A male in fine spring plumage was shot on Bering Island during my 

 absence in Petropaulski, May 21, 1883, and was prepared by my native 

 assistant, who also measured the total length and examined the sex. 

 Two weeks later I shot another specimen on the large tundra behind the 

 village of Bering Island, this one being a female. 



This beautiful species is only a rare straggler on the island, and its 

 appearance in the spring of 1883 was due to the same meteorological 

 circumstances which at that time brought so manj- rare birds over to 

 the treeless island from the dense w<*ods of Kamtschatka. 



On the peninsula I met it in the fall of the same year. Single indi- 

 viduals were observed in .the dense elder and birch thickets round Pe- 

 tropaulski. The birds were then silent and very shy, and kept them- 

 selves very quiet near the ground on the lowest branches. None were 

 seen after the 5th of October, when the la:st one was shot.
