Species Spotlight:
Belted Kingfisher
Scientific Name: Megaceryle alcyon
Appearance:
Blue-gray back and wings, white belly with a broad gray breastband, females
have an additional rust colored breastband. Head has a distinctive crest
with a long, straight bill. Feet have the front two toes partially joined.
Wings and tail have white bars, white throat.
Size: 13 inches (larger than a robin).
Range: Alaska, Canada down to southern US, winters south to Panama.
Habitat: prefers streams, lakes, bays, coasts.
Food preferences:
eats almost exclusively fish, although they can also eat aquatic invertebrates,
amphibians, reptiles, insects, young birds, mice, and rarely berries. Young
are fed a regurgitant.
Hunting Technique: dives from a perch, or hovers and dives into the water from above.
Breeding:
Mates recognize each other by distinctive calls given calls given when approaching
the nest. Breeding usually occurs along watercourses. Both sexes are solitary
when not in breeding/nesting season.
Nesting:
a horizontal or upward-sloping burrow in a bank of a waterway, usually 3
to 6 feet in length but some have reached up to 15 feet. Rarely nests in
a tree cavity. Male and female alternately dig and remove detritus from cavity.
Lined with grass or a saucer of leaves.
Eggs: 1 brood per year, usually 6 - 7 eggs are laid. Both sexes incubate.
Chicks:
The young hatch 23 - 24 days after the egg is laid, and are hatched blind
and naked. Young huddle together for warmth, and are able to maintain their
body heat as a group at 6 days. About 23 days after hatching, the chicks
are fledged, and the parents begin teaching hunting skills. By 10 days after
fledging the young are able to retrieve small fish out of the water and are
driven out of the parent's territory.
Status: This
species is listed as one of the top 20 priority avian species of concern
identified by West Va. Partners in Flight. It occurs in West Virginia all
year long and is fairly common. They are listed as a species of concern
because they are such a great indicator of potential stress factors in riverine
ecosystems. Many West Virginians note a decline in kingfishers in recent
years around the State.
Notes:
As many may have guessed, the term "kingfisher" means "king of the fishers."
It is more interesting to look into the meaning of the scientific words
for the belted kingfisher. "Mega" translates to "big" and "ceryle" comes from the Greek word for "seabird". The second name, "alcyon",
comes from Greek also and goes back centuries into Greek mythology. According
to myth, a lady named Alcyon grieved so much for her drowned husband that
the gods took pity and turned them both into kingfishers.
Kingfishers are found the world over
and have very quick digestive systems, actually digesting the fish they have
swallowed as it inches down their throats. They eject pellets (in a similar
manner to raptors) and much data suggests that they are monogamous. Their
solitary nature when not in breeding season leads to them actually driving
off any other kingfishers during the rest of the year. A note attached to
one published description states that the size of the individual bird is
inversely proportional to the food abundance in their hunting area.
From what we have seen at the Center
these birds face more and more impact from free-roaming dogs. From the histories
we have been able to gather, the belted kingfishers that were turned in for
care had all been captured by roaming dogs and brought back to their masters
as a trophy. The great sadness is that due to the injuries the dogs gave
the birds in either the capture or transport, and despite even often desperate
measures taken by the dog owners, we were unable to save any belted kingfishers
this year.
