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 Caiion 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 jDarents dis- 

 appeared, and did not come 

 back so long as we re- 

 mained in tlie 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.
