The fearless dude
Black Drongos (Scientific name: Dicrurus macrocercus), also known as King Crows, “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, including crows and birds of prey. This behaviour led to their name of King Crow. They fly with strong flaps of the wing and are capable of fast manoeuvres that enable them to capture flying insects.” [link] Clicked at Kalamassery in May/2015.
