This week's focus is on flight and migration. Birds that depend upon insects, fruit and other foods that are not available in the winter months, migrate to locations where these foods are abundant.
Birds fly from their summer breeding grounds to their winter locations along predicable routes known as flyways. A bird's summer and winter routes may use the same flyway or different flyways. Until recently migration routes have been difficult to study. New technology that allows researchers to record bird sounds at night has provided information about the flight paths, flight elevations and flight duration.
This week's lab focus is on the bird skeleton and muscles. Your observations in the field will allow you to correlate each bird's wing and tail shapes with their flight patterns.
