Animal Update - August 17
Published August 24, 2012
Between our Baltimore and Washington, DC, venues, more than 17,500 animals representing 900 species call the National Aquarium home. There are constant changes, additions, and more going on behind the scenes that our guests may not notice during their visit. We want to share these fun updates with our community so we're bringing them to you in our weekly Animal Update posts!
Check our blog every Friday to find out what's going on... here's what's new this week!
New baby screaming piha!
We have a new baby screaming piha in our Upland Tropical Rain Forest exhibit!
Screaming piha chick
Our screaming piha chick is the first to be born in captivity in North America. After a month of patient waiting by our rain forest aviculturists and exhibit curators, the baby chick hatched at the end of July. Our staff is very excited to be able to share the news of this successful birth!
Very little is known about the biology of the screaming piha when it comes to reproduction, and we hope to learn and share with others in the community as much as we can about these Amazonian birds.
Laying eggs can be difficult for pihas due to their poor nest-building skills. They create tiny nests. Ornithologist (the branch of zoology that studies birds) Alexander Skutch once described a piha nest as being “the most meager arboreal nest that I had seen.” Our female’s nest was about 2 inches by 2 inches and was constructed of curling vines from around our habitat. To help support the structure of the nest, our staff added two additional branches. Soon the female began to sit on her nest and after a couple of days we had our first spotting of a light brown, perfectly camouflaged egg!
In the wild, camouflage is an essential part of the piha’s survival. As a single parent, the female piha often has to leave to gather food while the chick relies completely on camouflage to stay safe in the nest. Through this hatching, we’ve learned that piha chicks lay motionless with their wings at their side while the mother is gone. The chick doesn’t peep or beg (behaviors we traditionally associate with baby birds), so as to not give away its location to any predators.

In the last month, our baby piha chick has grown tremendously. Thanks to a great mom, the chick has had plenty to eat and is completely feathered. Our new family is currently under the observation of our staff and is not on display yet in our Rain Forest exhibit, but we can’t wait for you to meet our new addition!
