1 38 Wood and Tinker, Rarer Birds of Michigan. [Amh 



Dendroica discolor. Prairie Warbler. — In 1881, Covert 

 found the species a rare one in the County, as it is at the present 

 time. On May 10, 19U1, a beautiful female was secured two miles 

 east of Ann Arbor, at the edge of a large brush pile in an apple 

 orchard. On May 9, 1903, a fine male was taken at the edge of a 

 tamarack swamp, and on May 2, 1905, two males were secured in 

 hazel brush on the banks of the Huron River below Ann Arbor. 

 The species was recorded but once in 1906 — May 4 — but in 

 1907 it appeared to be more numerous, although far from common. 

 In that year it was first noted on May 12, Avhen one was found in a 

 large apple orchard east of town and another in a brushy lot in the 

 same general locality, and again on May 13 (adult male), 14 

 (female) and 15 (female). The only record for 1908 was that of 

 one specimen noted in the vicinity of Ypsilanti on May 16. In 

 the season of 1909 four records for the species in this vicinity were 

 secured; the first on May 11, and the others on May 12, 16, and 18. 

 On all four of these occasions the birds were found in full song. 



Seiurus motacilla. Louisiana Water-thrush. — Covert appar- 

 ently found this Water-thrush rather common, as he wrote in 1881 

 as follows: "A very common summer resident, breeding in swampy 

 timberlands." Our experience with the species certainly does not 

 bear out this statement, as we have found it only as a rare summer 

 resident and migrant. On May 8, 1896, the species was found 

 breeding near South Lyon, by Covert and Wood, and this seems 

 to be the only breeding record for the County. On June 16, 1906, 

 an adult male was found dead on the college campus. The testes 

 in this individual were well developed showing that it was possibly 

 a breeding bird. Of late years it has been recorded nearly every 

 spring, as May 12, 1904, May 10, 1905, May 6, 1907, and April 26, 

 1908. But up to 1909 these are the only records we have, with the 

 exception of the single bird taken by W^ood on August 15, 1905. 

 In 1909, the species seemed to be more common, as it was frequently 

 noted in full song from April 28 to May 16. 



Oporonls agilis. Connecticut Warbler. — In regard to the 

 presence of this species in the County, in 1881, Covert says: "I 

 have secured one specimen in this County — May 17, 1880." We 

 have always found it a rare spring migrant and a very rare fall 

 migrant here, in fact our only fall record seems to be that of an
