SO", 



song of the wood thrush, but instantly suggests the 

 latter. A nest of the Russet-backed that was built in a 

 roadside thicket between San Jos^ 

 and Alum Rock Canon contained, 

 May 20, three young Thrushes evi- 

 dently about a week old. 

 They were sparsely covered 

 with brownish gray down, 

 and pinfeathers were just 

 showing along the feather 

 tracts. Both parents dis- 

 appeared, and did not come 

 back so long as we re- 

 mained in the vicinity. 

 Fearing lest any attempt 

 to study the development 

 of the brood at close range ™^^'-" 

 would result in their being deserted by the parents, we 

 allowed the opportunity to pass by and did not visit 

 them again.
