EUTOXERES AQUILA SALVINI (Gould). 



SALVIN'S SICKLE-BILL. 



Similar to E. a. lietenira, but white tips to rectrices averaging larger 

 and always much purer white. ^ 



Adults (sexes alike) . — Above metallic bronze-green or greenish 

 bronze, darker and duller on pileum, where feathers are narrowly and 

 indistinctly margined with dusky, the upper tail-coverts (sometimes 

 feathers of lower rump also) margined terminally with pale dull buffy ; 

 tail dull metallic bronze-green, the rectrices tipped with white, this 

 most extended on lateral pair, where the basal outline of the white 

 area on outer web is more or less transverse; remiges blackish slate or 

 dusky, very faintly glossed with violaceous, the innermost secondary 

 is usually marked with a narrow shaft-streak or subterminal spot of 

 dull white; chin, throat, and chest sooty black sharply streaked with 

 pale buff or buffy white, the breast and abdomen similarly marked, 

 but streaks narrower and less strongly contrasted (the darker streaks 

 more brownish) ; sides and flanks washed with metallic bronze-green ; 

 under tail-coverts dusky (glossed, more or less, with bronze-green), 

 margined with brownish buft' or pale cinnamon and with a narrow 

 shaft-streak of the same; maxilla black, mandible pale dull yellowish 

 (in dried skins), passing into dusky terminally; iris dark brown; legs 

 and feet pale browmish (in dried skins), the scutella darker, more horn 

 colored. 



Young. — Similar to adults, but feathers of pileum, hmdneck, back, 

 and rump more or less distinctly tipped with bufty, the upper tail- 

 coverts margined with the same, the greater wing-coverts very nar- 

 rowly tipped with buffy, and remiges with a minute apical spot of 

 dull wliitish (larger on secondaries).

c Compared with sixteen adults of E. a. heterura from Ecuad6r, twenty adults of E. a. 

 salvini (including one from I5ogotd) differ constantly and conspicuously in having piue 

 white tips to the rectrices, all the others having these markings dull brownish white as 

 well as less in extent.
