ICTERFS BALTIMORE, {Unn.) Baud. 



Baltimore Oriole. 



Abundant at Pembina, the only locality where it was found. Like 

 the Bobolinks of this region, the Orioles acquire an extremely brilliant 

 plumage, in which the usual orange is often heightened into an intense 

 flame-color. The same intensity of coloration has been noted by Mr. 

 Allen in the cases of the Kansas Orioles. Several nests with eggs were 

 taken during the latter part of the mouth of June.
