Fork-tailed Drongo
Dicrurus adsimilis
The bird possesses a robust black beak and red eyes. When born, they lack feathers, exhibiting reddish skin, an orange beak, yellow gape flange, brown eyes, and a black beak. Juvenile fork-tailed drongos are dark brown tone with some buff-colored feather tips, a less pronounced tail fork, brown or grey eyes, and a pale mouth. While resembling adults, they lack the glossy shine on the lower body and display pale feathers on certain areas. Both sexes share a black body with a blue-green iridescence in specific regions. Voice: This bird is notably vocal, often commencing the dawn chorus and often is the last heard at dusk. Their pre-dawn calls comprise variations such as jwaaa-jwaaa and jeewy-jeeerr. They exhibit a diverse repertoire of vocalizations, ranging from sharp calls, brief whistles, and squeaks to fluid, raspy, and scratchy notes delivered rapidly or with extended pauses.
