takin named Mu Shi, who’s -a 3-year-old recent arrival from San Diego with breeding prospects of her own. Bing Leng’s transformation will continue as her hair lightens in the next few weeks and she starts sprouting horns at six months. As spring arrives on the Northern Trail, it will be increasingly fun to watch.

 

 

 

 

Dragon days

Hello again! I’m back here blogging after a long break, inspired partly by a new year but especially by some of the zoo encounters I had at the end of the old one. In 2015, Christmas and New Year’s Eve both fell on Thursdays, my weekly volunteer day. And both days brought a remarkable batch of families to the zoo — inquisitive kids with parents who encouraged them to linger and ask me questions, or who saw me with an artifact and pulled their kids over to take a look. As one dad said to his son, “Here — come learn something.”

If I want to pack a lot of facts into one half-hour session, I stand by the Komodo dragon exhibit and hold the Komodo-jaw artifact. Since the passing of an elderly Komodo monitor named Gasher, who received acupuncture treatments to ease his arthritis, the exhibit’s sole occupant has been this young guy, whose name I don’t know yet. (The Komodo is one of those animals that doesn’t necessarily have a “public” name, but when you attend volunteer update seminars, you learn what zookeepers call them.)

How can I tell this guy is young? Aside from his relative smallness (a male Komodo can get up to 200 pounds and 7 feet long), he still has a blush of color on his scales, and he still climbs the big log in the middle of his exhibit. Baby Komodos climb trees soon after they hatch and stay up there for several years, evading hungry predators — including their own parents. Since they’re highly endangered, with a native habitat restricted to the Indonesian islands, feasting on their own offspring is not the smartest survival strategy for the world’s largest living lizards. (In terms of interesting facts that are also kind of alarming and scary, Komodos win hands-down. I’ve learned out to leave out details like that one when I’m talking to smaller or more sensitive-looking kids.)

When I’m standing by the exhibit holding the jawbone artifact , I show kids how a Komodo, like its reptilian cousin the snake, can unhinge its jaw to swallow a small animal whole or take big sloppy bites of a much larger animal — possibly even a water buffalo. Komodos can eat 80 percent of their body weight in a single meal — keeping in mind, of course, that for these and other predators, there’s no guarantee of a meal every day in the wild. At the zoo, they’re fed various meats including chicken and quail — and live in a warm, safe, tropical space where nobody (resident or visitor) gets eaten at all.

 

 

 

 

Summer of the seals

Even with the memory of the dolphins still fresh in our minds, everyone at the zoo was at least a little excited when the zoo’s Hawaiian monk seal exhibit opened a few months ago, bringing the old dolphin pool back to life. Sure, the seals could never live up to the dolphins — what could? — but especially for volunteers stationed an hour or two each week in Discovery Bay, any life in that pool was welcome when it finally reopened after months of renovation. My expectations honestly weren’t that high. At least the seals would be interesting to talk about, if not as interesting to watch.

But now that their summer honeymoon period is over, I know that the seals are, in fact, both things — factually and visually engaging enough to help me reboot this blog after six months of dormancy. No matter how distracting life gets, I always gravitate back to the zoo. And zoo visitors have gravitated to the seals, with their torpedo-shaped bodies, powerful flippers and heavily whiskered faces. In a typical response, one woman exclaimed last week: “It’s so cute! It looks like a little old man!”

Hawaiian monk seal and zoo visitors

All five monk seals, which came to us via a facility in Texas, are female, 400-500 pounds and about 20 years old. All but one have limited vision, all were originally rescued as starving pups off the coast of Hawaii, and none could survive in the wild today. Unlike dolphins, the seals like to “haul out” of the water and rest, and their redesigned zoo habitat has small stretches of “beach” for that purpose. When they wriggle awkwardly onto “land” to during public feedings, a soft “aww” or fond giggle often rises from the audience.

At first, I didn’t think I’d memorize the five names, which are all short, similar, Hawaiian and full of vowels. With limited brain-space, a docent learns to prioritize, and only the most basic or compelling information — usually about the species, not the individual — joins the long-term memory bank. The seals look identical at first glance, anyway, and don’t interact with each other, since the species (unlike harbor seals) is naturally solitary. But it quickly became clear, week after week, that guests wanted to know the names, and also that the seals weren’t identical at all.

