BIBDS OF INDIANA. 1051 



distinguish them." Other Warblers linger later than they. Most 

 of them are gone from southern Indiana before May 5, though I 

 have record for Brookville May 7, 1892, and from Greensburg, May 

 14, 1893 (Shannon). By the latter date they have generally passed 

 our northern border. A few, some years, linger longer, especially 

 about the lower end of Lake Michigan. Prof. Evermann found them 

 in Carroll County May 22, 1883; Chicago, May 17, 1897 (Tallman); 

 Wolf Lake, Incl., May 30, 1894 (Parker). 



In the fall they begin to return the middle of September, and 

 promptly spread across the State, remaining with us, frequenting 

 woods, thickets and weed patches, even stubblefield overgrown with 

 rag weeds, often associating with other Warblers and Sparrows. The 

 first arrivals prefer the woods, and later they are noticed about the 

 fields and orchards. The earliest of fall arrivals at Chicago is Sep- 

 tember 15, 1896; at Bicknell, Ind., September 18, 1894; Brookville, 

 September 23, 1887. The last record from Chicago is October 3, 

 1896; Lake County, Ind., October 2, 1881; Carroll County, October 

 5, 1878; Lafayette, October 27, 1894; Brookville (where they did not 

 winter), October 29, 1887. 



The food of these Warblers is almost entirely insect food, and the 

 fact that they are found during their visits in almost every conceivable 

 situation., catching insects, renders them objects especially worthy of 

 our regard. Of 21 of these birds examined, one had eaten a moth; 

 two, twenty-one caterpillars, mostly measuring worms; five, fourteen 

 flies; fifteen, forty-eight beetles; one, four ichneumons; one, a caddis 

 fly; one, a spider, and one, fifteen tipulid eggs (King, Geol. of Wis., 

 I., p. 503). The results of Prof. Forbes' investigations show the same 

 kinds of foods.
