39. Haematopus palllatus. Oyster-catcher. I was considerably surprised at the 
scarcity of this bird in such a favorable location. Only three of the species were seen, 
two on Padre and one on Bird Island. Probably a breeding species, and very likely 
more common than present data would seem to indicate. 
40. Colinus virginianus texanus. Texas Quail. One small flock of seven was 
seen on Padre, but the birds could be heard daily both on Padre and on the mainland. 
Data indicated the species as common, and it breeds on Padre. None was seen on Bird 
Island, and it is more than likely that the Padre Island birds do not travel across the 
Laguna Madre to the mainland, as there is an abundance of food on the island. 
41. Zenaidura macroura carolinensis. Mourning Dove. <A breeding species on 
both of the Bird Islands. On Big Bird five nests, each containing two fresh eggs, were 
found. These nests were in all cases among the nests of the Laughing Guils. Breeds

also very commonly on Padre Island. The doves were seen repeatedly going to the 
mainland for their food. 
42. Chaemepelia passerina pallescens. Mexican Ground Dove. About ten of 
this small species were seen, both on Padre Island and on the mainland, though none 
happened to be seen on Bird Island. Most likely a breeding species in the vicinity, but 
no nests were found. 
43. Scardafella inca. Inca Dove. Four were seen between Corpus Christi and 
Flour Bluff, and two more on Padre Island on May 31. Also probably a breeding species. 
44, Cathartes aura septentrionalis. Turkey Vulture. A common breeding spe- 
cies on the mainland, and in suitable places on Padre. Seen daily flying high in the 
air. Occasionally the birds visit Bird Island, probably attracted there by an odor that 
would drive most other creatures away! ; 
45. Cathartes urubu. Black Vulture. Distinctly less common than the preceding 
species, but seen almost daily from Bird Island. The species breeds commonly on the 
mainland, and also probably on Padre.
