However, these two species have non-overlapping distribution ranges and can be immediately told apart by trained observers, even at considerable distances. The Indian vulture is found only to the south of the Ganges and breeds on cliffs while the slender-billed vulture is found along and nests in trees. == Description == At 80 to 95 cm (31 to 37 in), in length, this mid-sized vulture is about the same size as its sister species, the Indian vulture.