Ola the seal twirling

So far there are only two seals in the show pool at once (again, because they’re not very social — which is fine!). On my Thursdays so far, those two usually seem to be Ola, who has good vision and swims laps with a playful, twirling motion (I think that’s her above), and Koa, below, who doesn’t see well and floats vertically next to the glass. Often she seems to be watching the big TV screen for seal-related images and information. This cracks me up. In reality, she may be listening more than watching — seals have very good hearing, although they have no external ear flaps as sea lions do. This makes even our sight-impaired seals very trainable; they listen for their names and other cues. (The other seal duo that rotates in and out of the show pool is Paki and Opua. The fifth seal, Nani, has been happily hanging out by herself in the “west pool” so far.)

Koa the monk seal

There’s so much more to say about Hawaiian monk seals, and in months to come, I plan to say it. For now, it’s enough to note that these whiskery marine mammals aren’t just a post-dolphin placeholder. They’re fascinating in their own right.

Sensitive spooning

Eleven years into volunteering at the zoo, I’ve noticed that I go through favorite-critter phases, with a “best thing at the zoo right now” orientation. Because the South American aviary on the Tropics trail was a new addition last fall, with its waterfall and its chorus of chirping, and because that leafy green trail is such a refuge in winter, that’s my “best thing” this season. And my favorite bird in that aviary is the roseate spoonbill, which the Audubon Society accurately describes as “gorgeous at a distance and bizarre up close.”

Standing about 30 inches, the spoonbill is related to a flamingo and looks like one, too — until you notice the bill. In this aviary, that’s not always easy to do, because our two spoonbills — like their other on-exhibit relatives, the scarlet ibis — like to perch in the treetops, beak tucked under wing. But first thing in the morning, one spoonbill likes to pace the lower level, brushing the ground with that amazing implement on his face. (On the day I took all these photos, zookeeper Ben told me this one is the male and has a slight wing injury from some mysterious phase of his pre-Minnesota life. The roosting female would be a bit smaller-bodied, and smaller-billed.)

spoonbill scavengingThis big, odd, beautiful shore bird was behaving much as he would in the wild, where spoonbills sweep their heads from side to side in search of tasty morsels, especially in shallow water. The spoon-shaped bill is a sensitive instrument full of nerve endings, and when its owner scoops up a mouthful of water, that bill has the advantages of a sieve; it opens slightly, the water leaks out the sides and the tasty bits of seafood get swallowed, along with the occasional piece of plant life.

They’re in our South American exhibit for a reason, but roseate spoonbills can also be found along U.S. shores in Florida, Louisiana and Texas. In our zoo space, they coexist with several smaller species besides the ibis. My second-favorite bird species in this aviary, the black-necked stilts, were keeping anxiously clear of the much larger Mr. Spoonbill, who strode purposefully across every inch of the exhibit in the 20 minutes I spent hovering with my camera. Eventually he fluttered up to join his mate in the treetops, and I craned my neck for one last look before moving along.

Obituary for an octopus

She lived in Discovery Bay for six months beginning in May. I didn’t see a lot of her in the summer, even when I made special trips to that end of the zoo to check out this new attraction. She was probably hiding in her cave, something wild octopuses often do in the shallow seas they call home. But by fall — because I was scheduled to volunteer in D-Bay more often, because the crowds had died down or because she had just settled into her tank — she became the entertaining sure thing in that part of the zoo. There were always a few people gathered round the tank, and most of them wanted to linger and talk about her for more than just a minute or two.

Minnesota Zoo octopus posingBefore the octopus arrived, we had a series of cuttlefish in here — just another type of cephalopod (Greek for “head-footed”). So a lot of their cool facts applied to her, too: their ability to change color and squirt ink, their three hearts and blue blood, their excellent vision and poignantly short one- or two-year life span. Where the cuttlefish’s eight arms and two tentacles are clustered near the front of its head, though, the octopus has its arms farther back and a mantle — the sac that holds all its organs — in front of its face. Every part of an octopus is squishy except for its beak, which it uses for cracking open shellfish; combined with their high intelligence, this makes them good escape artists able to squeeze through small gaps. Male octopuses have one differently shaped arm — the “business arm” of reproduction, if you will — that this one apparently didn’t, sealing her identity as female. For either gender, reproduction marks the end of a life that’s extremely short anyway.

common octopus swimmingOctopuses swim differently from cuttlefish, too; there’s a lot more arm involvement, and those arms are covered with suction cups that make walking on the tank-side possible. This girl was a graceful and entertaining swimmer (though I could never decide whether she was doing the crawl or the breast-stroke) and an accomplished tank-walker, too.

