Haliaetus leucogaster (White-bellied Sea-Eagle). 



An uncommon bird on the Kimberley coast-line. The blacks told 

 me that they often saw these Eagles carry away turtles, which they 

 caught by swooping down upon them as they rose to the surface to 

 breathe. In a subsequent trip to Bernier Island, off Carnarvon, 

 W.A., I noticed that these birds lived almost entirely on sea-snakes.

Erythrotriorchis radiatus (Red Goshawk).* 



A single specimen was secured. 

 Erythrotriorchis rufotibia (Red-legged Goshawk). 



(For description see Campbell, p. 249.) 



I saw four only of these new and fine Goshawks. On 1/5/10 a 

 pair took possession of the nest referred to under Hieracidea orientalis, 

 to which they added a few sticks and a lining of green cajaput leaves. 

 They were not seen again until the middle of June, and then only 

 occasionally, flying at a great height. On 30th June a bird was 

 noticed on the nest for the first time, and on the following day a single 

 egg was secured, the shell of which was already chipped, but I 

 managed to save it. Mr. White describes it thus : — Shape, round 

 oval ; colour, dirty white, without markings ; shell rather coarse, and 

 shows slight gloss; dimensions, 2.16 x 1.73 inches. As the nest had 

 been examined at a distance almost daily since the beginning of May, 

 and the sitting bird was not noticed until the end of June, I feel sure 

 that the process of incubation was carried on by the heat of the 

 sun during the day and by the birds only at night. The female bird 

 was secured on 30th June, and by 20th July the male had mated 

 again and commenced a new nest in a tall cajaput, about 50 yards 

 distant from the first nest. All attempts to procure the male failed.

Uroaetus audax (Wedge-tailed Eagle). 



Uncommon. 

 Haliastur girrenera (White-headed Sea-Eagle). 



An uncommon bird. The nests are built in mangrove trees on the 

 outer side of the coastal fringe, of sticks and a small quantity of grass 

 and sea-weed. Eggs were taken at Napier Broome Bay on 20/7/10. 

 Crabs and cuttle-fish are the principal articles of food. 

 Haliastur sphenurus (Whistling-Eagle). 



Were seen from i6th May to the end of July.
