362 BIRDS OF THE REPUBLIC OF PANAMA PART 2 



tity under aureliae. This population, to me, appears specifically 

 distinct. 



Dr. Alden Miller (Univ. Cal. Publ. Zool., vol. 66, 1963, pp. 13-14) 

 in the mountains of Cauca, Colombia, described 2 nests of the race 

 H. a. caucensis as balls of moss 75 mm. in diameter "hung beneath 

 the arch of large fern fronds which partly protected them from 

 rain . . . The nest cup was a small pocket on top of the free side of 

 the ball." One held the usual 2 eggs. 



HAPLOPHAEDIA AURELIAE FLOCCUS (Nelson) 



Eriocnemis floccus Nelson, Smithsonian Misc. Coll., vol. 60, no. 3, September 24 



(Sept. 27), 1912, p. 8. (Cerro Pirre, Darien, at 1525 meters elevation near 



the head of Rio Limon.) 

 Eriocnemis floccns Nelson, in Simon, Hist. Nat. Trochilidae, pt. 2, Catalogue, 



1921, p. 374, in synonomy of Haplophaedia aureliae caucensis (error for 



E. floccus). 



Characters. — Male, similar to Haplophaedia aureliae caucensis 

 (Simon) of northwestern Colombia, but lighter green below, with the 

 crown greener, less bronze, and the upper tail coverts brighter 

 cinnamon. 



Female, distinct from that of caucensis in lighter, brighter green on 

 under surface; feathers of foreneck and breast edged and tipped with 

 white, with the green centers correspondingly reduced so that the 

 white is prominent, producing a strongly spotted appearance; above 

 differs as does the male. 



Measurements. — Males (3 from Cerro Pirre), wing 60.0-61.0 

 (60.1), tail 35.3-37.8 (36.6), oilmen from base 22.3-23.1 (22.6) mm. 



Females (8 from Cerro Pirre), wing 55.0-57.4 (56.2), tail 31.4-35.3 

 (33.8), culmen from base 21.5-23.5 (22.3) mm. 



Resident. Restricted to Cerro Pirre, Darien, where it is common in 

 the Subtropical Zone. 



During his work on Cerro Pirre in 1912 Goldman in his notes 

 regarded this "as the most abundant of hummers ... in fact one of 

 the most abundant birds." He noted particularly that the feather tufts 

 on the legs were conspicuous and easily seen when the bird was 

 perched, even when it was observed in profile. In view of his remarks 

 as to abundance it seems strange that this hummer was not included 

 in collections made by Benson who was at Cana from April to early 

 August 1928, or in those of Oliver Pearson who was on Pirre in 

 March and April, 1938. In addition to the 11 skins in the original
