42 Philipp and Bowdish, New Brunswick Birds. [jan. 



Euphagus carolinus. Rusty Blackbird. — A nest with five young, 

 two or three days old, was found June 13, 1917. It was built about four 

 feet from the ground, in a scrubby spruce, in scanty growth of spruce and 

 tamarack, in boggy ground. Exteriorly it was composed of scrubby spruce 

 twigs, with a little usnea moss in the foundation, and lined with dry grass, 

 some of which retained green color. The female was brooding when the nest 

 was found, and remained on the nest until approached within three feet. 

 It was evident that several pairs of birds were breeding in the general 

 vicinity, as was also the case in 1918. 



Spinus pinus. Pine Siskin. — Nesting was just commencing at the 

 close of our 1918 visit. One nest contained three eggs on July 1, and two 

 others were just being completed. 



$ Melospiza lincolni lincolni. Lincoln's Sparrow. — More common 

 than our earlier experience indicated. In 1917 six nests with four eggs 

 each were located, June 14, 16, 18, 19, 20 and 27. In 1918 a nest with 

 four and another with five eggs were located, June 11, and another with 

 five eggs, June 12. 



Vireosylva philadelphica. Philadelphia Vireo. — In the abnormal 

 season of 1917, no signs of nesting by these birds were noted on a visit on 

 June 14, to the locality where they were found in 1916, though two or three 

 of the birds were observed. In 1918, however, six additional nests, five 

 containing four eggs each, and the sixth three (which was apparently the 

 full laying), were located. These corresponded closely with the nests 

 found in 1916, as to locality, situation and material, the dates, however, 

 averaging a little later, two nests containing fresh eggs as late as June 27. 



Vermivora peregrina. Tennessee Warbler. — The seasons of 1917 

 and 1918 considerably amplified our experience with the breeding of these 

 birds. In 1917 nine nests with complete layings of eggs were examined, 

 as follows: June 23, five eggs; June 25, six eggs; June 27, two nests with 

 six eggs each; June 29, two nests with six eggs each; June 30, five eggs, 

 seven eggs; July 2, six eggs. The first nest found in 1918 was June 16, 

 six slightly incubated eggs, another on the same date containing five. 

 Nests with partially incubated eggs were found as late as June 30, on which 

 date, also, the second nest containing young was noted, eggs previously 

 found having hatched by June 29. In 1918 no less than thirty-four nests 

 were found. Of these three were either deserted or not visited later; one 

 contained only three eggs, which the bird assiduously incubated; one 

 contained four eggs; eight contained five eggs each; eighteen contained 

 six eggs each; three contained seven eggs each. 



The experience of the past two years has demonstrated that while the 

 boggy ground nesting, previously described, is the really typical and by 

 far the most common form, not a few of these birds nest on higher and 

 dryer ground. One such nest, found June 24, 1918, was well up on a steep 

 hillside, in rather open woods, on fairly dry ground, utterly devoid of moss 

 and grass cover. It was built among a thick growth of dwarf dogwood, 

 and under a tiny, crooked stemmed maple sapling, very well concealed,
