Belted
Kingfisher
Belted Kingfishers, as their name suggests,
subsist mostly on fish. However, they
occasionally consume other prey, including
crayfish, shellfish, squid, and terrestrial prey
such as small birds, mammals, lizards, and
insects. They have even been reported to eat
berries when other food is unavailable. Belted
Kingfishers typically sit at a waterside perch
watching for suitable prey, usually small fish
less than six inches in length. They make steep
dives head-first into the water. They may hover
and plunge vertically from heights of up to 50
feet into the water, occasionally disappearing
completely for a few seconds. They catch most
fish within two feet of the surface. To stop the
dive, they spread their wings under water. After
catching a fish, they will beat their prey on a
perch to immobilize it, then toss it into the air
and swallow it head-first. They may dismember
other prey, such as crustaceans and insects,
before consuming them. They disgorge indigestible
parts of prey such as fish bones and scales,
which may accumulate under favorite perches.
The nest site of a Belted Kingfisher is almost
always a tunnel excavated near the top of a
vertical bank. Nests may be several miles from
fishing grounds. Kingfishers may thus have to
defend two territories, one for feeding and the
other for nesting. They prefer sandy soil at the
nest site, but they may use gravel pits and even
the soil caught in the roots of fallen trees if
necessary. A pair takes turns digging a burrow
three to four inches in diameter using their
beaks and feet until the nesting chamber is three
to six feet from the entrance and slightly uphill
of it. The nest chamber is about one foot across
and six inches high. The female lays six or seven
entirely white eggs. Both parents incubate the
eggs for 23 to 24 days. The chicks hatch, naked
and blind, and their eyes remain closed for
another two weeks. With their sheathed feathers,
the chicks resemble tiny porcupines until the
17th or 18th day when the sheaths break and
expose full-grown feathers. The parents share in
the feeding of the young, announcing themselves
with a rattling call as they land on a dead limb
outside the burrow with a meal of fish. Only one
parent at a time enters the burrow.
When the young leave the nest after about one
month from hatching, they practice retrieving
fish dropped by their parents. They begin fishing
for themselves after ten days out of the nest.
Pairs separate after breeding and defend
individual feeding territories.
During the breeding season, Belted Kingfishers
range as far north as the Aleutian islands,
central Ontario and Labrador, and south
throughout the United States as far as southern
California, southern Texas and the Gulf Coast. In
winter they occupy the West Indies and as far
south as Panama and the northern coast of South
America. Some remain in the summer range, as far
north as they can find open water.

Kingfisher Range Map
Belted Kingfishers are one of a few species of
North American birds whose females are more
colorful than males. Females have a chestnut band
across the belly that is absent in males. Belted
Kingfishers are unlikely to be confused with any
other bird. Their huge bill, large head with
shaggy crest, and coloring are distinctive. They
are large (11 to 13 inches long) with blue-gray
head and upperparts contrasting with the white
underparts. Both sexes have a white collar and
broad band of blue-gray across the chest. Females
have chestnut flanks (usually concealed below the
folded wing) and a second chestnut band across
the belly. The large head and bill contrast with
the tiny legs and short tail, making Belted
Kingfishers look top-heavy.
