BLACK DRONGO (Dicrurus macrocercus)
is a small Asian passerine bird of
the drongofamily Dicruridae. It
is a common resident breeder in much of tropical southern Asia from
southwest Iran through India and Sri Lanka east to southern China and Indonesia. It
is a wholly black bird with a distinctive forked tail and measures 28 cm
(11 in) in length. Feeding on insects, it is common in open agricultural
areas and light forest throughout its range, perching conspicuously on a bare
perch or along power or telephone lines. The species is known for its
aggressive behaviour towards much larger birds, such as crows, never hesitating
to dive-bomb any birds of prey that invades its
territory. This behaviour earns it the informal name of
King Crow. Smaller birds often nest in the well-guarded vicinity of a nesting
Black Drongo. Previously considered a subspecies (Dicrurus adsimilis
macrocercus) of the African Fork-tailed
Drongo (Dicrurus
adsimilis), it is now recognized as a full species.They are aggressive and
fearless birds, and although only 28–cm (11–in) in length, they will attack
much larger species that enter their nesting territory.They are found as summer
visitors to northeastern Afghanistan and northern Pakistan but are residents
from the Indus Valley until Bangladesh and
into India and Sri Lanka.There are some cases of the Black Drongo preying on
small birds, reptiles, or maybe even bats. They
have also been on occasion seen feeding on fish Flowers of trees such as Erythrina and Bombax may be visited for water
and nectar and they are sometimes
known to feed on grains. They are
only rarely known to take larger arthropods such as scorpions and centipedes. They feed on milkweed
butterflies that
are often avoided by other predators and
are known to feed late in the evening or night, often on insects attracted to
artificial lights.[INFO:WIKIPEDIA]
