and during the four nights October 14 to 17, 124 birds were killed 

 out of 322 that struck the light. Blackpolls have been reported as 

 seen about the light at Montauk Point, N. Y., from September 29 to 

 October 27, but no figures are available as to the number killed. At 

 Fire Island Light on the night of September 23, 1887, of the 595 birds 

 that were killed, 356 were blackpolls. In the fall of 1920 many were 

 killed around the light at Long Point, Ontario. From September 7 

 to 29, 236 were killed ; 199 of them between September 24 and 29. More 

 lately, on the night of September 10, 1948, four blackpolls were killed 

 by flying against the Empire State Building in New York City.

DENDROICA PINUS PINUS (Wilson) 



NORTHERN PINE WARBLER 



HABITS 



Both Wilson and Audubon, referring to its habitat and behavior, 

 called this bird the pine-creeping warbler, a most appropriate name; 

 but each gave it a different scientific name. Audubon's name, vigorsii^ 

 which stood for many years as the specific name, has given way to 

 pinus. 



Except on its migrations and some of its summer wanderings, this 

 warbler is essentially a bird of the more open pine woods. In east- 

 ern Massachusetts we have always associated the pine warbler with 

 the pitch pines {Pinus rigida), with their undergrowth of scrub oak, 

 that cover many miles of sandy barrens on Cape Cod and adjacent 

 regions ; where it is a quite characteristic and very common breeding 

 bird. We seldom see it in the denser forests of white pines {Pinus 

 strobus) that are the characteristic summer home of the black-throated 

 green warbler. Farther north it is sometimes found breeding in them, 

 but as a general rule it shuns them. Farther west it finds a congenial 

 home in the jack-pine barrens. Elsewhere it frequents Norway pines, 

 red pines, short-leaved pines, scrub pines, and other pines of similar 

 growth. N. S. Goss (1891) writes : "This species, as its name indicates, 

 prefers the pine trees, and usually makes its summer home in the 

 coniferous growths. I have, however, on several occasions met with 

 them during the early summer months in the heavily timbered bot- 

 tom lands, far away from evergreen trees, and during migration and
