mm. They are a pale vinaceous buff, with two sets of markings, 

 one superimposed above the other. The inner markings are a pale 

 lavender greyish, the outer set ferruginous. In one of the eggs the 

 markings are scattered over the entire surface and consist of irregular 

 lines and dashes. In the other egg the markings are grouped chiefly 

 about the larger end and consist of irregular dots, spots and blotches.

These birds frequent the more thinly wooded districts or the edges 

 of thick forest region during the daytime, resting on the ground among 

 the fallen leaves, where their colors blend with that of the dead leaves. 

 I have never observed this species perched anywhere except on the 

 ground. At night they come out in the open savannas, and are fre- 

 quently seen about the doorways of the houses as well as out in the 

 country districts. 



About Caicara fresh eggs are found from early in March until the 

 end of May. There is no nest built and the two eggs are often deposited 

 in the most open, and what would seem dangerous, situations, on the 

 bare ground. Two eggs found on the 9th of March were near the edge 

 of thick forest bordering the river and almost directly in a path much 

 used by cattle, pigs, and other animals. The eggs lay on a spot of 

 bare ground about 8 cm. in diameter surrounded on all sides by dead 

 leaves. Incubation was far advanced and only one egg was preserved. 

 It is a pale vinaceous buff in color marked all over with irregular spots 

 and blotches of vinaceous brown; ovate in form and measures 28.5x21 

 mm. 



The male parent bird and a set of two fresh eggs were collected 

 May 5th. The bird, when flushed, feigned a broken wing to draw my 

 attention from the eggs. One of these eggs is elliptical-ovate and the 

 other between an elliptical-ovate and an ovate in shape. The mark- 

 ings are in two shades of color, those of a dark vinaceous overlying 

 others of pale vinaceous brown. They measure 28.5x21.3 and 

 28.4 x 20.5 mm.
