Ill Monroe County, Prof. Kvcnnniin found it an uncommon summer 

 resident, and in Carroll County lie took it June 10, 1885. They 

 are usually later than the last species in arriving. 



The following dates show time of its first arrival: Brookville, May 



0, 1887, May li>, 1883; Davis Station, May 31; Laporte, May 30, 1896; 

 Lafayette, April 28, 1897; Plymouth, Mich., May 11, 1882, "May 20, 

 1895. Messrs. L. A. and C. D. Test found a nest, containing three 

 i\ggs, just north of Purdue University grounds, Lafayette, Ind., July 



1, 1893. The nest was about 12 feet from the ground and about 

 (i feet above it was another deserted nest. 



Traill's Flycatcher is the opposite of the Acadian in several respects. 

 It does not prefer the woods, but rather thickets, especially of alders, 

 in low, dam}) ground, the borders of streams and lakes. It also is 

 found in orchards. Its nests are usually placed in the crotch of a 

 husli 35 feet or less above the ground, and, instead of being loosely- 

 woven alTairs like the nests of the last species, are thicker and better 

 made, reminding one of the nest of the Yellow "Warbler, but not so 

 I'ompact. In Wayne County, Mich., where it nests commonly, Mr. Je- 

 rome Trombley, who has found twenty-five or thirty nests for several 

 consecutive yeai-s, says they nest in communities in willows by marshes; 

 nest in fork of a bush from three to six feet high (Cook, Birds of 

 Mich., p. 97). Mr. Otto Widmann says its notes sound like, wit-tit-che, 

 irif-ti-(jo, and are uttered when the bird is perched on the top of a 

 s|)rout or low tree, a telegraph post, or a fence stalvc. 



Full sets of eggs are found after the middle of June. An 

 egg is deposited each day; one brood is raised in a year. Incubation 

 lasts about twelve days. They return to their winter lunue in August 

 and early September. The following dates indicate the range of 

 (his migration: Brookville, August 13, 1881; Plymouth, Mich., Au- 

 gust 8, 1892, September 3, 1895. It is impossible to tell at this time 

 to what extent the eastern and western forms of this Flycatcher are 

 fdund ill Indiana.
