BIRDS OF THE REPUBLIC OF PANAMA PART 4 



Female (1 from Darien), wing 160.0, tail 39.6, culmen from base 

 27.2, tarsus 48.8 mm. 



Resident. Known in Panama from 2 specimens collected on Cerro 

 Quia, Darien. Both were taken by Dr. Pedro Galindo, an adult female 

 on February 21, 1970, at 760 m, near the trail leading down to the Rio 

 Mono, and an adult male near the same trail at 750 m on March 13 of 

 that year. The species was fairly common on the steep slopes of the 

 higher ridges, down to about 460 m, with a few noted as low as 300 m. 

 Though their low, tremulous, single-noted whistles, repeated con- 

 stantly at 2- or 3-second intervals, were heard regularly, the birds were 

 shy and were seen only occasionally, usually as they rose in rapid flight. 

 All observed were in adult plumage (Wetmore and Galindo, Proc. 

 Biol. Soc. Washington, vol. 85, no. 25, 1972, pp. 309-312). This species 

 is also found in northwestern Colombia.

Procellaria parkinsoni G. R. Gray, 1862, Ibis, p. 245. (New Zealand.) 



There are 3 sight reports of birds seen off the Pacific Coast of Pan- 

 ama that may refer to this species; one "almost surely this species" 

 seen 35 miles southeast on Punta Mala, Azuero Peninsula, on April 

 27, 1965, by Dr. George E. Watson; another that was probably this 

 species was seen west of Punta Mala on March 31, 1935, by Dr. James 

 P. Chapin; and "a large, all-black shearwater," suggesting this species, 

 was seen in the Gulf of Panama on November 9-10, 1958, by C. R. 

 Robins (Ridgely, 1976, p. 31). Parkinson's Black Petrel breeds on 

 islands off New Zealand and ranges east in the tropical Pacific as far 

 as the Galapagos Islands and off Central America (Jehl, 1974, Auk, 

 pp. 687-689).] 



[PUFFINUS PUFFINUS (Briinnich) : Manx Shearwater, 

 Pardela de Mann 



Procellaria puffinus Briinnich, 1764, Orn. Bor., p. 29. (Faroes and Norway.) 



There is 1 sight report of this species, a bird seen by an experienced 

 observer, R. Brown, in Panama Bay (08°44'N, 78°50'W) on October 

 30, 1977 (Ridgely, in lift.).]
