 41.'5. In winter, the colors, t'sju'cially of the iimiiature l>inls, aiv »jiiite 

 (lilfi'ient from those descrihtnl. The jiVuniauc of the adult, in whitei', dilfers 

 from that of spring' as follows: the lores and nasal tufts art^ whitish, instead 

 of pure, sharjdy detined l»la(l<, with, 

 however, some of the hair-like tihres 

 Idaekish. The ash ahove is a little 

 less clear, the white heneath less ]»ure; 

 the under mandihle whitish at the l»ase. 

 An immature^ bird, in winter, has the ash 

 ahove overlaid l»y a wash of reddish- 

 hrown, ]»rodiu'inii a jaevailinii" uniform 

 li^ht-hrown tint ; the black on side of 

 head is reduced to an obsolete ])at(h on 

 the ear-coverts. The didl white bi'iieath 

 is evervwhere — sometimes even on the 

 h>wer tail-coverts ^ — covi'ritl with nu- 

 merous bars (»f dusky, more shar])ly 

 defined, and darker than in the adult. 



Kastern s]>t'cimens a]>pear to have as nmch white on the rump as Wei^tern 

 ones. 



Haiuts. Tn the breeding-season this sju'cies of Shrike is found in all 

 North America north of the T'nited States, and is said to breetl also within 

 our territory, in mountainous distiicts. Such, at least, is the statement of 

 Mr. xVudubon, and Wilson leaves us to infer the same tiling by nivinj^ a 

 minute descri]>tioii of its nest and eiiiis. l>ut Audulx.n may have con- 

 founded this sjiecies with the r./r//A//(>/v>/VA.s, and Wilson, ajtparently l>elievinu 

 our sjHH'ies and the tvirnhifdr of Kurope to l»e identical, may have luul the 



Collyrio » jrnihitoroides.
