Genus Troglodytes Vieill. 



24. T. aedoii Vieill, HOUSE WREN. Rather common summer 

 resident away from the immediate vicinity of the Lake. Arrives the 

 first of May and departs the last of September. 



25. T. parvulus var. hyemalis Vieill. WINTER WHEN. A com- 

 mon migrant. April 5th to May 1st, and September 12th to October 

 20th. 1 have found this species much more musical during the fall 

 migration than in the spring. 



Genus Cistothorus Caban. 



26. C. stellaris Caban. SHOUT-BILLED MARSH WREN. Rather 

 common summer resident and generally distributed in suitable places. 

 Breeds last of May. I think the distribution of this species is much 

 more general than is supposed. Owing to the character of the local- 

 ity in which they are found, and to their shyness, the chances are that 

 they will be overlooked. Before I learned their habits I passed re- 

 peatedly through places where I afterwards found they were quite 

 common. 



27. C. palustris Bd. LONG-BILLED MARSH WREN. Abundant 

 summer resident in marshy localities. Arrives the first of May, nests 

 the last of this month to the first of August. I have seen hundreds 

 of the nests of this species but have yet to see one attached to a bush 

 in the manner described in Baircl, Brewer and Ridgway's "North 

 American Birds" (Vol. I, p. 162)'. The nests I have seen have almost 

 invariably been placed in the midst of tall bulrushes, or wild rice, 

 growing upon a more or less submerged marsh, and are supported 

 about two feet above the surface, by being firmly attached to several 

 of the surrounding stalks, something in the manner of the attachment 

 of the Red-winged Blackbird's nest. The structure of the nests agrees 

 with the description in the above named work, with the exception of 

 mud never being used in nests I have examined. While the female is 

 incubating, the male is almost constantly employed upon the con- 

 struction of several unfinished nests, until often a pair may boast the 

 possession of a dozen unoccupied tenements. The supernumerary 

 nests are less substantial structures than the one occupied, and are 

 built indifferently of the living or dead grass leaves, the latter being 

 almost exclusively used in the structure occupied. 



Family MOTACILLIDJS. 

 Genus Anthus Bechst. 



28. A. ludovicianus Licht. TITLARK. Common in flocks along 

 the Lake shore and on bare prairies during the migrations. Arrives 

 about the 15th of May. It is then just assuming the breeding dress,
