[Ibis, 
Buteo buteo buteo (L.). 
Chiefly a winter visitor to the Camargue. 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 Marsh-Harrier was the most abundant Hawk in the 
Camargue. 
Circus pygargus (L.). 
A single adult male Montagu’s Harrier was seen near the 
Etang de Valcares. Considered a rare winter visitor by the 
old French authors. 
Circus cyaneus (L.). 
The Hen-Harrier was common and was seen daily in the 
marshes. Though I never saw any open hostility, a Hen- 
Harrier would immediately leave a hunting-ground if a 
Marsh-Harrier came along. 
Circus swainsoni Smith (= C. macrourus auct.). 
A magnificent adult male was seen near Arles. At a 
distance in the bright sunlight it looked practically white, 
with dark wing-tips and tail and a few dark spots on the 
neck and upper back. 
Accipiter gentilis gentilis (L.). 
Apparently a rare bird in the Midi. Some boys flushed 
an adult in a pine-wood near Arles, and it flew out into the 
open over my head, giving me an excellent observation. 
Ardea cinerea L. 
This species was common, and apparently replaces the 
Purple Heron in winter, which is rare at that season. 
Certainly I did not succeed in finding any. 
Egretta alba alba (L,). 
A single example of this magnificent species was seen 
towering among a flock of twenty-four Common Herons on
