 in favorable localities.

(4484a) Agelaius icterocephalus bogotensis Chapm. 



Agelaius icterocephalus bogotensis Chapm., BuU. A. M. N. H., XXXIII, 1914, p. 

 191 (Savanna at Bogota). 



Char, suhsp. — Resembling A. i. icterocephalus but larger, the male similarly 

 colored, the female much darker, the head with less yellow, the back less distinctly 

 streaked, the margins to the feathers grayer, less yellow; the flanks and abdominal 

 region much grayer. 



It was surprising to find a race of this Tropical Zone species common on 

 the Bogota Savanna where it is apparently quite isolated from the ancestral 

 form which is not known to occur nearer than the marshes bordering the 

 Magdalena River over 8000 feet below.

(4488) Leistes militaris {Linn.). 



Emheriza militaris Linn., Syst. Nat., I, 1758, p. 178 (America). 



Taken only in the coastal zone. It has not been recorded from western 

 Colombia but occurs both in Panama and western Ecuador.

Sturnella ludovidann Wtatt, Ibis, 1871, p. 330 (near La Cruz; Cocuta Valley, 

 5000 ft.). 



This surprisingly close representative of our Meadowlark is an abun- 

 dant bird on the Bogota Savanna, and in arid regions it descends on both 

 slopes of the Eastern Andes to the Subtropical Zone. We first met with it 

 at an altitude of 6000 feet, on the Bogota trail, between ViUete and Faca- 

 tativa, and except for a brief interval at the lower border of the paramo on 

 the trail between Bogota and Villavicencio, it was continuously distributed 

 to somewhat below Quetame, or practically to the western limit of the forests 

 of the eastern ridges of the range.
