ricarpus and Viburnum, which, with the scattered trees already men- 

 tioned, formed the only resort available for the tree- and bush-nesting 

 birds. Yet. in the three or four days spent here (June 28th to July 

 1st) about forty species were noticed within the limited area of our 

 rambles, twelve or fifteen of which may be regarded as tree- or bush- 

 nesting species. But generally only a few pairs of each species were 

 met with, the prairie species being the only ones really numerous. 

 As indicating the general character of the bird fauna of this almost 

 treeless region, I subjoin a list of the species met with, and remarks 

 on their relative numbers, giving first the arboreal species and then 

 the truly prairie forms, or those not materially influenced in their dis- 

 tribution by the presence or absence of trees. 



Mimus carolinensis. Two or three pairs seen. 

 Harporhynchus rufus. A single pair observed. 

 Dendrceca cestiva. A few pairs noticed. 

 Troglodytes cedon. One pair seen. 

 Sjnzella pallida. Only once or twice observed. 

 Euspiza americana. Several seen. 

 Goniaphea melanocephala. Several pairs seen.

 Tyrannus carolinensis. One pair seen. 

 Sayornis Sayus. One pair seen. 

 Coccygus americanus. One seen. 

 Zenozdura carolinensis. A few pairs seen.

The following list is composed mainly of prairie species, but in- 

 cludes also several swallows and hawks that cannot properly be 

 included among those of the preceding list : —
