Junco hyemalis hyemalis (Linnaeus) 



2 males May 22, 1949, weight 19.5, 15.4 g. 



May 15, 1952 



Northern slate-colored juncos are not often seen in the mountains. 

 My only records are two taken by Thomas Brower at Tuluak Lake 

 May 22, 1949, and one seen at Nakrak May 9, 1952, in the same place 

 where the specimen was collected on May 15. The Nunamiut know 

 juncos and had described them for me before specimens were col- 

 lected. They call the junco Kayatavaurak. This name is like that of 

 the pine grosbeak Kayatavak, but with a diminutive ending added. 



1 could find no information about the nesting of juncos in the moun- 

 tains. Their appearance there is unusual, but the two specimens were 

 in good condition. I have seen numerous juncos raised in that season 

 in the wooded country along the Koyukuk and Alatna to the south and 

 a few have been reported along the Arctic coast (Bailey, 1948, p. 296) . 

 It is my impression that juncos may nest in the mountains and that 

 their occurrence represents migration. But from present evidence, 

 they can only be called visitors to Anaktuvuk.

The first western tree sparrows were recorded May 14, 1948, May 

 13, 1949, May 11, 1950, May 8, 1951, May 20, 1952, and May 14, 1953. 

 The latest date recorded is September 12, 1950, at Contact Creek. 

 During May 1949, the numbers gradually increased until 40 were ob- 

 served on May 30. This observation does not indicate the actual 

 abundance, for they were throughout the summer second in numbers 

 only to the redpolls, with which they occupied the same habitat of 

 the low willow patches, particularly in the flat bottom of the valleys. 

 They did not appear to venture to high elevations up the willow-lined 

 streams, nor away from the willows among the dry rocky places, as 

 frequently as did the redpolls and longspurs. They were usually seen 

 near the gTOund among the lower willow bushes. Specimens are from 

 Tuluak Lake, Kangomavik, and Contact Creek in Anaktuvuk Pass,
