and 87 dead birds. Few of these fell from the lantern, as the wind 

 would have swept them overboard beyond the balcony. They were 

 killed by striking, not the lantern, but the framework of the tower. 

 This count probably represents not more than a. fourth of the injured 

 birds, as the Sombrero Key light is surrounded by water, into which 

 most of the birds that strike soon flutter or fall. Large numbers of 

 black-polls have also perished at two lighthouses on the south shore of 

 Long Island. At Shinnecock, September 30, 1883, 59 dead birds were 

 found around the light, and on the same day 230 were counted at the 

 foot of Fire Island light. The latest date of striking at these northern 

 lighthouses is October 20, 1882. The latest dates of passing fall 

 migrants at Raleigh are November 5, 1886, and November 1, 1889. 

 Some late dates from the Florida lighthouses are November 16, 1887, 

 November 4 and 10, 1888, and November 2 and 7, 1891. On the island 

 of New Providence, Bahamas, one bird was seen as late as November 

 26, 1898. 



The recorded appearance of the black-poll warbler at Bonda, Colom- 

 bia, on October 7 shows that the early migrants do not linger on the 

 road. The further facts that they are rare or accidental in Jamaica, 

 are not known in Haiti, -and are not nearly so common in Cuba as 

 might be expected from their numbers in the southeastern part of the 

 United States indicate that quite a large proportion of the species 

 make but short stops in the West Indies south of the Bahamas. Black- 

 polls appear to make a regular stopping place of the northern Bahamas, 

 but, except for occasional flocks, pass over the southern islands with- 

 out stopping. The records are not yet complete enough to show 

 whether the birds of Guiana come overland from Colombia or by way 

 of the islands.

Breeding range. — The summer home of the Blackburnian warbler is 

 in the forests of the northern portions of Minnesota, Wisconsin, Michi- 

 gan, New York, and New England. The species is also common in the 

 Catskill Mountains of New York and in some of the elevated parts of 

 Massachusetts, and a few also breed in the AUeghenian life zone of that 

 State and perhaps Connecticut, In Pennsylvania and through the 

 southern Allegheny Mountains to South Carolina, in both Canadian 

 and AUeghenian zones, a few also summer. Northward the species 

 extends to Cape Breton, northeastern Quebec, central Ontario, southern 

 Keewatin (Severn House and Trout Lake), and Manitoba.^ 



Migration range. — The range in migration extends westward to the 

 plains of eastern Texas, eastern Kansas, and eastern Nebraska, though 

 the bird is rare west of the forest region of the Mississippi. It has 

 been taken as an accidental visitant in Utah and New Mexico. 



Winter range. — A small body of Blackburnian warblers winter at an
