"There is a good series illustrating the postjuvenal moult of the male, 

 which begins in July. The first nuptial plumage is evidently attained by 

 wear, the brown feather-tips wearing off more or less. The fully adult 

 dress is not assumed until the first postnuptial moult. The concealed 

 white shoulder patch •:« not present in all specimens." (W. E. C. Todd.) 

 Found fairly abundantly at the lower altitudes on both the Caribbean 

 and Pacific slopes, ranging from sea-level to a height of about 2,000 feet 

 in abundance, and found sparingly at greater altitudes. Its habits are 

 the same as those of the genus Sporophila, always being found in company 

 with S. corvina and morelleti on the eastern side, and S. aurita and more- 

 lleti on the Pacific. 



A nest taken July 16, 1905, at Guacimo, was very delicately built of 

 grass-stems and fine weed-fibres, hung between several tall stalks of grass, 

 three feet from the ground. The two eggs were bluish-white, thickly 

 speckled, dotted and blotched with markings of dull purplish-lilac, and 

 with numerous heavy spots of burnt umber, the markings being thicker 

 about the larger end, forming in one a cap and in the other a wreath. 

 Measurements: 16.5X13; 17 x13 mm.
