Do Swallows Swallow?
eat mainly flying insects, including mosquitoes and other harmful species,
so people benefit from swallows being around. And their graceful movements
are among the loveliest of any bird.
To catch enough flying insects for survival and good health, swallows
spend most of their waking hours on the wing, darting here and there to
sweep up small and large insects in their big, wide mouths. When they
aren't swooping about, they rest on branches or power lines. A scientist
who studied Barn Swallows once calculated that Barn Swallows fly about
600 miles per day just coursing back and forth capturing insects. During
migration, swallows are simply flying more in a straight line than back
and forth, and so unless they're flying over a large body of water where
they can't rest, swallows don't do much more work in migrating than they
do in their normal day-to-day living. Because they eat as they go, and
because they fly all day anyway, swallows tend to migrate by day (most
small songbirds migrate at nighttime). Once in a while a swallow gets
lost at sea, but swallows usually follow a land course as they migrate.
