 WAGTAIL. 



The Ovenbird is a common migrant and a rare summer resi- 

 dent. It arrives in April, and departs late in October. 



The range of this species covers eastern North America, from 

 Alaska and the region of Hudson Bay southward, in winter, to 

 Florida, the West Indies, and from Mexico south to Panama. 

 It breeds from Kansas, the Ohio Valley and the mountain regions 

 of South Carolina northward.

In his "Catalogue of Animals Observed in Cook County, 

 Illinois/'* Mr. Robert Kennicott lists the Water-thrush and states 

 that it was known to nest within the County. Mr. E. W. Nelson, 

 in his "Birds of Northeastern Illinois" records this species and 

 says: "An abundant migrant; April 1st to May loth, and Au- 

 gust 25th to October 25th. Found everywhere in damp woods 

 or along the banks of streams during the migrations. A very 

 few remain to breed in secluded woods." 



Previous to the year 1880 varietal forms of this species had 

 been given no subspecific names. In that year, Mr. Robert Ridg- 

 way recognizedf Mr. G. B. Grinnell's separation of the western 

 form of this Water-thrush under the name Seiurus n&vius nota- 

 bilis which later became Seiurus noveboracensis notabilis Ridg- 

 way. It will be noticed that all the forms of this species were 

 included under the name noveboracensis at the time Mr. Kenni- 

 cott and Mr. Nelson made their observations. Since the time of 

 Mr. Nelson's list (1876), I have been unable to find more than 

 one authentic record of the taking, within our limits, of a typical 

 specimen of noveboracensis. In the bird collection of the Field 

 Museum of Natural History, Jackson Park, Chicago, there is a 

 specimen of the noveboracensis, which is a typical male of the 

 species, collected by Mr. Henry K. Coale at Grand Crossing, 

 Chicago, on May 21, 1887. This would indicate the possibility 

 of an occasional finding of birds of this species within our limits.
