ZOOLOGY. 195 



They, at all seasons, sing their faint, lisping notes, repeated thrice, like those of the Blackcap. 

 I noticed a single pair of this species in California in November, 1855. In the evergreen 

 forests these birds are doubtless abundant. C. 



Abundant at Fort Steilacoom, Washington Territory, where it is a constant summer resident. 

 They are an unwary, unsuspicious bird, allowing near approach, especially while busily engaged 

 in feeding. Their habits in feeding resemble those of the other species of this genus, clinging 

 head down to limbs, and searching every crack or cranny in the bark for their insect food. S.

This diminutive titmouse is quite abundant during summer at Fort Steilacoom. I could 

 detect scarcely any difference in their habits from those of other species of the genus. They 

 arrive at Fort Steilacoom towards the middle of April. I have never seen one in Oregon or 

 Washington Territory during winter, and presume that they migrate to the south every 

 autumn. P. rufescens and P. occidentalls, on the contrary, can always be found throughout the 

 winter in greater or less numbers. S. 



The least chickadee, obtained by Townsend on the Columbia river, I have never seen north 

 of it. I saw it in great abundance in California. C.
