Family PARULIDAE: Wood Warblers 



Dendroica petechia amnicola Batchelder 



2 males May 31, 1954 weight 9.4, 8.9 g. 



These are the first records of yellow warblers obtained by Simon 

 Paneak, who collected them in the mountains. It may be that some 

 others have been mistaken for Kennicott's willow warblers. Several 

 times warblers which appeared too yellow for willow warblers have 

 flown swiftly past me. On the other hand I have observed several 

 hundred willow warblers until sure of their identification, and I am 

 therefore certain that other yellowish or greenish warblers are uncom- 

 mon. At present the information only suggests that the two yellow 

 warblers were visitors.

The specimen listed above is the only record of the myrtle warbler 

 from Anaktuvuk. Since the male birds are conspicuous as they sing 

 and feed in the tops of poplar trees in the wooded portions of Alaska, 



1 believe that they would be noticed if they were often present at 

 Anaktuvuk. I consider this example to be a visitor. 



Wilsonia pusilla pileolata (Pallas) 



2 males June 3, 7 weight 7.2, 6.9 g. 



These pileolated Wilson's warblers are the lightest adult birds that 

 I have examined in the Arctic. The first one, with a rapidity em- 

 phasized by its small size, flew to the top of a willow to sing, revealing 

 to me its clear yellow underparts and black crown. For 15 minutes 

 I watched its restless behavior and listened to its singing before it 

 withdrew into the thick low brush. I was sure of its attitude as 

 proprietor of the area. The next morning, after I had waited for 

 about an hour, it returned at about three o'clock to sing in the same 

 willow. In 1954 Simon Paneak obtained another example. 



From time to time in earlier years I had reports of small yellow 

 birds in the valley and I saw a warbler which I thought was brighter 

 yellow than Kennicott's willow warbler or the yellow warbler among 

 the willows along Contact Creek. Although the Nunamiut did not 

 know the pileolated warbler explicitly I suspect that some of these 

 elusive little birds will be found nesting in the mountains. 



After we had watched through the night for wolves to return to 

 their den, at about 3 a. m. I saw a male pileolated warbler sing twice 

 on a willow near the Ahlasuruk River about 130 miles west of Anak-
