Finches

Finches (Fringillidae)
Small birds with forked or notched tails, rounded or elongated bodies and round heads, with more or less triangular bills. The bill shape varies according to the principal type of food, from short and rounded to rather long and sharp. Some species are agile and feed while perching on, or hanging from, plants, while others are essentially ground feeders, but most also take insects from foliage in the breeding season. They have distinctive flight calls and simple, but sometimes musical, songs.
