ORNITHOLOGY. 



This is another of the rather numerous species which appear to in- 

 habit the entire temperate regions of North America. It is now fre- 

 quently brought in collections from California, and, from Mr. Peale's 

 observations, is evidently a constant resident in the western countries 

 of this continent.

A specimen in the collection, like that described by Dr. Heermann, 

 as above, is evidently in young plumage. The species, however, ap- 

 pears to be quite distinct from any other of North America, and is, so 

 far as we know, peculiar to the coasts of the Pacific. It has not been 

 figured. 



The present specimen is labelled as having been obtained in Oregon, 

 and this species is alluded to by Dr. Pickering as having been observed 

 in the month of August, 1841.
