207. Damophila juliae juliae (Bourcier). 



Eighteen specimens : Cincinnati and Fundacion. 



There is considerable variation in the amount of bronzy or coppery 

 sheen on the upper tail-coverts and upper parts generally. Two males 

 in transition dress are included (August 9 and 13). 



A single male was taken in the coffee-plantations at Cincinnati 

 (4,500 feet), but no others were ever seen there. At Fundacion it 

 was the most abundant of the family in August, being found in the 

 forest. It is a Tropical Zone form, evidently ranging in this region 

 over the alluvial plain around the Cienaga Grande and into the Mag- 

 dalena basin.

(Santa Marta localities and references). 



Twenty-two specimens : Bonda, Cincinnati, Dibulla, and Heights of 

 Chirua. 



Although this species appears to be subject to considerable variation 

 of an individual character, as well as that due to age, there do not seem 

 to be any essential differences between specimens from extremes in 

 its range, dark and pale birds occurring indifferently anywhere. The 

 guttural spot varies considerably in size and color, but is present in all 

 specimens examined. Individuals with buffy lores are probably imma- 

 ture. 



This hummingbird ranges through the Tropical into the lower Sub- 

 tropical Zone in this region. The only place where it has ever been 

 observed in any numbers is the hacienda Cincinnati, where it is always 

 abundant during the blossoming season of the guamas. It was fairly 

 common at Dibulla also, feeding among the flowers of a tree used for 

 shade in the cacaO-plantations. It is evidently a dweller in the forest 

 under natural conditions. It is one of the few hummingbirds which 

 has a sort of weak little song, often repeated while the bird rests in 

 the shade of the guamas.
