(Limosa fedoa) which was found all over the prairie wherever there 
was moisture. They seemed very fearless, and would fly around 
the intruder, or alight near him, uttering their shrill call. The dis- 
turbing of one seemed to arouse all within hearing distance, and 
they would come flocking together, and circle around, sometimes to 
the number of thirty or more. While feeding they seemed to go in 
flocks of from six to as many as fifty, upon the shores of the lakes. 
There seems to be a decided difference in the size of the sexes, 
which does not appear to be noted by authors, except Audubon, who 
states that the females are larger than the males. The bills are 
so very much longer in the females that the sex can be distin- 
guished by this means alone. The difference in a series of ten 
skins between the shortest bill of the females and the longest bill of 
the males is fifty-four hundredths of an inch, the average difference 
being ninety-three hundredths. The measurements are given in 
full in their proper place. 
In the following list the species were noted in both localities un- 
less otherwise stated. 
1. Turdus migratorius, Linn. Robin. — Several seen at Herman, 
but not apparently common. 
2. Turdus fuscescens, Steph. Wilson’s Thrush. — Common at 
Brown’s Valley. 
3. Mimus carolinensis, (Linn.) Gray. Catbird. — Common. 
4. Harporhynchus rufus, (Linn.) Cab. Brown Thrush. — A few 
pairs seen at Brown’s Valley. Nearly fledged young in nests, June 16. 
5. Troglodytes aedon parkmani, (A ud.) Coues. House Wren. — 
Common. A nest with fresh eggs, in a broken limb of a dead tree, 
found near Herman, June 7. 
6. Telmatodytes palustris, (Wils.) Bd. Long-billed Marsh 
Wren. — Common in marshes at Herman. Nests wifli fresh eggs taken, 
June 7. 
7. Cistothorus stellaris, (Licht.) Cab. Short-billed Marsh 
Wren. — Common in dry marshes. 
8. Eremophila alpestris, (Forst.) Boie. Shore Lark. — Common 
upon the dry prairie. 
9. Dendroeca sestiva, (Gm.) Bd. Yellow Warbler. — Abundant. 
Nests mostly just built or containing fresh eggs ; but an occasional one 
had young. 
10. Dendroeca pinus, (Wils.) Bd. Pine-creeping Warbler. — A 
single specimen, a female, was taken in the garden of a shanty on the 
prairie at Herman. A few small box-alders and poplars were all the trees 
within two miles or more. No nest was found, although these trees were 
very easily searched. It must have been only a straggler from the woods.
