Note 139 — Chapter XIII · KITES AND HARRIERS
D. C. (Douglas Craven) Phillott translation
The Kites have short tarsi, the Harriers, long. In the adult Harriers the iris is yellow, but in the immature birds, of several species at any rate, the iris is brown. The iris of the common Pariah Kite (Milvus govinda) is brown, while that of the “Common Kite” of England (M. regalis) is said to be yellow.
