Insects help to supplement their diet as well. Finches can adapt to become year-round residents as the seed diet of the bird does not dissipate. The goose, female bird, and gander, male bird, are related to the duck and swan. The V-shape serves and important purpose. Each goose in the formation receives air lift from the bird ahead of it in position.
Migration occurs in the fall and spring of each year.
We'd like to thank Mr. Traina for helping us identify birds.
