It’s Definitely Summer at Oakland Zoo!

zena-the-zookeeperGreetings, fellow conservation heroes – Zena the Zookeeper here!

Glorioski it’s been hot lately! We zookeepers spend a lot of time outside, so we really try to remember to always wear a hat, stay in the shade as much as possible, drink lots and lots of water, and move a little bit slower than usual to keep our bodies from overheating. I’ll bet you do the same things on hot days (and if not, you should). Animals in the wild do those same things, too. They rest in the shade, find cool water for taking a little dip and drinking, and they keep their activity level low during the day.

Many of the animals at Oakland Zoo do other things to stay cool, as well, and some of them are a little weird – well, weird to us humans, anyway. For instance, griffon vultures and some other birds will poop and pee on their legs to keep cool – not exactly something most humans do! Other animals, like our Aldabra tortoises, estivate, which means that they go into a sort of sleep during hot weather, like a super-deep nap that lasts for months. Some mammals, like pygmy goats , lose a lot of fur, or shed when the weather gets really warm, so their coats aren’t so hot and heavy. If you see our elephants waving their ears during hot days, they are radiating heat from their ears: this cools down the blood as it moves through their ears first and then circulates through the rest of their bodies (this is how refrigerators work too). Our tigers pant – they breathe quickly through their mouths so the air going in and out will cool the moisture in their mouths. Our hyenas enjoy a cool dip in their water tub!Coolin' off!

Oakland Zoo’s animal keepers do lots of things to help our animals stay cool: we make sure they have shady places to rest in their enclosures, and we keep the doors to their night-houses open so they can go in and cool down any time they want – we even put fans in some of the night-houses.

We also give many of them popsicles to lick or eat. But, these aren’t your ordinary popsicles, though: some of our popsicles are made of fresh frozen juices and fruits, like the ones we make in big trash cans for our elephants; for our tigers, we create special meat and blood popsicles, and our otters get fish popsicles. I’m not so sure I’d like one of those as a snack, but our animals sure love them!We also make sure our otters have nice ice floes in their swimming water, and we use misters and hoses and swimming pits to help some of our animals stay cool. We even make sure our pigs and warthogs have big ol’ mud pits to roll around in and cool off. There is even a group of people (called the Taxon Advisory Group) who work with Zoos to make sure they only have animals that can live comfortably in the climate where the zoo is located.

As you see, we work very hard to make sure our animals stay cool in the heat and can enjoy the wonderful months or summer. Next time you are here on a hot day, be sure to look around see how many different ways you can find that we are making sure we have the “coolest” animals in town!

 

See you at the Zoo – and stay cool until then!

 

 

 

Western Pond Turtles get a hand at Oakland Zoo!

by | August 22nd, 2013
zena-the-zookeeperHey there, fellow conservation heroes! Do I have an important conservation program to tell you about today, and it’s taking place right here at Oakland Zoo!  It’s a ‘head start” program for the endangered Western Pond Turtle. These adorable little guys were once plentiful and lived all over the entire West Coast – from British Columbia in Canada, all the way down to Baja California near Mexico.

But today, they’re only found in a few parts of California, Oregon and a couple of places in Washington State. That’s because they’ve lost a lot of their habitat and are being eaten by non-native predators – including another kind of turtle that isn’t native to California.  It’s really sad. 
 
See how tiny the baby Western Pond Turtle is?  Because they grow very slowly in the wild, it takes them a long time to grow big enough to escape or fight off non-native predators like the American Bullfrog and Largemouth Bass who love to snatch them up and snack on them. The other species bullying these guys is the red-eared slider turtle. Many red-eared slider turtles were once somebody’s pet, but people sometimes release them into the wild when they get too big, and that’s bad news for the smaller, shyer Western Pond Turtle. Our little friend loses out to the bigger guys on food resources and warm spots to lie in the sun in their habitat.
 
But the GOOD NEWS is that we are raising hatchlings right here at the Zoo in our brand-new Bio-Diversity Center!  With our ZooKeepers taking care of these babies with plenty of nutrient-rich foods and veterinary care, they grow in just one year to the size it would take them three or four years to reach in the wild. Then, when we release them into the wild they are big enough to protect themselves and have a much better chance of survival. Right now, we are raising 44 Western Pond Turtles for release next year, and the babies are doing great so far!
 
So remember fellow conservation heroes, please don’t release pet turtles into the wild.  Help keep our lake areas clean, welcoming places for Western Pond Turtles. And be sure to teach others all about the amazing Western Pond Turtle!
