My idea of this Mission 💯 is to identify and understand behavior of 100 species of birds found in India.
75: Black eagle (ಕರಿ ಗಿಡುಗ)
SN: Ictinaetus malaiensis
The black eagle is the only member of the genus Ictinaetus. They soar over forests in the hilly regions of tropical and subtropical South and Southeast Asia.
The black eagle is a large but slender eagle, at about 75cm in length and 148 to 182cm in wingspan. They are easily identified by their widely splayed and long primary "fingers", the characteristic silhouette, slow flight and yellow ceres and legs that contrast with their dark feathers.Sexes are similar, but young birds have a buff head, underparts and underwing coverts.
They are generally residents and no migrations have been observed. In a study in southern India, it was found to favour forests with good forest cover and was absent from areas where the cover was less than 50%.
The black eagle eat bats, squirrels and other small mammals, birds and eggs. It is a prolific nest-predator and is known for its slow flight just over the canopy. The curved claws and wide gape allow it to pick up eggs of birds from nests as well as swiftlets from caves. Along with swallow-tailed kites they share the unique habit of carrying away an entire nest with nestlings to a feeding perch.
The courtship display involves steep dives with folded wings with swoops up in a U shape into a vertical stall. They build a platform nest, 3 to 4 feet wide, on a tall tree overlooking a steep valley. One or two white eggs which are blotched in brown and mauve may be laid during the nesting season between January and April.The nest site may be reused year after year.
