TURDID.E — THE THRUSHES — TUKUUS. 7 



of late years been found fiirtlier and farther to the west, until its known dis- 

 tribution has become that indicated above. Several specimens were obtained 

 in the \icinity of San Francisco by Mr. Lorquin, and formed part of the 

 collections sent to the Smitlisouian Institution l)y the llussian Telegraph 

 Expedition. 



This thrush breeds in tlie far north, more abundantly about Slave Lake, the 

 Lower Mackenzie and the L^pper Yukon Elvers. Like its congeners it is an 

 admirable singer, enlivening the woods with its melody. The nest is i)laced 

 on a low tree or bush, and the eggs are blue, with numerous reildisli 

 spots. Nest and eggs, indeed, are scarcely to be distinguished from those of 

 2'. ustulatus. Tlie two species, in fact, are closely related, but T. Swain- 

 soni will be readily distinguislied by the clear olive of the upper parts, in- 

 stead of reddish lirown, and the larger and Ijetter defined spots on the lireast.
