Birds of Palawan. 41 



allies in the Philippines; 4 others are forms distinct from 

 those of either the Malayan or Philippine regions. 



The Malayan forms predominate by 36, as against 19 from 

 the Philippines; but there is a curious absence of several 

 weak-winged Malayan genera, such as Trogons and Barbets, 

 in the list. The Timeliine birds are all peculiar to Palawan, 

 and the two Pittas arrive from the Philippines ; so that if 

 there ever was any connexion between Palawan and Borneo, 

 or with any other Malayan territory now more remote, it 

 must have existed for only a short period of time. As 

 yet, I believe, no species of Merops has been met with in 

 Palawan, which is curious, as in the large adjacent islands 

 this genus is very plentiful. 



The species in the following list peculiar to Palawan are 

 marked thus f. 



Migrants *. 



P. = Philippine region only. 



M. = Malay region only. 



The nomenclature is mostly taken from Mr. Sharpens 

 article on my collection from Palawan published in this 

 Journal in 1888 (p. 193). 



1. Cacatua h^ematuropygia. P. 



Common ; generally met with in pairs ; has a slow flapping 

 flight, and often screams when on the wing. During the 

 heat of the day Cockatoos rest in the shade high up in the 

 trees, where they carry on their flirtations, screaming and 

 erecting their crests and performing many antics. Towards 

 evening they fly in flocks to the rice-fields, doing much harm 

 before the harvest. 



Eye black, orbit white ; bill pale blue, white at the tip ; 

 feet dull blue. Sulu, " Agi." 



2. Tanygnathus luzonensis. P. 



Very common. This Parrot is one of the first birds that 

 attracts the traveller's attention in Palawan, as it flies swiftly 

 from forest to forest in small flocks, screaming loudly. In 

 flight the wings are often kept much below the level of the 

 body. This species frequents the tops of high trees, feeding
