McGregor: Some Features of the Philippine Ornis 407 
Hirundo striolata (Boie). Whitehead records this species from 1,500 
meters in Benguet. Mosque swallows are abundant at low altitudes 
during migration, and some of theip are resident. Perhaps the breeding 
birds belong to a distinct race or subspecies. 
Hemichelidon griseosticta Swinhoe. Probably a winter migrant only. 
Common in the lowlands and found up to at least 1,200 meters. 
Muscicapula westermanni Sharpe. This appears to be a highland 
species; it is abundant at from 1,200 to 2,400 meters. 
Muscicapula luzoniensis Grant. From 1,200 to 2,800 meters; Whitehead 
found it commoner at higher altitudes than he did in Benguet. 
Rhipidura cyaniceps (Cassin). This is the Luzon representative of the 
forest fan-tailed flycatchers. It is common in the lowlands and at various 
altitudes up to 2,400 meters in the highlands. 
Rhinomyias insignis Grant. Whitehead collected this species on Mount 
Data at 2,400 meters, and I found it near Pauai at about the same 
altitude. It is probably confined to the mossy forest. 
Culicicapa helianthea (Wallace). A common highland species, from 
about 1,200 to over 2,800 meters. Also found in the lowlands. 
Cryptolopha nigrorum Moseley. Found at all elevations in the high- 
lands; it appears to be commoner at the higher elevations. 
Eumyias nigrimentalis (Grant). Abundant in the highlands at all 
altitudes; Whitehead records it from as low as 900 meters. 
Artamides striatus (Boddaert). I consider this to be a lowland species, 
but we found it at about 1,200 meters; Whitehead met with it at 2,100 
meters. 
Pericrocotus novus McGregor. Found at about 1,200 meters in Ben- 
guet and at about 2,400 meters on Polis Pass. This species probably 
occurs at all altitudes where there is suitable forest. 
Pericrocotus cinereus Lafresneye. This is a migratory species that is 
at times abundant in the lowlands; it has been found up to about 1,200 
meters. 
lole gularis (Pucheran). All species of lole are characteristic of the 
lowlands, but lole gularis is also abundant at about 1,200 meters in Ben- 
guet and occurs on Mount Pulog at about 2,400 meters. 
Pseudo tharrhaleus caudatus Grant. Very little is known about this shy 
bird; we got three specimens at about 1,200 meters in Benguet, but 
Whitehead found it only on Mount Data where he collected three specimens. 
It must be considered an exclusively highland genus until it is discovered 
in the lowlands. 
Zosterornis whiteheadi Grant. This species is abundant at all elevations 
above about 4,000 feet. It reaches the lowlands in northern Luzon. 
Brachypteryx poliogyna Grant. This appears to be an exclusively high- 
land species and is perhaps most abundant at from 1,800 to 2,400 meters’ 
altitude. 
Planesticus thomassoni (Seebohm). This black thrush is characteristic 
of the Luzon highlands above about 1,200 meters. 
Turdus chrysolaus Temminck. This Asiatic thrush occurs as a migrant 
in the Luzon highlands. 
Turdus ohscurus Gmelin. A migrant, like the last preceding. 
Oreocincla varia (Pallas). A migrant found by Whitehead at between 
1,800 and 2,400 meters.
