222 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



Watson. A female in U. S. National Museum was collected at Nata, 

 Code, January 5, 1889, by Heyde and Lux. Griscom (Amer. Mus. 

 Nov. no. 280, 1927, p. 2) recorded 1 taken by Benson near Aguadulce. 

 Hallinan (Auk, 1924, p. 315) secured 1 at Corozal, Canal Zone, July 

 28, 1907, and W. W. Brown, Jr., collected a male near Panama City, 

 May 4, 1904. In 1963, from May 10 to 23, Storrs Olson and H. 

 Fischer took 3 males and 2 females in Panama near the Canal Zone 

 boundary beyond Albrook Field. Mr. Olson kindly loaned his speci- 

 mens for examination, so that their measurements are included in the 

 statement above. Gonads in males taken May 12 and 23 were 

 somewhat enlarged, indication of approach of the breeding season. 



The race albicauda ranges from Costa Rica through the Pacific 

 lowlands of Panama, and across the Caribbean lowlands of northern 

 Colombia, where it is recorded near the coast east to northeastern 

 Department of Magdalena. As a species, C. cayenne nsis extends 

 through much of Colombia and Venezuela to the Guianas and 

 northern Brazil, including also Aruba, Curasao, Bonaire, Margarita, 

 Trinidad, Tobago, and Martinique. 



The nest and eggs of the race albicauda so far as I am aware are 

 not known. The population of Trinidad (possibly distinct from 

 C. c. cayennensis of the adjacent mainland, as the subspecies leopeltis) 

 according to Belcher and Smooker (Ibis, 1936, pp. 23-24) places its 

 2 eggs on the ground. They are described as rounded oval, with the 

 ground color buff, marked with irregular lines of dark brown, and 

 spots and small blotches of pinkish brown and lavender-gray. In 2 sets 

 of 2 and 1 single egg measurements varied from 24.5-25.5 X 19.3-19.5 

 mm. Father Pinchon (Faun. Antill. Frang., Dec, 1963, pp. 156-157) 

 found the race of Martinique, which he named Caprimulgus cayennen- 

 sis manati, nesting as is usual for this species, on the bare ground. Its 

 2 eggs, which measured 25-26 X 19 mm., were cream colored, marked 

 in general like those of the birds found on Trinidad.
