358 BIRDS OF ONTARIO. 



The ruiim' of this species is chiefly along the west coast or 

 middle district of the continent. In the east it occurs rarely. As a 

 straggler, I have met with it only < n t\v(t occasions, the latter heing 

 on the 11th of May, 1886, when a specimen was taken at the Beach 

 by K. C. Mcllwi-aith. Mr. 8aundei's mentions ha\ing ol)tained two 

 near I>,ondon, and Mr. Allan Brooks got one at Milton. 



It is a very plainly attired species, ;uifl niay readily be overlooked, 

 for there is nothing in its dress or inaiincf to atti'act attention, but 

 on close examination the coloi- of the rroNvn patch is a distinguishing 

 mark not likely to be mistaken. The .sexes closely resemble each 

 other, and the young are like them, except that they do not always 

 have the brown crown patch till after the first year. 



They are by no means C(jnspicuous birds, but they ha\e their (jwn 

 route to follow, and keep by it I'egularly eveiy season. 



Province, county, township, teiritory are passed quietl}' over till 

 thev reach the far distant land of Alaska, M'here Mr. Nelson says 

 they have been ol)ser\ed throughout the wooded region of the north 

 from the British boundary line, west to the shores of Behring Sea, 

 and north within the Arctic circle as far as the tree limit. They 

 breed throughout the interior, and Kennicott secyi-ed a set of eggs^ 

 on the 10th of June and another on the 15th of the same month.

This conipaiative length of whig and tail, with otlicr cliaiactcrs, jnohalily 

 always distinguisiies this species from tiie foregoing.
