BIRDS COLLECTED IN THE ISLAND OF POLILLO. 105 



TRERONID/E. 

 Osmotreron axillaris (Bonaparte). 



This little pigeon was verj^ abimclant in thickets bordering the forest; 

 it was frequently noticed feeding on the fruits of Pandanus copelandi 

 Merrill. jSTame in Polillo, "punai.'' 



Pliapitreron amethystina Bonaparte. 



The aniethistine brown pigeon is kno-mi in Polillo as "cu-lu-cu-lu." 

 It was usualljr killed in fruiting trees of various species of Ficus § 

 Urostigma, but when not found in these trees it was rarely seen. Spec- 

 imens from Polillo, Luzon, and Bohol appear to be identical' in size and 

 coloration. 



Leucotreron marchei (Oustalet). 



On October 19 a female fruit pigeon, presumably L. mairhci, was 

 killed from a tree in deep forest. The plumage agi'ees in many points 

 with Grant's description, of the young male,- Init for the present this 

 identification must be considered provisional. 



Muscadivores chalybura (Bonaparte). 



This "balud," or imperial pigeon, was fairly abundant until a typhoon 

 swept the island during the night of October 24. After that date not 

 a bird of this species was heard. Possibly they moved to a part, of the. 

 island where the trees were less damaged. September 14 a male bird 

 was shot from a nest containing a single, heavily incubated egg. The 

 nest had been built in a large tree at a height of about 10 meters. The 

 egg is pure white and measures 46.5 by 32.3 millimeters. 



I recently have seen two living examples of a pigeon from Biilacan 

 Province, Luzon. I have no doubt these were M. nuchalis (Cabanis). 

 This is a very distinct species vsdth a large, well-defined patch of dark 

 chestnut on the neck. A note on this species will be published as soon 

 as specimens can be collected and compared with oilier material. 



IVlyristicivora bicolor (Scopoli). 



Early in October the nutmeg pigeon was found in some numbers near 

 the barrio of Burdeos on the east coast, and specimens were collected at 

 a later date near the town of Polillo. 



COLUMBID/E. 



Macropygia tenuirostris Bonaparte. 



One male and one female were collected; the species seemed to be 

 rare. 



'Ibis (1895), 469.
