county. During migrations specimens which approach this form, 

 are found over the entire state, and such have been recorded from 

 Lincoln, West Point, and Kennedy. 



681d. *Geothlypis trichas brachidactyla (Swainson) — Northern Yellow- 

 throat. 

 This is the yellow-throat of the eastern portion of the state, where 

 it is an abundant migrant and very common breeder, arriving the 

 last week in April and remaining until late in September. Westward 

 it grades into and finally becomes replaced by the preceding form. 

 Omaha, Peru, Beatrice, Lincoln, Norfolk, West Point, Neligh, 

 Holt county, Niobrara valley, Long Pine, Cherry county — breeding. 

 The more western specimens are so nearly intermediate between this 

 and the preceding that it is difficult to satisfactorily place them. 



683. *Icteria virens (Linnaeus) — Yellow-breasted Chat. 



An abundant summer resident and breeder along the eastern edge 

 of the state and a little westward; arriving the first week in May, 

 breeding from late in May to July, departing in the middle of Septem- 

 ber. Omaha, Peru, Weeping Water, Lincoln, etc. 



683a. *Icteria virens longicauda (Lawrence) — Long-tailed Chat. 



This is the common chat of the state, of which breeding specimens 

 from Sioux and Cherry counties and the Niobrara valley are typical, 

 those from east central Nebraska grading into virens but nearer this 

 form. Over the whole state during migrations. Lincoln, Beatrice, 

 West Point, Neligh, Valentine, Thedford, Holdrege, etc. Dates 

 about as for preceding. 



684. Wilsonia mitrata (Gmelin) — Hooded Warbler. 



Aughey observed this well marked warbler along the Nemaha 

 river in southeastern Nebraska on several occasions in September, 

 1874. Recent observers have not recorded it. Breeding very prob- 

 able. 



685. Wilsonia pusilla (Wilson) — Wilson Warbler. 



This bird Aughey found sparingly in both eastern and western 

 Nebraska, and mentions especially one seen in southwestern Nebraska 

 along the Republican late in August, 1874. There is every probability 

 that this bird was a Pileolated Warbler, 685a. W. p. pileolata (Pallas), 

 which form occurs east across the plains to Minnesota and Missouri, 

 but in the absence of this or other specimens the status of this and 

 typical pusilla cannot now be determined. The Wilson Warbler 

 has been taken at both West Point and Omaha by Bruner, was found 

 to be a common migrant at Neligh by Cary, April 28 to May 13 and 

 Sept. 2, and was observed at Gresham by Dickinson. Breeds north 

 of Nebraska. 



686. Wilsonia canadensis (Linnaeus) — Canadian Warbler. 



Our only record of this bird seems to be the one by Aughey who 

 observed it in spring in the eastern part of the state and shot a single
