and greater coverts black and white, the new median and 

 lesser coverts black, the former occasionally with white tips. 



Juvenile. — The upper-parts are dark brown with a pale 

 buff spot at the tip of each feather, and the under-parts are 

 buffish-white, each feather slightly tip]ied with dusky-black, 

 giving a spotted appearance, the median and lesser coverts are 

 brown with pale tips, while the tail, wing-feathers and greater 

 coverts are like the adult in winter. Sexes apparently alike. 



First Winter.- The juvenile body-feathers and lesser 

 wing-coverts are moulted in July and August, but not the 

 rest of the wing-coverts nor the Ming-feathers or tail. F'irst 

 winter birds resemble the winter adults, but in both sexes 

 the inner secondaries have broader pale margins than in the 

 adults, and the median coverts have whitish tips, while 

 frequently a few unmoulted juvenile feathers with spots at 

 the tips are to be found in the iiiippieir-parts. The feathers of 

 the forehead of the .first wint/er ijUfiiJe' a])parently never have 

 white bases. Th€< iblaclvnes$ ,Qf the rump, tail- and wing-

 white on the forehead than the adult male, and is sometimes 

 less pure white on the breast. The wing-feathers are more 

 worn and brown than in the adult. Occasional examples, 

 though moulted, are much as in winter with scarcely any 

 black or blackish feathers on the upper-parts and have 

 many dusky-buf? feathers on the under-parts. 



Collared Flycatcher {Muscicajpa collaris). 



Adults.- No specimens in moult have been available for 

 examination nor have I been able to see any males in winter 

 plumage. The adult female in summer is much like that of 

 the Pied Flycatcher but is rather greyer on the upper-parts 

 and the bases of the feathers of the back of the neck and 

 upper rump are white, concealed in fresh plumage, but show 

 ing here and there when worn. In the male, as is well known, 

 there is a broad white collar and the back and upper pa it of 

 the rump are greyish- white. The primaries of the female 

 have more white at the base than in the Pied Flycatcher. 

 The winter plumage of the female is like that of the summer. 



Juvenile. — ^(No example seen.)
