Birds of Kohat and Knrram. 
Not common in autumn and winter; but large numbers 
pass through in spring. Some individuals stay very late, 
and I have noticed them all through April and up to the 
20th of May. 
[1604.] Netta rufina. The Red-crested Pochard. 
Rattray, J. B. N. H. S. xii. p. 348 (Thall : occurs in 
March) ; Marshall, op. cit. xv. p. 354 (Quetta: common in 
winter); Cumming, op. cit. xvi. p. 698 (Seistan : common 
in winter, probably resident) ; Ward, op. cit. xvii. p. 948 
(Kashmir: common in February). 
Not common, but found throughout the winter at Dhand 
Tank, and occasionally elsewhere, up till the end of March. 
[1605J Nyroca ferina. The Pochard. 
Marshall, J. B. N. EL S. xv. p. 354 (Quetta: common in 
winter) ; Cumming, op. cit. xvi. p. 698 (Seistan: common 
and doubtless resident) ; Ward, op. cit. xvii. p. 948 
(Kashmir). 
Next to the Teal this is our commonest Duck in the cold 
weather. 
[1606.] Nyroca ferruginea. The White-eyed or Fer¬ 
ruginous Duck. 
Marshall, J. B. N. H. S. xv. p. 354 (Quetta: common in 
February) ; Cumming, op. cit. xvi. p. 698 (Seistan: common 
in winter) ; Ward, op. cit. xvii. p. 948 (Kashmir : a common 
resident). 
Less common than the last species, but fairly abundant on 
Dhand Tank in the winter. It leaves towards the end of 
March. 
[1609.] Nyroca fuligula. The Tufted Pochard. 
Marshall, J. B. N. H. S. xv. p. 354 (Quetta : common in 
March); Cumming, op. cit. xvi. p. 698 (a winter visitor in 
Seistan) ; Ward, op. cit. xvii. p. 948 (common, especially in 
March). 
I have only met with this Duck at Dhand, where it is 
abundant and occurs throughout the winter, at least up till 
the end of March.
