INTRODUCTION. 



Pauai, or Haight's, is some 56 kilometers from Baguio, near the main 

 mountain trail between Baguio and Bontoc, in the subprovinee of Ben- 

 guet, Luzon, and has an approximate elevation of 2,250 meters. The 

 trail is built through forests of island pine, Pinus insularis Endl., while 

 the vegetation about Pauai is the mossy forest, characteristic of many 

 mountain tops in the Philippine Islands. 



The change in the flora from pine forest to mossy forest is very abrupt 

 and the line of demarcation between the two is as distinct as can be 

 imagined. The trunlvs and branches of the trees are covered with masses 

 of ferns, orchids, lichens, and mosses producing a striking and character- 

 istic appearance and many of the shrubs, grasses, and other small plants 

 are of genera different from those inhabiting the pine woods. ^. 



During May and June, 1908, with my assistant, Andres Celestino, 

 I made a collection of birds at Pauai. Of the twenty-two species col- 

 lected or noted in the mossy forest, only two, Pyrrhula leucogenys Grant 

 and Rhinomyias insignis Grant, appear to be confined to the mossy 

 forest, as all of the others have been collected at lower altitudes. The 

 poverty of the avian fauna of these high mountains is emphasized when 

 it is remembered that seventy-two species were recorded from Irisan, 

 near Baguio. 



In July we spent three days collecting in the mossy forest on Mount 

 Pulog, a peak some 10 kilometers east of Pauai and 2,800 meters in 

 elevation. On our return from Mount Pulog we were detained for a 

 few days at Lutab, a barrio of Cabayan, elevation about 1,000 meters. 

 Very few birds were noted in the vicinity of Lutab. Hirundo striolata 

 (Boie) was seen on July 5 and 6, an immature male of Chaimarrornis 



" This Journal Sec. G (1910) 5, Nos. 4, 5, with a paper on the flora of Mount 

 Pulog by Merrill and Merritt, will be found plates showing some of the botanic 

 and physiographic features of this section of Benguet.
