Birds of Indiana. 1089 



Length, 4.90-5.75; wing, 2.15-2.55; tail, 1.80-2.25. 



Eangb. — America, from Colombia over eastern United States to 

 Britisli Provinces; casually to Greenland. Breeds from Nebraska, On- 

 tario and New York, north. Winters from Mexico, southward. 



Nest, in outskirts of woods or thickets, near ground; of weedstalks, 

 leaves and bark, lined with fine black rootlets or hair. Eggs, 3-4; 

 creamy-white, blotched and spotted with reddish-brown and lilac, 

 often chiefly arranged in more or less distinct wreath around larger 

 end; .71 by .56. 



The Mourning "Warbler is a rare migrant. Occasionally there will 

 come a few years when it is more common in some locality. From the 

 Whitewater Valley there is but a single record. They arrive some 

 years by May 6, and occasionally may be found until June 1. In the 

 latter part of May they are sometimes found associating with Geoth- 

 lypis agilis. Mr. Robert Ridgway says, at Wheatland, they '^became 

 suddenly very common. May 6, 1881" (Bull. Nutt. Om. Club, 1882, 

 p. 20). Mr. F. M. Woodruff informs me that he saw several in May, 

 1889, in the bushes along the shore of Wolf Lake, near Sheffield, Ind. 

 They were in company with 0. agilis. He also collected, two in Cook 

 County, 111., on the ridge between Hyde and Wolf lakes, near the 

 Indiana line. May 29, 1894. It seems to have been rather common at 

 Bloomington, the spring of 1885. The late Mr. C. H. Bollman re- 

 ported it May 16, 17 and 27. Mr. W. 0. Wallace says they were rather 

 common at Wabash, in open thickets, in the spring of 1892. 



Mr. H. K. Coale informed me that Mr. Geo. F. Clingman . shot a 

 specimen in Lake County, June 1, 1879. This specimen was sent to 

 the British Museum, where Prof. E. B. Sharpe identified it as 

 Geothlypis macgillivrayi (Aud.) (Cat. Birds, Brit. Mus., Vol. X., p. 

 365). Mr. Coale and Mr. Ridgway are both of the opinion that the 

 specimen is undoubtedly G. Philadelphia. From all southeastern In- 

 diana, including the Whitewater Valley, there is but one record of its 

 occurrence — Brookville, May 7, 1881. It was taken at Terre Haute, 

 May 10, 1887, and May 22, 1890; and in Carroll County, May 21, 

 1885 (Evermann); at Waterioo, May 8, 1890 (H. W. McBride); Peters- 

 burg, Mich., May 17, 1888 (Trombley); Manchester, Mich., May 20, 

 1893 (L. W. WatMns). It has been reported from Allen County 

 (Stockbridge). It may possibly be found to breed within this State, 

 though I have no account of its having done so. Mr. Ridgway has 

 found it along the borders of Fox Prairie, Richland County, 111., early 

 in June, 1871. They may have been late migrants, however (Orn. of 

 111., I., p. 170). Mr. Oliver Davie says: "It has been found nesting
