Milvus Cuvier, Lec. Anat. Comp., i, tabl., Ois., 1800.
Type, Falco regalis Roux = Falco milvus Linn.
The genus Milvus contains the three Kites distinguished by their long forked tails. The bill is comparatively weak, the culmen curved as in Haliastur and with similar cere and nostril; the wings are long and pointed, reaching to, or not quite to, the end of the tail; the third and fourth quills are longest, the first proportionately rather longer than in Haliastur ; tarsus and toes as in Haliastur but not so strong; the middle claw is dilated on the inside.
The genus is represented throughout the Old World.
Kirke-Swann has divided our Indian birds into two species (Synopsis Accipitres, pp. 96-8,1919), Milvus migrans and Milvus lineatus (melanotis auct.), but I can see no generic differentiation between these birds, nor do their breeding-ranges overlap.
