Swifts are all over the world. There are about 71 kinds
of these birds. They fly around most of the day and only stop
flying once in awhile. They even eat while they are
flying. Sometimes they rest
on cliffs, in caves and in hollow trees. They like to nest in
places like that, too.
Their nests are made up of things they find while
they are flying around. The male and female swift put the nest
together with saliva when they are getting ready to mate. The
female lays from 1-6 eggs and she sits on them carefully so that
they are protected and warm. They hatch in 17-28 days.
The babies are called chicks. Chicks stay in the nest for one
to two months. They are fed a 'bolus' which is a gross
sounding glob of insects that comes from the mother or father bird's
throat. The chicks will grow fast or slow depending on the
weather. If the weather is good, the parent birds can get out
and get more food, more often. This makes the chick grow
faster. If the weather is bad, the parent birds don't go out
to get food because insects aren't out flying in bad weather.
Chicks that don't get a lot of food grow slower and stay in the nest
The Swifts have tiny feet and wings that
are long and narrow. They are brown, black, and
some have white throats.
Some swifts will migrate to some place warmer
when winter comes. Some swifts will hibernate. They will
go to their protected nests and go to sleep. Their sleep will
be for shorter periods of time with them waking up in between.
They still go through hibernation the same way that other animals
do. Their bodies slow down. Their heart beats and
breathing are very slow and their body temperatures drop.
Waking up helps the swifts because then they can try to get enough
food to hold them over when they go to sleep again.
