xni. D, 6 Zimmer: Birds of Southern Palawan 335 



ARDEID^ 



Pyrrherodia manilensis (Meyen). 



On March 22 as I was floating down a river near Candauaga, 

 a heron of the present species flapped lazily across the river 

 in front of the canoe and disappeared in the mangroves that 

 lined either bank of the stream. Another individual was seen 

 on the reefs at Brooke's Point after I returned to that locality. 

 These were the only instances of the occurrence of this species 

 that came to my notice. 



Demigretta sacra (Gmelin). 



I saw the first blue reef heron at Brooke's Point on the after- 

 noon of March 17. It had certainly not been in the neighbor- 

 hood before that date. The following day at Sarong, farther 

 south, the species was common and still later it was seen at 

 Dadagican, Candauaga, and Bonabona. These are apparently 

 the first records for Palawan, although D. sacra has been found 

 on Cuyo and Balabac, and therefore its occurrence on the former 

 island is not entirely unexpected. Specimens were taken at 

 Brooke's Point and Sarong. 



Bubulcus coromandus (Boddaert). 



Indian cattle egrets were present at Brooke's Point, Sarong, 

 Dadagican, Candauaga, Bonabona, and Tagbariri. They were 

 not abundant at any of these places. 



FALCONID^ 



Accipiter virgatus (Temminck). 



At Calatugas on April 4 I saw a small hawk, which I am 

 certain belonged to the present species, although unfortunately 

 I was unable to secure the specimen. I refer it to A. virgatus 

 because that species, but none of its congeners, has been recorded 

 previously from Palawan. 



Spilomis bacha (Daudin). 



While crossing the mountains in the interior of Palawan on 

 March 26 I saw a serpent eagle circling about, which came 

 near enough to permit the recognition of its characteristic mark- 

 ings but not near enough for a shot. Palawan birds are refer- 

 able to S. bacha. 



Butastur indicus (Gmelin). 



The tic-wee buzzard was not uncommon in the more open 

 country back of Brooke's Point and was noted also at Calatugas, 

 Bonabona, Puerto Princesa, and Candauaga. If not soaring
