In the southern half, at least, of Illinois the Orchard Oriole is 

 far more numerous than the Baltimore; and though much less 

 splendid in coloring is still a handsome bird, besides being an 

 excellent songster, his notes having an ecstatic character quite the 

 reverse of the mournful lament of his larger and more brilliantly 

 colored cousin. The more prominent characteristics of the species 

 are thus described by Dr. Brewer : 



"The Orchard Oriole is an active, sprightly, and very lively 

 species, and possesses a very peculiar and somewhat remarkable song. 

 Its notes are very rapidly enunciated, and are both hurried and 

 energetic. Some writers speak of the song as confused, but this 

 attribute is not in the utterance of the song, the musician mani- 

 festing anything but confusion in the rapid and distinct enunciation 

 of his gushing notes. These may be too quick in their utterance 

 for the listener to follow, but they are wonderful both for their 

 rapidity and their harmony. His performance consists of shrill and 

 lively notes, uttered with an apparent air of great agitation, and 

 they are quite as distinct and agreeable, though neither so full nor 

 so rich, as are those of the more celebrated Golden Eobin. 



"In the Central States, from New York to North Carolina, these 

 birds are not only very abundant, but very generally diffused. 

 Hardly an orchard or a garden of any size can be found without 

 them. They seem to prefer apple trees for their abode, and for the 

 construction of their nests. These structures, though essentially 

 different, are, in their style of architecture, quite as curiously 

 wrought and ingenious as those of the Baltimore. They are sus-
