Denclroioa blackburniae. 
Lake Umbagog, Maine. 
West and eggs. 
1896. 
^xOne of the nests found (by me) on the 2nd (in the woods 
June 6. at the W. extremity of the Mason logging works) yielded to¬ 
day a remarkably handsome set of 4 eggs of the Blackburnian 
Warbler. Although they were perfectly fresh the female sat 
so closely that thumping and shaking the tree (a slender one) 
failed to start her and when Watrous climbed it he nearly 
touched her before she slipped off. She then dropped like a 
stone to the ground over which she crawled and tumbled and 
fluttered with wide-spread tail and quivering wings much like 
a Water Thrush or Oven Bird and evidently with the hope of 
leading us away from the nest. Such a demonstration on the 
part of a tree-building Warbler is, I think, unusual. This n 
nest was fully 20 ft. above the ground near the end of a long, 
slender branch at least 10 ft. from the main stem of the tree, 
a solitary and not very vigorous young spruce growing under 
some large hemlocks and yellow birches which cast a dense 
shade over the spot. I photographed the nest which we took 
successfully by bending over another tree within reach.
