Anas penelope (L.), { = Mareca peneJope.^ 

 A coiniuon winter visitor from late September to April. 

 I saw a pair at Khu.slKlil on 20. vi. 



Anas angustirostris Menetr. 



I belit^e this bird to be a summer visitor at irreoiilar 

 intervals and in small (juantities, and a winter visitor in 

 small numbers.

 nor saw any ducklings. 



Anas querquednla L.

Anas crecca \i. 



A common winter visitor, commencing to arrive on

A common winter visitor, but large numbers are only 

 birds of passage. Not seen after 1*J. v. 



Netta rufina (Pall.). 



An uncommon winter visitor, occurring from October to

 it was by far the commonest Duck in a Ijad " Duck )'ear,"' 

 and over I'orty were killed in one day. Their minration 

 route must take a different line to other Ducks ; or else 

 they never tarry on their journey. 



Nyroca ferina. 



S.f.ferina (L.). 

 Vast numbers arrive towards the end of September and 

 remain throughout the winter, the bulk leaving in late
