PAKHI DEKHOON PAKHI CHINOON...OBSERVE THE BIRD AND RECOGNIZE...BLACK DRONGO

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]
