292 ORKITHOLOGICAL EXPLORATIONS. 



The Blsick backed Kamtschatkau Wagtail is regularly seen on Bering 

 Island during the migration season, usually making its first appearance 

 in the early part of May, disappearing, however, towards the end of 

 the month. They are only seen single, or a few together, and although 

 convenient breeding places and plenty of food might be easily found, 

 still they never remain to rear their youug on the stony beaches of 

 the Commander Islands. 



Around Pctropaulski they are numerous. In 1883 they arrived in 

 the neighborhood later than usual, on account of the deep snow, which 

 covered the country down to the very water's line. The first were seen 

 in that year on the 15th of May, when I shot three out of a small flock 

 of six. But I had already observed the first Wagtail on the much more 

 northerly Bering Island eleven days before. In the autumn of the same 

 year the last one was seen at Petropaulski about the first of October, 

 but most of them had already left more than a week before that time. 



In habits and voice it resembles very much the European .1/. alba, 

 but seems to prefer the sea-shore to the banks of the creeks and rivulets 

 which are the favorite resorts of its coquettish cousin, M. melanope.
