The young of the year, resemble the adults in winter plumage ; 

 but the bill is smaller, and not grooved with white. The summit of 

 the head and nape is of an ashy-black. All the lower parts are 

 white ; this white, however, is clouded with ash, which prevails 

 equally upon the sides of the neck and towards the occiput, where 

 this color advances in the form of an angle. The bill is small, very 

 little elevated, deprived of the groove and scarcely hooked at the 

 point. The iris also blackish. It is then Mca pica of Gmelin and 

 others. 



In the summer plumage, the narrow band which goes from the bill 

 to the eyes is very pure white. The cheeks, throat and superior por- 

 tion of the forepart of the neck is of a deep black, appearing shaded 

 with a light tint of reddish. Inside of the bill bright yellow, the rest 

 as in winter.
