CHLOROCERYLE AENEA AENEA (Pallas): Least Green Kingfisher 
Alcedo aenea Pauuas, in Vroeg’s Catalogus: Adumbratiunculae, vol. 1, 1764, No. 
54 (Surinam), 
SPECIMENS COLLECTED 
1 ad. o&, Venezuela, Brazo Casiquiare, Raudal Corocoro, February 9, 1931. 
lad. o, Venezuela, San Antonio, Upper Orinoco, March 1, 1931. 
lad. #,1lim. 9, Venezuela, Cerro Yapacana, Upper Orinoco, April 4-27, 1931. 
Immaturity in this species is indicated by a brownish wash on the 
upper surface and by an increase in the amount of light markings on 
‘the webs of the secondaries and inner primaries. This must be taken 
into account in comparing specimens, as immature examples of true 
aenea show a fair amount of the light wing spotting and so suggest the 
northern form stictoptera, which is marked mainly by the presence of 
light marks across the secondaries and inner primaries. 
The typical race ranges north through Panama to the Canal Zone 
and beyond. The northern form comes south from Mexico through 
Central America into northern Costa Rica, intergradation between the 
two apparently taking place in central and southern Costa Rica.

The Cerro Yapacana specimens are mostly in fresh plumage; six of 
the nine do not have the webs of the rectrices worn away to form 
the terminal rackets. There is a great deal of purely individual 
variation in color, some birds being very brownish green on the breast 
and abdomen while others have no brownish admixture at all.
