9. 3 (CoefE. of var. 4.4%) 



Two orange-crowned warblers were first heard by Frank Wil- 

 liamson on May 20 singing among the poplars and scattered spruce 

 along the slope of the bluff. Thereafter several might be seen in 

 that area daily, where they came readily and swiftly to a call. Fre- 

 quently a pair of birds came and pairs were seen among the earliest 

 orange-crowned warblers. Until May 28 these were the most com- 

 mon of the warblers, but thereafter water thrushes and yellow 

 warblers became much more numerous. This was in part because 

 of the rather limited areas in which orange-crowned warblers were 

 found. The testes of the males taken during the month showed no 

 trend in changing size. 



On June 1 a female contained an egg 5 mm. long, which must 

 have been nearly ready for laying. 



The nominate and most northern race of orange-crowned warblers 

 nests from Alaska to Quebec and winters widely across the southern 

 states. In Yukon this race has only been identified from Old Crow, 

 not from further south. The range of this eastern wintering race 

 seems to extend for about 1000 miles in arctic western America near 

 the border of forests. 



The Indians call this bird Tzi vit tick kwatlo.
