Ornithology

Ornithology is a science that concerns the study of birds. The competition includes both identification of birds and questions about bird characteristics (anatomy, diet, range, etc). There are 185 species on the Official Bird List for 2010, which are separated into 19 orders. Any of the species on the Official Bird List may be tested on during the competition.

Overview of the Competition
This event is geared towards the study of birds. For this event you will most likely need to know how to identify birds and also their calls.
