Ilab. — North America from Atlantis to Pacific. 



The Maryland yellow-throat is very common in the Territory during summer, preferring, a.s 

 usual, the bushes along brooks and swamps. I observed its arrival about the first of April, and 

 it remains until September.— C. 



I have obtained several specimens of this bird at Fort Steilacoom, in the neighborhood of 

 which they are always summer residents, but not in such numbers as the next species. — S.
