Ornithology is the scientific study of birds.
Ornithologists study every aspect of bird life.
Some ornithologists look at how birds live in their environment, while others look at how the parts of birds work together to make a bird. Some ornithologists focus on how birds find food, while others focus on how birds digest food. Ornithologsts sometimes study how birds evolved and what their ancestors looked like, and still others study how birds are changing in today's environment and how they might be affected by ecological change in the future. Ornithology is a broad field, and there is room for everyone. Ornithology is one of the few sciences remaining where non-professionals regularly make significant contributions.
