Birds of Prey

Our unit of study began with a discussion about birds of prey, or raptors. We talked about the difference between nocturnal and diurnal raptors, and about their nictitating membranes and how it protects them. 

Then, we began to concentrate on owls.  Though most are nocturnal, some are crepuscular too.  They have asymmetrical ears to help them locate prey, and they form and regurgitate pellets after eating.

Owl Pellet Dissection

The pellet contains the fur and bones of the owl's latest meals which it cannot digest.  By dissecting it, scientists can see what an owl eats and learn about local animal populations.

All 4th grade GT students had the opportunity to dissect an owl pellet; first virtually, and then with the real thing!  Everyone loved it, and found some great things, including a bird skeleton! 

The Philadelphia Zoo's "Zoo On Wheels" Program

After our unit of study, Miss Hunt surprised the class by inviting the Philadelphia Zoo to come and visit!  They brought four different birds: a Spectacled Owl, a Burrowing Owl, an Eastern Screech Owl, and a Harris Hawk.  We got to see all of them up close, and learned the differences between raptors and other birds.  It was AWESOME!
