2012-01-24 What is the most aerial Land bird?
The Common
Swift -Apus apus – is the most aerial of land birds, not landing in
3 years. Common Swifts are migratory and in midsummer they are found in the UK and northern Europe, while they winter much
further south in Southern Africa. These Swifts
have been known to live for as long as 21 years. It can survive bad weather by
entering what is called torpor, a coma-like condition in which its metabolism
slows to almost nothing.
Description
Common Swifts are
entirely blackish-brown except for a small white patch on the chin. They have a
short forked tail and very long swept-back wings. The sexes are alike.
Call
The call is a
loud scream in two different tone pitches, of which the higher one is from the
female and the lower one from the male. They often form 'screaming parties'
during summer evenings where about 10-15 gather and fly around in circles, all
calling out to each other.
Food
They feed on flying
insects and spiders which they catch in their beaks. Common Swift’s drink,
feed, mate and sleep on the wing.
Breeding
They will build
their nests in all suitable hollows in buildings, under window sills, in the
corner rafters of wooden buildings, in chimneys, and in smokestacks. A swift
will return to the same nesting site year after year, rebuilding its nest when
necessary. These swifts lay 2-3 eggs and breed and hatch the chicks together. The
young birds are ready to fly in about 40 days.
Conservation Status – Least Concern
Not threatened.
