1082 REPORT OF STATE GEOLOGIST. 



282. (<>7.vO- Seiurus noveboracensis notabilis (KIDGWAY). 



GrinnelTs Water Thrush.. 







Similar to last species, but larger, darker above; stripe over eye and 

 lower parts more whitish. 



Length, 5.50-6.00; wing, 3.05-3.25; tail, 2.25-2.50; bill, from nos- 

 tril, .40-.50. 



RANGE. America, from northern South America, western United 

 States from Indiana to California, and north into British America. 

 Casual on Atlantic coast from northern New Jersey. Winters from 

 Gulf States southward. 



This western form of the Small-billed Water Thrush is found 

 throughout Indiana as a migrant and possibly as a rare summer resi- 

 dent in the northern part of the State. It appears to be the common 

 form in the lower Wabash Valley, and in the vicinity of Chicago, 111. 

 Mr. Ridgway writes me that "Water Thrushes from the Mississippi 

 Valley are very puzzling, but a large majority appear to be referable to 

 notabilis." One specimen that I sent him for examination from Brook- 

 ville, and two collected by Prof. W. S. Blatchley at Terre Haute, he 

 refers to this form. Mr. Ridgway took three adult males May 4 and 6, 

 1885, at Wheatland, Knox County, numbered, respectively, 104,998, 

 104,999, 105,000, U. S. Nat. Mus. Register. He says he has also taken 

 it in Wabash and Richland counties, 111., and there are specimens in 

 the collection of the National Museum from Warsaw, 111. They have 

 specimens from Wheatland and Vincennes representing both S. nove- 

 loracensis and S. n. notabilis. Mr. J. G. Parker, Jr., says this is .the 

 common form of Water Thrush in the vicinity of Chicago. Mr. F. M. 

 Woodruff informs me that Dr. J. A. Allen, to whom he submitted 

 some specimens from the vicinity of Chicago for examination, con- 

 siders them typical notabilis. Mr. W. adds all the specimens I have 

 from northern Indiana are this form. 



Migrating birds of this and the last species remain with us in spring 

 after the Large-billed Water Thrushes are breeding. They arrive early 

 in April and pass north late in that month, returning in August and 

 September; Brookville, August 13, 1881; Chicago, September 9, 1885.
