8 Tue Witson BuLietin, No. 74. 
ronments of Adams. (Isle Royal Report 1908:133.) Along 
Quiver creek in the vicinity of Topeka, however, there are two 
fair sized prairie swamps, which were a few years ago mill 
ponds. The principal plant associations represented are the 
Scirpus validus (Bulrush) association; the cattail, the arrow- 
leaf, the Calamogrostis {a meadow grass), the Lythrum con- 
socies of the blazing star prairie, and the redtop-bluegrass 
pastur associations. The birds noted there during the early 
part of July befor the return migration had set in were as fol- 
lows: one pair of bobolirks, three pairs of meadowlarks, about 
fifteen pairs of red-winged blackbirds, a few indigo buntings 
and a half dozen short-billed marsh wrens. Additional species 
were noted toward the end of July after the beginning of the 
fall migration. All of these birds which occurred here dur- 
ing the summer proper are dominant species of this associa- 
tion where it occurs in other parts of the state. Altho they 
are not abundant in this locality, they illustrate a distinet avian 
group. The bobolink and short-billed marsh wren are index 
birds of this group. This is especially true of the bobolink, 
which is here nesting rather south of its usual southern limit. 
The other birds are as typical, but they are not so limited in 
distribution to this particular prairie swamp area.
