 1878, (Brown, C. B. P. p. 9) ; one taken at Westbrook, a young female, Sep-

 in the latter part of September, 1906, and a young male brought in by a cat, 

 September 17, 1906, (Brownson, J. M. 0. S. 1906, p. 106). York ; one at Saco 

 in September, 1885, one September 8 and another September 15, 1886, (Good- 

 ale, Auk 4, p. 77) ; an immature specimen taken at Eliot, September 12, 1894,

Our present knowledge of this species is limited but we are 

 safe in saying that it is one of the rarest of North American 

 Warblers. The extremes of its occurrence are August thir- 

 tieth and September twentieth, or in other words it occurs 

 chiefly in the month of September, very rarely then, and con- 

 fined, as far as the records show, in Maine to Cumberland and 

 York counties, indicating a migration route along the coast. 



The historic nest cited in connection with this species was 

 taken near Carberry, Manitoba, June 21, 1883, by Ernest S. 

 Thompson, and both parent birds with the nest and eggs are 

 in the National Museum. The nest is described as being com- 

 posed of dry grass and sunken level with the surface in the top 

 of a low mossy mound. The eggs were four in number and 

 stated to measure 0.75 x 0.56. Before being blown they are 

 described as delicate creamy white, with a few spots of lilac, 

 purple, brown and black, inclined to form a ring at the larger 

 end. (Auk 1, pp. 192-193).
