NEW FINCHES OF COLOMBIA 

 One half natural size 



Yellow-headed and black-headed finches {Allaipeleii flaviceps Chapman and Atlapetes fusco- 

 olivaceus Chapman) are two of the 22 species and 115 subspecies described as new to science in 

 Chapman's Distribution of Bird-Life in Colombia. That so large a piece of systematic work on new 

 forms was possible is owing in part to the very large collection brought together which allowed 

 comparative study. The yellow-headed finch was found along the Rio Toche at an altitude of 

 6800 feet on the Quindio Trail of the Central Andes, and the black-headed species came from San 

 Augustin, altitude 5000 feet, Huila, Colombia. 



Of the family of finches(FringillidEe), more than 60 species were collected in Colombia. The birds 

 are distributed throughout the four life zones, but with a diminishing number of species as the alti- 

 tude increases; namely, 35 species in the Tropical Zone, 17 Subtropical, 11 Temperate, and 2 

 Paramo
