CAPRIMULGUS GRISEATUS Walden. 
Abundant along the beach on Sibuyan, where specimens were 
frequently killed in broad daylight,? being flushed from the shelter 
of low vegetation. The nesting period appeared to have been 
finished, as we took several full-grown birds in young plumage. 
The adults were in many cases unfit for skins, having lost either 
several primaries or the entire tail. 
A pair of full-grown young birds differ from the adult in the 
following particulars: Underparts about the same shade of gray 
as in the adult but more finely mottled and with no spots of fulvous 
on the breast. The white spots on throat are just indicated, by 
white in the male and pale fulvous in the female. Upper parts 
blackish brown, very finely vermiculated with white, and lacking 
the conspicuous black blotches and fulvous edges of scapulars which 
are present in the adult plumage. The wings and tail are as in 
the adult. The young female differs from the young male in having 
the entire plumage washed with pale fulvous. 
Types.—No. 4487, male, June 15, 1904, and No. 4521, female, 
June 28, 1904, Sibuyan. 
Caprimulgus macrurus is credited to Sibuyan,* which if correct 
is no more curious than some other facts in the distribution of 
birds in Romblon Province. Mr. Worcester tells me that he 
remembers nothing about this record. 
SALANGANA MARGINATA (Salvad.). 
We have already recorded this little-known swift from the Islands 
of Luzon, Mindoro, and Calayan, and in the last-named island we 
collected immature birds. We are now prepared to present a few 
notes on its nesting habits as observed in Sibuyan. I was unable 
to visit the colony myself and so record the observations of my 
assistant, Mr. Andres Celestino, who collected the nests, eggs, and 
birds on June 11, 1904. He described the nests as being 6 feet 
from the ground and cemented to the face of a large rock which 
with two other bowlders formed an inclosure. There were forty 
1 All the specimens of C. maniilensis which we have taken were killed at 
dusk, just before it became too dark to see, at which time they were 
hawking for insects. I never but once saw a specimen in the daytime, and 
that was flushed from thick brush in Ticao Island. 
Since writing the above note I have flushed at midday a specimen of 
manillensis from a patch of thick brush near Manila.
