Birds of Indiana. 103-3 



Nest, on ground, under low bush; of grass and leaves. Eggs, 4-5; 

 white, marked with spots and blotches of reddish-brown and purplish- 

 slate; .63 by .49. 



This is the rarest bird of its genus in Indiana, and is only known 

 as a migrant. Usually it is very rare; often it is entirely wanting for 

 years together, and very rarely it is seen in some numbers. I have 

 found it in Franklin County but four times in nineteen years — April 

 29, and one day in May, 1880, May 9, 1885, and May 5, 1889. On 

 the next to the last date it was tolerably common in a sugar wood, on a 

 hillside near Brookville, in company with Nashville Warblers. In 

 1871, Mr. C. E. Aiken informs me, it was not rare in Lake County. 

 In that county, also, Mr. H. K. Coale obtained a specimen. May 16, 

 1877, and two days later one in Cook County, 111., not far away. The 

 next record I have from Cook County is of a specimen taken by Mr. 

 C. A. Tallman, May 16, 1897. In a bush on the edge of a woods at 

 Wabash, May 15, 1892, one was taken by Mr. W. 0. Wallace, and one 

 was obtained by Mr. A. M. Hadley at Richmond, May 1, 1897. Sev- 

 eral specimens have been taken in Marion County (Brayton). It has 

 also been reported from Knox and Gibson counties (Ridgway), Vigo 

 County (Evermann), Carroll County (Sterling), Dekalb County (H. 

 W. McBride). They return in the fall in September. Dr. Wheaton 

 heard it sing and describes its effort as a "loud, emphatic and rather 

 monotonous song, resembling as nearly as I can describe the syllables, 

 'chicky-tick-tick-tick-tick;' this song was louder and more decidedly 

 emphasized than that of any member of the genus with which I am 

 acquainted" (Birds of Ohio, p. 244). Mr. Ernest E. Thompson says 

 "it has a loud song-like chip-e-chip-e, chip-e, chip-e, chip-e" (ProG. TJ. 

 S. N. M., Vol. XIIL, p. 616).

 with no colored crown patch, but with a dusky stripe 

 through the eye and an indistinct white stripe over and

Remarks. — The adults of this and the two preceding species may be 

 distinguished with ease; immature birds, however, are frequently con-
