Stripes, white, faintly washed with yellowish, meeting across the fore- 

 head and extending backward almost uniting in a band across the occi- 

 put; wings and tail blackish; edges of outer webs of wing-coverts, and 

 quills, outer and inner webs of tail feathers, and tips of feathers of 

 lower back, rump and upper tail coverts, rufous; below, including 

 under wing-coverts, bright yellow; throat white; inner webs of wing 

 feathers, except at tips, rufous (juvenal male, Caicara,- Venezuela, 

 June 8, 1905, Geo. K. Cherrie, No. 3577, Brooklyn Institute Museum). 



Adults in fresh nuptial plumage show rufous edges to the tail 

 feathers. 



The nesting season along the middle Orinoco begins early in 

 April and continues into June. The nests are large, loosely woven 

 ragged looking balls of plant fibres and soft grasses, with a large 

 entrance hole on one side. They are usually placed near the ends of 

 large horizontal limbs and rarely more than 3.48 m. from the ground. 

 Two or three (rarely four) eggs are laid; they are speckled and 

 spotted with reddish brown, with a few underlying pale purplish 

 gray patches in some specimens. Usually the markings are confined 

 to a zone about the larger end, but occasionally are quite evenly dis- 

 tributed over the entire surface. The ground color varies from a 

 delicate white to a faint pinkish buflf. The form varies from ovate to 

 elongate ovate. A set of three eggs collected at Caicara May 10, 1907 

 (No. 14,735 Cherrie Coll.) measure 23.5 x 14.75 ! 22.5 x 14.5 and 22 x 

 14.7 mm. A set of two taken in the same locality, June 21st (No. 

 14,983 Cherrie Coll.) measure 23X 15 and 23X 15 mm.

Abundant from the delta region up to some distance beyond the 

 mouth of the Caura River. In 1897 and 1898 I found it common at 

 Altagracia, midway between Ciudad Bolivar and Caicara. Not at 

 all common at Caicara. Like the preceding species, it is an inhabi- 

 tant of the thinly wooded savannas. 



In life the eye is light brown to seal brown; bill and feet black. 



Birds in juvenal plumage resemble the adults, but are without
