The Zoo has thousands of birds in its collection, and not all of them are endangered. In fact, many of them are not even threatened. But that is not to say that the stable species will not be threatened sometime in the future. There is no way of knowing if the wild populations of an African bird may someday disappear, so the Zoo maintains happy, healthy populations as an insurance policy. The keepers who care for the birds do visual check-ups every day to make sure the animals are doing well and that there are no signs of illness.

If you have pets, you know that animals often add an element of unpredictability to life. Maybe your pups simply can’t grasp the concept of sharing their favorite toy. Maybe your cat doesn’t want to swallow its pill, or your bird just chewed up something important. Keeping a healthy, happy home for an animal can definitely be a challenge.
Bird keeper Michael Grue knows better than most how difficult it can be to maintain the health and happiness of an animal “home.” Each exhibit that is assigned to him is home to an animal family or two or three. A keeper’s day begins with a quick visit to each assigned exhibit to assess the general health of the animals inside. This requires a critical eye as birds will go out of their way to hide signs of weakness. Mr. Grue walked us through this observation process as we visited the Zoo’s pair of Bateleur eagles. (more…)
As you visit the Zoo, you may notice the extensive collection of birds exhibited throughout. In fact, there are more birds at the Zoo than mammals or reptiles. From passerines to song birds and waterfowl to raptors, the Zoo has a variety of birds that are common and highly threatened. The Zoo is home to some of the most fearsome and aggressive birds, including the harpy eagle Harpia harpyja and one of the most well-known in the world of conservation –the California condor Gymnogyps californianus.

At the genetics lab, I inspected Sumatran orangutan cells (to be prepared for the Frozen Zoo) under a microscope.
One of their core activities includes the maintenance of, and addition of samples to, the Frozen Zoo. The Frozen Zoo is a collection of deep-frozen cell cultures representing over 8,700 individuals from more than 800 animal species, many of which are endangered. The Frozen Zoo is a landmark step in conservation efforts worldwide because it provides specimens for research everywhere. By providing DNA of endangered and even some extinct animals, the Frozen Zoo helps researchers establish missing links in the ancestry of animals. It also aids with genome sequencing, or the mapping of all the genes in an animal’s DNA. In the future, the Frozen Zoo might even be used for cloning.

The area we surveyed for the potential quarentine pen.

Mackenzie and I work diligently on our topography maps.
Jean-Pierre Montagne, senior research technician at the Diego Zoo’s Institute for Conservation Research, taught and showed us the importance of maintaining biodiversity. Biodiversity refers to the variety of life within an ecosystem, for example the coastal sage scrub ecosystem. A wide collection of life within an ecosystem boosts productivity of the area, and ensures that it will be able to rebound after a disaster. Every species plays a role in an ecosystem, even down to the microorganisms living in the soil.
The term “guardian” typically applies to people such as parents, police officers or bodyguards. Of course, there are other types of guardians, and I met one in what may seem like a surprising place: the San Diego Zoo’s Wild Animal Park.
This guardian is Jean-Pierre Montagne, a senior research technician at the San Diego Zoo’s Institute for Conservation Research. Mr. Montagne holds a bachelor’s degree in ecology and evolution and has been working for the Zoological Society of San Diego since 1995 and has experience in other science fields besides animal ecology, including animal behavior and pathology. Now he works primarily in studying and protecting the biodiversity (variety of plant and animal life) in the area surrounding the Wild Animal Park. (more…)
It’s been my experience that Murphy’s Law (anything that can happen, will happen) is not only true, but is an active part of my life. On the same day Zoo Internquest planned to visit the Reptile House, my mom called me with the news that she had rescued a large tortoise, which was now residing in the back seat of her car. The next half hour was a frantic rush as I got the tortoise settled in a temporary house and then headed for the Zoo. As I hurried toward the Reptile House, I was eager to meet the best people possible to identify our find: the reptile keepers!
