Abundant. This species is found breeding most abundantly 

 throughout the dry season ; but, from my observations, 1 believe that 

 they are to be found nesting during every month of the year. The 

 nests are usually placed in small trees or bushes from I to 3.5 m. 

 from the ground, the average height not being over 2 m. A nest taken 

 at Caicara, June 27th was about 2 m. between upright forks, in the 

 top of a bush. It is globular in form, about 12 cm. in diameter with 

 a small round entrance at nearly the centre on one side. The mater- 

 ials used in construction are rather coarse and consist of dead 

 grasses, leaves, weed stems, strips of fibrous bark and pieces torn 

 from banana leaves. There is a lining of fine soft dead grass. The 

 three eggs found in this nest are ovate in form and measure 15.75 x 11.75 

 and 15.5x11.75 mm. 



On April 9, 1907, a nest and set of two badly incubated eggs were 

 taken at nearly the same spot where those described above were 

 found. This nest was about 2.4 m. from the ground. The eggs are 

 less thickly marked, although the individual markings seem larger. 

 In one they are pretty evenly scattered over the entire surface of the 

 egg, being massed together only in a comparatively small area about 

 the larger end. In the other egg the markings over the general sur- 

 face are tiny dots, but there is a band of color just at the point of 

 greatest diameter. The form is ovate, and they measure 16.75x12.75 

 and 17x12.5 mm. respectively. 



Another nest that was collected is very compactly built, com- 

 posed almost exclusively of very fine vegetable fiber woven into 

 spherical shape, and was securely placed between the upright forks of 

 one of the branches of a low shrub about i m. from the ground. 



Nests of this species, collectively, show considerable individual 

 taste in the selection of nesting material, and the finished nests indi- 

 cate that some birds are far more expert builders than others, their 

 finished work being compact and symmetrical, while that of others 

 has a slovenly, ragged appearance.

This race is included in our list based on specimens from the Paria 

 Peninsula (Cristobol, Colon) in the American Museum collection 

 which compared . with Trinidad examples seem identical. Thus the 

 range of this race is extended to the mainland.