So yes, I’m writing about her in the past tense. She’d been looking whiter in recent weeks, which worried a regular guest or two who’d been paying attention, though that may have been a coincidence. On Thursday, a week before Thanksgiving, the volunteers’ day began with a visit from aquarist Becky, who told us the octopus had died two days before, after “politely” refusing meals of shrimp for the previous week, and that the cause was definitely old age. The entertaining cephalopod came to us from the Mall of America’s aquarium, where she’d lived for four months. Wild-caught off the coast of Florida, she arrived full-grown in Minnesota and had to be at least 18 months old by now. Becky told us we’ll be getting a giant Pacific octopus by  late spring, in a new and larger tank, as part of a D-Bay makeover. That one will probably get twice as big as the common octopus we had (the Monterey Bay Aquarium says their Pacific is six feet across, “tentacle to tentacle”) and live twice as long, but I don’t think I could possibly enjoy it twice as much as I’ve enjoyed this dear departed one.

 

 

 

To the bat cave!

Meet Fang. He’s an Indian fruit bat, on view at the zoo’s Tropics trailhead throughout the spooky, creepy month we’re calling “Howlzooween,” and he’s a real kid-magnet. Without fail, kids approach the bat booth in fascination and ask the same two questions in rapid succession: “Is that real? Is it alive?” This might get old for the volunteers spending half-hour shifts at the booth this month, repeating “yes” (real) and “no” (artfully preserved), except that these questions are just our jumping-off point to share other bat facts. And there are plenty of those.

Fang the fruit bat at Minnesota Zoo

The world contains 1,300 species of bats, most varied in the tropics but scattered pretty much everywhere but Antarctica and the Arctic Circle. Our own Tropics trail is home to a cave of 90 fruit bats representing three species. Unlike Fang, all seven of Minnesota’s native bat species are insect-eaters — including the little brown bat, which can devour 150 mosquitoes in 15 minutes. When they’re not bug-hunting — or pollinating, as fruit bats do; who knew!? — bats prefer to hang upside-down in enclosed spaces like mines or caves. Two exceptions: If they’re giving birth or relieving themselves, bats can hang right side up by the “thumbs” on their wings. Northern bats either migrate or hibernate in winter, depending on their species. The hibernators, including the little brown bat, are increasingly at risk from white nose syndrome, which damages their wings and disrupts their hibernation, driving them out into the fatal cold in search of food and water.

Fang facing usOne of my fellow Thursday volunteers has a long-standing love of bats, so needless to say, this month’s focus has delighted her. While I’ve never feared this flying mammal, my regard is more intellectual and wary. But now that the zoo has taught me so much about them — and given me a chance to teach others — I’ve gained new respect for their place in the ecosystem, and concern for their future.

Bye bye, butterfly

It’s been a spectacular Sunday on the razor’s edge between summer and fall: brilliant blue sky, mid-70s, cool dry breeze, surely the last weekend day of its kind before the coats come out. On Labor Day morning last week, I took my husband to the zoo to say a seasonal farewell to its butterfly garden on the more official “last day of summer.” This morning, in my own mini-butterfly garden (modeled on the zoo’s), I saw a late-season monarch stop by, perching for a minute or two on a stalk of my joe-pye weed before it was on its way.

This is my joe-pye weed — a superb, hardy, pollinator-attracting plant I would not have tracked down for my yard if I hadn’t seen monarchs all over it a couple years back at the zoo. Just keep it watered, and it will spread on its own. That is not, of course, a monarch up there but an Eastern tiger swallowtail butterfly that hung out in my yard for two weeks straight in August. Last year I was a little sad that only bees were drawn to the tall plants — although this year at the zoo, as we focused on the importance of pollinators, I realized that bees need our help more than butterflies in that respect, with the added risk of colony collapse disorder and bees’ crucial role in providing not just honey, but essentials like chocolate and coffee as well, by spreading pollen from plant to plant as they sip nectar. This year, bees and the butterfly, which finally appeared in August, shared the joe-pye weed.

On Labor Day, the zoo’s butterfly garden’s last hurrah for the season, the most active and visible subspecies was this orange one, known as a julia.But even after that garden goes dark for nine months, the zoo keeps its hand in butterfly-conservation efforts — specifically, preserving the Dakota skipper and Powesheik skipperling, inhabitants of Minnesota’s ever-shrinking tall-grass prairie. (Skippers are a butterfly-moth hybrid explained here by the self-described Old Naturalist. And the key differences between butterflies and moths — butterflies have knobbier antennae and hold their wings closed while perching) are detailed here by the Lepidopterist’s Society.)

My tiger swallowtail (so reliably present for a couple of weeks that I dubbed it my “yard pet”) has moved on — either by migration or by virtue of a lifespan measured in weeks. There’s a sadness in the fleeting beauty, but still hope that careful perennial-planting choices can lure next year’s generation, too.
