3, the earliest, April 24, 1908. Eggs have been found from May 19 

 to June 21, but the maximum breeding period is from the first to

351 (757). Hylocichla aliciae (Baird). Gray-cheeked thrush. 

 Numerous specimens of this thrush have been taken in the basin 



but they are not scattered enough and field observations are not 

 certain enough to justify limiting dates. We believe, however, that 

 it is not an uncommon transient.

 backed thrush. 



Common transient. The average date of arrival is May 5, the

 been seen as late as June 8. Migrants begin to arrive from the north 

 about September 5 and are common from September 20 to 30. The

 pair breeding in the Fall Creek gorge in the summer of 1890.
