The people who study birds are known as ornithologists. The goal of ornithology may be the study of any and every aspect of bird life. Some ornithologists focus on how birds find food, while others focus on how birds digest food. Some ornitholgists research changes in populations of birds across whole continents. Ornithologists study at how birds live in their environment, while others look at how the parts of birds work together to make a bird.
Some ornithologists reseach changes in blood cells in an individual bird.
Other ornithologsts 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 evolve in the future. The science of 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.
