In this small series the male and female tree sparrows at Old Crow 

 were a little lighter in weight than the respective averages of 18.4 

 and 17.7 grams found during several years at Anaktuvuk. 



The first male was collected on May 16. On the next day males 

 were singing extensively in the willow-alder brush near the village. 

 By May 18 many territories seemed to be settled but the numbers of 

 birds seen increased until May 24. Tree sparrows were then nearly 

 as numerous as Gambel's sparrows but not quite so conspicuous as 

 fox sparrows. In fact their arrival, settlement, and general behavior 

 was quieter than it was for most of the migratory species. By June 

 tree sparrows were widely distributed in grassy places and deciduous 

 brush, but not in the continuous spruce forest. They were found at 

 elevations 500 feet above the upper limit of spruce growth. 



On June 5 a nest with five eggs was foujid by Francis Williamson 

 at Driftwood Creek, where tree sparrows were uncommon in the 

 extensive spruce forests. Another nest with five half -incubated eggs 

 was found on June 29, one of the latest discovered. It might have 

 been a second attempt at nesting but was too early to follow a suc- 

 cessfully raised brood. 



The Indians call this bird Tchinkee.

In the grassy areas and willow-alder brush around Old Crow 

 Village white-crowned sparrows, which the Indians call Natsik, were 

 about equally as numerous as tree and fox sparrows. Wlierever spruce 

 was replaced by grass or deciduous brush they might be found. They 

 were about the conunonest species seen in the whole area. They were 

 above tree line, and a nest with five eggs was found at about 3,000 feet 

 on the steep, barren, dry, rocky slope of the second Old Crow Moun- 

 tain. Because of the extent of their varied habitat white-crowned 

 sparrows are considered the most numerous among the species of 

 Fringillidae nesting about Old Crow.
