Buteo buteo buteo (L.). 



Chiefly a winter visitor to the Oaniargue. Only two birds 

 seen, 



Haliaetus albicilla (L.). 



A fine adult seen on the shore of the Etang de Valcares 

 near the Isle Mornue. 



Circus aeruginosus (L.). 



The ]\r.arsh-Harrier was the most abundant Hawk in the 

 Cainaroue. 



Circus pygargus (L.). 



A single adult male Montagu's Harrier was seen near the 

 Etang (le Valcares. Considered a rare winter visitor by the

Circus cyaneus (L.).

 marshes. Though I never saw any open hostility, a Hen-

 Marsh-Harrier came along. 



Circus swainsoni Smith (= C. marrourus auct.).

 with dark wing-tips and tail and a few dark spots on the 

 neck and upper back. 



Accipiter gentilis gentilis (L.).

Ardea cinerea L.

 Purple Heron in winter, which is rare at that season. 

 Certainly I did not succeed in finding any. 



Egretta alba alba (L.). 



A single exainjile of this magnificent species was seen 

 towering among a flock of twenty-lour Common Herons on
