Ernesta Wolf Offspring Located

Brookfield Zoo is excited to share some recent new from the Arizona Game & Fish Department. Ernesta (F1126), a Mexican gray wolf that resided at Brookfield Zoo from 2010-2012, her mate, and pups were introduced into the Mexican wolf recovery area in July 2014. Unfortunately, Ernesta was found deceased in the Gila wilderness recovery area in January of 2015. Without an alpha female present, the fate of Ernesta’s pack was unknown. Some pack members did not survive and others could not be located. Then this December, a trapper accidentally caught a male wolf in his trap...

Optimizing Dolphin Health with ZooMorphTrak

A new app developed at Brookfield Zoo can be used to estimate dolphin weights so that zoos, aquariums, and rehabilitation centers can continue to provide custom, optimized diets for each of their animals. These diets are continually monitored and revised for each dolphin based on their weight, age, growth rate, body condition, reproductive needs, and the season.

Establishing a New Endangered Mexican Wolf Pack

With the start of a new year comes a new breeding wolf pair at Brookfield Zoo. Last month, a 7-year-old male Mexican wolf, named Apache, arrived from Albuquerque Bio Park in New Mexico. Animal care staff is hopeful that he and 2-year-old Ela will have a successful breeding season this winter and produce a litter of puppies this spring. Coincidentally, Ela’s name means earth in the Apache Native American language.

MTags Around the World

A little more than two years ago, we introduced an exciting new research project (DTAG blog link) that used DTAGs (DTAG link) to look at the health and welfare of our group of bottlenose dolphins here at Brookfield Zoo. The DTAG, short for “Digital Acoustic Recording Tag”, is a type of bio-logging device used to track and monitor the movement of whales and dolphins. They function much like a Fit-Bit© by recording the acceleration, orientation, and depth of the animal. In addition, they record information about the environment including temperature, sounds the animals make, and ambient sound in their environment.

Changes Coming to Mexican Wolf Pack at Brookfield Zoo

This past July, the Chicago Zoological Society hosted the bi-national planning meeting for the Mexican wolf population, which was attended by colleagues from the United States and Mexico. During the three-day meeting, representatives from various organizations, including the U.S. Fish and Wildlife Service (USFWS) and the Association of Zoos and Aquariums (AZA), identified breeding recommendations for the current population and potential wolves for future release to the wild.
