Cerchneis aparverius caucos Chapm., Bull. A. M. N. H., XXXIV, 1915, p. 375 

 (La Manuelita, Col.). 



Char, subsp. — Agreeing in size and general intensity of color with C. s. ochracea, 

 but male with the sides conspicuously spotted; crown darker, nape blacker, terminal 

 white areas on primaries usually not confluent; female with the crown and nape 

 averaging darker; male resembling C. s. sparveria in the coloration of the under- 

 parts, but crown usually without rufous; subterminal black bar on central rectrices, 

 much narrower; back with fewer bars; female darker above and more washed with 

 rufous below than the female of C. s. sparveria, the outer rectrices, quill-markings 

 and outer border of outer feather more rufous, the crown darker and with less or 

 with no rufous. 



Inhabits the Cauca Valley region apparently ranging from the Tropical 

 to the Temperate Zone, southward in the Tropical Zone to western Ecuador.

Cerchneis sparverius ochracea Chapm., Bull. A. M. N. H., XXXIV, 1915, p. 374 

 (excl. Venezuela specimens). 



The Sparrowhawk ranges from the Tropical to the Temperate Zone, 

 but although it varies widely faunally, not less than four forms being found 

 in Colombia, it appears not to vary zonally in that country. 



Thus the present form ranges from the llanos of eastern Colombia over 

 the. Eastern Andes to the Magdalena Valley and the eastern slopes of the 

 Central Andes. Northward it enters into Antioquia but in the Paramo of 

 Tama, on the Venezuela boundary, it is replaced by C s. ochracea Cory 

 (Pub. 182 Field Mus. 1915, p. 298) which, as Cory has shown, is distinguished 

 by the greater width of the subterminal tail-band. In the Cauca Valley it 

 is replaced by C. s. caucoe, and in the arid north coastal region by a pale form 

 of C. s. ochracea.
