OLD CROW 227 



The first blackpoll warbler was heard singing by Frank Williamson 

 two days before the first one was seen and collected on May 29. 

 Since they are considered common in far northern forests we searched 

 for them but saw fewer than of any other warbler around Old 

 Crow. At Kenneth Nukon's cabin, 15 miles east of Old Crow, black- 

 polls were common on June 3. The only nesting record was June 23, 

 when Sidney and Leonard Peyton collected the female specimen with 

 5 well incubated eggs. The first egg was estimated to have been 

 laid about June 12. 



The Indians call this this bird Tzi mt sitik kwarzui. 



At the U. S. National Museum, Bernard Feinstein remarked that 

 our blackpoll warblers and specimens from Alaska differed from 

 eastern specimens in having less black on the back and generally duller 

 gray upper parts, as described by Burleigh and Peters (1948), for 

 Dendroica striata lurida^ a form not recognized by the A.O.U. Check- 

 list (1957). The area in which intermediates between lurida and the 

 more eastern form were found was around Fort Severn, Ontario, and 

 Churchill, Manitoba, so that our Old Crow specimens were far from 

 the eastern border of the range of their race.

On May 20 the first northern waterthrush was heard singing in the 

 willows, above the noise of the river, and thereafter their loud clear 

 song could be heard, often at considerable distance from the swampy 

 willow brush. The male would fly to the top of a willow, sing his 

 series of notes about half a dozen times and then dive groundward 

 into the dense brush. Within five minutes he might be up again for 

 a period of song, this time on another willow, until after occupying
