The migratory movements of the solitaire seem to be rather erratic 

 and during migration it is often found far east of its normal range; as 

 at Lake Johnston, Saskatchewan; Stonewall, Manitoba; one banded 

 at Wilton, N. Dak., on October 7, 1937; Falls Creek, Murray County, 

 Okla.; and Dallas, Tex. 



Casual records. — There are three records of the occurrence of the 

 solitaire in Minnesota: a specimen collected at Collegeville, Stearns 

 County, December 20, 1909; another taken near Fairmont, Martin 

 County, November 30, 1916; and one at a feeding station near Grove- 

 land from January to the middle of March 1922. A specimen was 

 collected at West Point, Wis., in February, 1910; and another in 

 Lake County, 111., December 16, 1875. An individual was under 

 observation near Toledo, Ohio, from December 26, 1938 to January 

 14, 1939. The easternmost record is from Long Island, where a 

 specimen was collected November 25, 1905, at Kings Park.

Family SYLVIIDAE: Warblers, Gnatcatchers, and Kinglets 



ACANTHOPNEUSTE BOREALIS KENNICOTTI (Baird) 



KENNICOTT'S WILLOW-WARBLER 



Contributed by Bernard William Tucker 



HABITS 



Kennicott's warbler is a race of — if indeed it is really separable 

 from — Eversmann's warbler (A. b. borealis) of the Old World. Ridg- 

 way (1904) stated that the Alaskan bird is smaller than the typical 

 race, with the color of the upperparts decidedly grayer (at least in 

 spring and summer plumage) and the underparts less strongly tinged 

 with yellow. It must be admitted, however, that the grounds for the 

 separation of the race kennicotti are not very secure. Ridgway gave 

 the average wing measurements of seven unsexed adults as 62 milli- 

 meters against 68.5 for males and 63.7 for females in the case of birds 

 from eastern Asia. Witherby (1938, vol. 2) gives the wing measure- 

 ment for the typical race as 62-71 millimeters in males (12 measured)
