Of this hitherto rare bird, Mr. Frazar collected over one hundred and fifty 
specimens. These represent very fully the nuptial and late autumn plumages, 
but unfortunately do not include examples of the young in first plumage. 
The sexes are not certainly distinguishable, either by size or color, although 
the females average a trifle smaller than the males and are usually whiter be- 
neath, with less spotting on the throat. In spring birds the color of the under 
parts varies from creamy buff to light cream, or creamy white. November 
and December examples have the under parts pure, deep, almost ochraceous, 
buff. Fully ten per cent of the entire series show more or less ashy on 
the breast, this varying in tone and extent from a few pale gray, nebulous 
spots near the tips of the feathers to numerous brownish-ashy blotches which 
form a broad and almost solid pectoral band. This clouding is most common 
and pronounced in autumnal specimens, but some of these lack it wholly, 
while it sometimes occurs in spring birds, a few of which, indeed, are quite as
