Finches and Allies
The family Fringillidae includes 23 species found in North America.
Finches are small, seed-eating birds with pointed wings and conical bills. The tail us relatively short and notched. When flying, they have distinctive calls. The flight pattern is typically undulating, as if they were riding on a small roller coaster.
They nest in trees or bushes, building a cup-shaped nest from grasses and twigs. Clutch size is typically 3-5 eggs.
