the southern part of the Cariboo District, B. C. (Brooks) ; Peace 

 River Landing, Alberta (Macoun) ; Fort Norman, Mackenzie (Pre- 

 ble) ; Prince Albert, Saskatchewan (Ferry) ; Fort Churchill, Kee- 

 watin (Clarke) ; Fort George, on the east side of James Bay 

 (Selwyn) ; Godbout, Quebec (Comeau) ; Anticosti Island, Quebec 

 (Verrill) ; Humber River, Newfoundland (Porter) ; and St. John, 

 Newfoundland (Howley). It was once seen at Cape St. Francis near 

 the Strait of Belle Isle (Bigelow). The southern boundary of the 

 normal breeding range extends from Buena Vista Lake, Cal. (Gold- 

 man) ; Pahranagat Valley, Nev. (Merriam), and Utah Lake, Utah 

 (Johnson), east to Barr Lake, Colo. (Felger), Wichita, Kans. 

 (Matthews), Henderson, Ky. (Alves) ; Variety Mills, Va. (Micklem), 

 and Cape May, N. J. (Hand). South of this normal summer range, 

 the species has been found breeding at Lerma, Mexico (Goldman) ; 

 Alamitos, Los Angeles County, Cal. (Robertson) ; Mormon Lake, 

 Ariz. (Mearns) ; Raleigh, N. C. (Brimley) ; and Yemassee, S. C. 

 (Wayne). 



Winter range. — The principal winter home is in the southern 

 United States, from which a few pass south throughout Mexico and 

 as far south as Coban, Guatemala (Salvin) ; Reventazon, Costa Rica 

 (Bangs) ; Cariblanco and Turrucares, Costa Rica (Lankester) ; 

 Laguna de Ochomogo, Costa Rica (Carriker) ; and Isthmus of 

 Panama (Lawrence). The species is not rare in western Cuba 

 (Gundlach), the Isle of Pines (Gundlach), and the northern Ba- 

 hamas (Bonhote). It winters north to Marysville, Cal. (Belding), 

 the lower Ohio Valley, and North Carolina; and is rare or casual 

 at Canton, 111. (Cobleigh), and Washington, D. C. (Coues). One 

 was seen December 28, 1904, at a warm spring near Fort Morgan, 

 Colo. (Felger), far north of the usual winter home. 



Migration range. — Specimens have been taken in Jamaica (Denny) 

 and Porto Rico (Gundlach), though the species is not known to 

 occur regularly in either of these islands. Many individuals have 

 found their way, spring and fall, to Bermuda (Jardine), though their 

 appearance there is so irregular as to suggest accident rather than 

 design. A straggler to Piddletown, England, became the basis of 

 the original description of the species.
