Fall Migration. — The vicinity of Chicago is one of the few places 

 visited by the Connecticut Warbler during both spring and fall migra- 

 tion. Here the average period of fall occurrence is from August 31 

 to September 10, with extremes of August 30 and September 17. The 

 path of fall migration passes principally east of the Allegheny Moun- 

 tians and some dates of occurrence along the Atlantic slope are at 

 Saco, Me., September 8-15; Shelburne, N. H., September 14; Pitts- 

 ford, Vermont, September 20; Portland, Conn., September 17 to Octo- 

 ber 1 ; southeastern New York, August 26 to October 12 ; Engle- 

 wood, N. J., September 3 to October 1 1 ; Washington, D. C, August 

 28 to October 12; Raleigh, N. C, October 14-24; southern Forida, 

 October 9. So far as known, the Connecticut Warbler has not been 

 recorded anywhere during the half of the year from October 22 to 

 April 9. 



The Bird and its Haunts. — During the spring migration the 

 Connecticut Warbler seems to be confined to the Mississippi Valley 

 where, at this season, as well as in the fall, it is generally considered 

 a rare bird. In its return migration, however, it is often common 

 in the Atlantic states. At this time they may usually be found in 

 low, damp woods with abundant undergrowth, though not infre- 

 quently they are flushed from weedy growths bordering hedgerows 

 some distance from the woods. They are now excessively fat, no 

 other Warbler, as far as I am aware, approaching them in this 

 respect. While, locally Connecticut Warblers seem to come in flights, 

 being common some years and rare others, the census of light-house- 

 striking Warblers shows that the bird is a regular autumnal visitor. 



At Cambridge, Brewster 5 writes : "We used to find Connecticut 

 Warblers oftenest among the thickets of clethra, Andromeda ligus- 

 trina, shad-bush and black alder, which formed a dense swamp, and 

 in the beds of touch-me-not (Impatiens) that covered some of its 

 wetter portions. They were also given to frequenting the banks of 

 numerous intersecting ditches, especially where the deadly night- 

 shade, clinging to the stems of the bushes, trailed its gray-green 

 foliage and coral-red berries over the black mud or coffee-colored 

 water. In such places they often literally swarmed, but so retiring 

 and elusive were they that by anyone unacquainted with their habits 

 they might easily have been overlooked. They spent most of their 

 time on the ground under or among rank vegetation, where they
