60 Wetmore, Birds of Culebra Island, P. R. peep 
— On April 12 a female of this species was secured in some mangroves. On 
other occasions I thought that I saw these hummers but was not certain. 
Apparently the species is a rare resident. 
34. Sericotes holosericeus holosericeus (Linnzeus). GREEN Carib. 
— Resident. These large hummers were common everywhere on Culebra 
but were especially abundant in the mangroves bordering the lagoons. 
The birds were tame and unsuspicious and showed considerable curiosity. 
They began nest-building in the mangroves the tenth of April and the 
breeding season was well under way at the time of my departure. Intrud- 
ing Honey Creepers and warblers were chased through the tree tops the 
hummers rattling their wings loudly. Though this sound was heard many 
times I was unable to explain how it was made. Several nests were found 
by watching the females. The birds flew to their nests without fear though 
sometimes I discovered that they were built only a few feet from my head. 
The nests were of the usual hummingbird type and were placed on small 
limbs from ten to thirty feet from the ground. The material in most 
of them was a soft cottony fiber taken from cactus, while externally they 
were covered with lichens. On April 19 a nest containing two heavily 
incubated eggs was collected. Others noted were still empty. Birds were 
collected on April 6, 8, 9, 10, 12, 15, 19 and 20. 
35. Anthracothorax aurulentus (Audebert and Vieillot). Porro 
Rican Manco.— Resident. This hummingbird was not common. The 
few birds seen were found in brush grown pastures. Specimens were taken 
on April 6, 10 and 19. A male in the National Museum collection was 
taken on February 11, 1899, by Dr. J. D. Milligan. 
36. Tyrannus dominicensis dominicensis (Gmelin). Gray Kinc- 
BIRD.— A common resident. Dozens of Gray Kingbirds roosted in the 
mangroves about the lagoon at Flamenco. In the morning at the first 
indication of coming light one would fly out calling loudly while others 
answered from below. From then until the sun was half an hour high the 
birds called incessantly from perches or on the wing making a considerable 
volume of sound. Following this morning concert they spread through the 
hills to feed. Signs of breeding were noted by April 10 and from then on 
the birds were often seen in pairs. April 13 one was seen carrying nesting 
material. Specimens were collected on April 6, 8, 10, 13 and 17. 
37. Myiarchus antillarum (Bryant). ANTILLEAN FLycATCHER.— 
On April 6 and 20 the unmistakable whistled notes of this flycatcher were 
heard near Punto Soldado but in the dense forest growth the bird could not 
be found. The species has not been recorded before from Culebra. 
38. Elainea martinica martinica (Linneus). ANTILLEAN ELAINEA. 
— Fairly common in suitable localities. I believed them to be summer 
visitants here as on Vieques. The species had not been recorded from the 
island until my visit. 
On Culebra the Elaineas frequented thick growths of cactus and spiny 
shrubs on the dry hillsides. They were more settled here than I had found 
them on Vieques in March. The birds moved about little, flying a few feet
