(265a) Fulica americana Columbiana Chapm. 



Fulica americana columbiana Chapm., Bull. A. M. N. H., XXXIII, 1914, p. 170 

 (La Herrera, Bogotii Savanna, Col.). 



Char, subsp. — Similar to F. a. americana, but tarsi and toes longer, bill heavier 

 and longer, frontal shield larger, higher, rounded posteriorly and more clearly defined 

 from the bill anteriorly; bill basally, in breeding specimens, yellowish; plumage, 

 particularly of the underparts, darker, more slaty; the under wing-coverts darker 

 with little or no white edgings; the white at the ends of the inner secondaries averag- 

 ing less in extent and confined largely to the inner web of the feathers. 



A locally common bird in the sloughs of the Bogota Savanna. Doubt- 

 less this form is deserving of specific distinction, but its relationships seem 

 best expressed by a trinomial designation. It is remarkable that while in 

 South America as in North America Fulica appears to be a Temperate Zone 

 bird, a nearly allied race of americana should be found at sea-level in the 

 West Indies.
