CACATUID^ 



Cacatua haematuropygia (P. L. S. Miiller). 



Cockatoos were abundant throughout the forest at all points 

 visited except Dadagican. Owing to their active habits, their 

 conspicuous plumage, and their noisy, screaming voices they 

 were in evidence somehow most of the time. A certain dap-dap, 

 or coral, tree {Erythrina sp.?) in the forest near the settlement 

 at Brooke's Point was a favorite resort of these birds, and 

 there they frequently congregated in some numbers. Most of 

 the cockatoos had their ventral plumage stained brown with 

 some gummy vegetable substance, giving them a very dirty 

 appearance. 



On May 4 at Calatugas I saw a pair of cockatoos at a hole 

 near the top of a dead tree about 18 meters from the ground. 

 It was the only suggestion of nesting conditions that I noticed. 



PSITTACID^ 

 Prioniturus cyaneiceps Sharpe. 



Blue racket-tailed parrakeets were probably not uncommon 

 at Brooke's Point and elsewhere, but as they were neither very 

 noisy nor very conspicuously garbed they were not often seen. 

 Their note was a sort of harsh, grating squeak, which I heard 

 a number of times before I succeeded in associating it with 

 the parrakeets, but which after I had learned it often furnished 

 me with the first intimation that these birds were in the vicinity. 

 They easily concealed themselves in the foliage by the simple 

 process of sitting motionless, though they might be in plain 

 sight. Some of the individuals were in good plumage; others 

 had the feathers badly abraded, especially the terminal rackets 

 of the tail. Brooke's Point and Candauaga are the only local- 

 ities where these birds were seen. Specimens were taken at 

 Brooke's Point. 



Tanygnathus iucionensis (Linnaeus). 



The Philippine green parrot was very abundant in the neigh- 

 borhood of Brooke's Point. It congregated in flocks of greater 

 or less size, which frequented the forest, often in company with 

 the cockatoos whose noisiness was, if anything, excelled by the 

 vociferation of the present species. Like the cockatoos these 

 parrots were wary and alert, and although they might remain 

 in apparent indifference to the approach of an observer they
