We carefully monitor the weight of our animals and now that we have acquired a new scale to weigh our hippos, we’re holding a contest to see who can guess the combined weight of our graceful 33-year-old Water Lily and the lovely 12-year-old Guadalupe. The winner gets to go behind the scenes to meet the hippos up close! Guadalupe with a snack. Photo by Dennis Dow/WPZ. Beginning today, Washington state residents are invited to guess the COMBINED WEIGHT of both hippos by entering online at www.zoo.org/hippocontest through midnight, January 27, 2012. The winning entry will be the closest to the combined weight (if more than one person gets it right, we’ll draw one random winner from those

Posted by: Kirsten Pisto, Communications Roses are red, violets are blue…unless you’re a tetrachromat, it’s true. Apologies for the obvious segue to a post about color, but I couldn’t resist!  A blue bellied roller and a brightly colored orchid show us examples of some of the beautiful colors here at Woodland Park Zoo. Photos by Ryan Hawk and Kirsten Pisto/WPZ. Throughout the animal kingdom, there is enormous diversity in the structure and faculty of eyesight. Oftentimes, we relate our own human eyesight to the visual capabilities of animals, but most evidence points to the contrary: in fact, humans might be an underdog in visual perception.

Our eyeballs have a ton of tiny little cones and rods in th

Posted by: Kirsten Pisto, Communications Unless you’ve been on a tropical getaway for the past month, you probably noticed that the Pacific Northwest welcomed in the coming winter season with regular drenchings of heavy rain. This is the time of year when leaves clog drainpipes, and puddles emerge on the streets, sometimes as big as ponds. Well, if you were a West African dwarf crocodile you would be very pleased!

Dwarf crocodiles ( Osteolaemus tetraspis ) are a special type of small crocodile species found in the tropical rivers and swamps of sub-Saharan West Africa and West Central Africa. They thrive in swamps and rainforest rivers, but have also been found in Savannah flood zones where they soak up the extra moisture during the wet season, and dig burrows in heavy mud to aestivate during the subsequent dry season.

Posted by: Diane Yoshimi, Zookeeper, with Linda Uyeda, Zookeeper Recently born Chinese crocodile lizard. Photo by Ryan Hawk /Woodland Park Zoo. Woodland Park Zoo recently had two female Chinese crocodile lizards ( Shinisaurus crocodilurus ) give birth to two litters of 11 babies in total. The crocodile lizard is an unusual reptile that gives birth to young after 9 to12 months of gestation. The newborn babies, weighing approximately 4 to 6 grams, are independent at birth and litter size ranges from 1 to 9. Since WPZ acquired a pair in 1993, there have been 70 crocodile lizard offspring born at the zoo. In December 2010 there were 115 individuals living in 22 North American institutions held in a managed program, meaning a studbook keeper recommends which individuals should be bred in order to maintain genetic diversity in the captive population.

Posted by: Gigi Allianic, Communications Holidoo is available now in ZooStores. Photo by Woodland Park Zoo. The zoo’s very own Dr. Doo has been hard at work specially crafting a limited edition blend of Holidoo for the holiday season. Unlike the typical Zoo Doo compost featuring manures of nearly two dozen zoo herbivore species, the All Elephant Poo Holidoo is made up exclusively of the “end products” of the zoo’s elephants’ manure and bedding—the biggest and richest composting materials at the zoo. ZooDoo — a work in progress. Photo by Ryan Hawk/Woodland Park Zoo. Got a gardening enthusiast in your life? Holidoo makes the ideal present. Or that person who seems to have everything? Bet they don’t have Holidoo! Holidoo's source. Photo by Ryan Hawk/Woodland Park Zoo. The festively packaged Holidoo product is available exclusively during the holiday season only at the ZooStore in jumbo-sized, 4-gallon containers ($20). Traditional Zoo Doo compost is also availabl

Posted by: Martin Ramirez, Mammal Curator A month after arriving to Woodland Park Zoo via FedEx from Little Rock Zoo in Arkansas, 7-year-old, female sloth bear , Tasha, underwent her quarantine exam on Tuesday. At Woodland Park Zoo, the quarantine exam is the last major step in the process to clear a newly arrived animal out of standard 30-day quarantine and prepare them to move into their exhibit. Dr. Darin Collins, the zoo’s director of Animal Health, inspects Tasha's teeth. Photo by Ryan Hawk/Woodland Park Zoo. Tasha received a full physical examination by our expert Animal Health staff that included blood work, radiographs and weight—essential baseline data that we keep on file to reference as we track an animal’s health over their lifetime.

Weighing in at 215 pounds, Tasha received a clean bill of health and has been approved to
