Swallow
A few, including the bank swallow, are called martins (see martins; see also wood sawallow; for sea swallow, see tern).
Swallows are small, with pointed narrow wings, short bills, and small
weak feet; some species have forked tails. Plumage may be plain or
marked with metallic blue or green; the sexes look alike in most
species.
Swallows spend much time in the air, capturing insects; they are among the most agile of passerine birds. For nesting, swallows may use a hole or cranny in a tree, burrow into a sandbank, or plaster mud onto a wall or ledge to house three to seven white, sometimes speckled, eggs.
