62 Wermore, Birds of Culebra Island, P. R. ae 
47. Dendroica coronata (Linnezus). Myrrte Warsier.— There is 
a specimen of the Myrtle Warbler in the U. 8. National Museum secured 
by A. B. Baker on February 9, 1899. This species is probably a rather 
rare winter visitant. 
48. Dendroica petechia bartholemica Sundevall. Porro Rican 
YELLOW WarBLER.— An abundant resident. The mangroves bordering 
the bay Ensenada Honda were favorite haunts of these birds but many 
were found in the trees in the dry pastures. On the sandy beaches they 
were found in dense growths of Uvas de playa (Coccolobis sp.). In April 
they were paired and were about to nest. The males sang through the 
heat of the day, a song resembling that of Dendroica estiva. Several birds 
in odd transition plumage from juvenal to adult were taken. A series was 
collected on April 8, 9, 11, 12, 13 and 15. 
49. Compsothlypis americana usnez Brewster. NorTHERN Par- 
ULA WARBLER.— A common winter visitant. In April the Parula was the 
most common of the migrating warblers. On April 11 in a warm sheltered 
growth of mangroves I heard one singing and from then on they sang often, 
sometimes a mere whisper but usually as loudly as they do in their northern 
homes. ‘Two were collected on April 9 and the birds were observed until 
April 19. ; 
50. Mniotilta varia (Linneus). A winter visitant. One was taken 
from a small flock of migrating warblers on April 9. Another was seen 
on April 12. 
51. Coereba portoricensis (Bryant). PorTro RicAN Honry CREEPER. 
—A common resident. Honey Creepers were found everywhere on the 
island where there was cover for them. April 9 a bird was seen building 
a nest, as yet merely a loose ball of grass though the circular opening was 
already formed. Both male and female were seen working on other 
nests. This month apparently began a new breeding season. Young 
birds still having the superciliary stripe yellow were common. The Honey 
Creepers used their nests as roosts and I noticed that they did not appear 
in the morning until half an hour or more after other birds were active. 
A large series was collected between April 6 and 20. Grains of sand were 
found in 73 out of 149 stomachs examined from Porto Rico and the sur- 
rounding islands. This is strange as very little vegetable matter was eaten. 
52. Holoquiscalus brachypterus Cassin. Porto Rican BLackBIRD. 
— These blackbirds were said by Don Pedro Marqués to be found at times 
near Playa Brava. I saw none personally. 
53. Tiaris bicolor omissa (Jardine). Carin Grassquit.— A com- 
mon resident. At the time of my visit many of these Grassquits were 
breeding. Half a dozen pairs were nesting in the tall grass around one 
water hole. In other localities hundreds were feeding in the fields in loose 
flocks. On Culebrita these little finches were very common about the 
lighthouse. Many specimens were taken between April 6 and 20. 
54. Tiaris olivacea bryanti (Ridgway). Bryant’s GrassquiT.— 
A single male was collected April 8. No others were seen.
