| The Pied Kingfisher (Ceryle rudis) is
a kingfisher in the near passerine bird family Cerylidae, the water kingfishers.
It is the only member of the genus Ceryle.
It is common throughout sub-Saharan Africa
and southern Asia from Turkey to China. It is resident, and most birds
do not migrate, other than seasonal movements.
The Pied Kingfisher is estimated to be
the world's third commonest kingfisher, and is a noisy bird, unmissable
within its range.
It is mainly a specialist fish-eater, although
it will take crustaceans and large aquatic insects. It has evolved two
unique strategies, shared by no other kingfishers. It usually hunts by
hovering stationarily over the water and dives down bill first directly
below to catch fish.
The Pied Kingfisher can also deal with
prey without returning to a perch, and can, for example, catch a second
fish, or eat small prey in flight. These adaptations mean that this kingfisher
can hunt over the sea or in estuaries that lack the perches required by
other kingfishers.
This approachable largish (25cm) bird is
unmistakable, with its exclusively black-and-white plumage. Unlike some
kingfishers, it is quite gregarious, and forms large roosts at night. It
can be easily tamed.
Its nest is a hole in a bank, on its own
or in a colony, where it lays 3-6 white eggs. As with all kingfishers,
the nest of a Pied soon becomes unsanitary.
This species was initially believed to
be descended from an ancestral American green kingfisher which crossed
the Atlantic Ocean about 1 million years ago (Fry & Fry, 2000). However,
more recently, Moyle (2006) considered it more likely that the Pied Kingfisher
and the American green kingfishers are derived from an Old World species,
with the Pied Kingfisher or its ancestor losing the metallic coloration
afterwards.
