moss, as we were unable to detect it, although the bird was plentiful. 

 It has a very pretty song. 



28. Dendroeca castanea Baird. Bay-breasted Warbler. 



Most abundant of the Sylvicolidce at Umbagog. Breeds. Ob- 

 served only in spring at Quebec (Couper) . Seen rather rarely in 

 spring at Hamilton (Mclllwraith) . Very rare at Norway ( Verrill) . 

 Two nests of this species were taken at Umbagog on June 8th. The 

 tree selected by the birds belonging to the first nest discovered, as a 

 summer home, stood by the side of a cart-path in the woods. My at- 

 tention was attracted to it while walking along, by seeing the female 

 fly into the tree and alight on the nest which was then (June 3d) but 

 just completed. It was placed on the horizontal branch of a hem- 

 lock twenty feet from the ground, and five or six feet from the trunk 

 of the tree. On June 8th the nest was taken, and then contained 

 three fresh eggs. The second nest was found by Mr. Brewster who, 

 having shot a female that exhibited signs of nesting, searched for the 

 nest, and discovered it in a hemlock tree on the side of a thickly 

 wooded hill. This nest contained only two fresh eggs. It was like- 

 wise placed on a horizontal branch about fifteen feet from the ground. 

 The nests are both large for so small a bird, and resemble that of 

 the .Purple Finch. The first one is composed outwardly of fine, dead 

 twigs, from the larch, among which are scattered a little of the long 

 tree-moss. It is very smoothly and neatly lined with black, fibrous 

 roots, the seed stalks of a species of ground moss, a few hairs of 

 Lepus Americana, and a single piece of green moss that grows in 

 damp woods. The dimensions are ; diameter externally, six inches; 

 internally, three inches ; depth, externally, two and one-half inches; 

 internally, one and one-fourth. It contained three eggs, of which the 

 following is a description : No. 1 is bluish green, thickly spotted 

 with brown over the entire surface, with a ring of nearly confluent 

 blotches of brown and lilac at the larger end. The dimensions are: 

 71 X 53. 1 No. 2 resembles No. 1, with the exception that there are 

 some amber spots in the ring around the larger end, and the smaller 

 end is immaculate. Dimensions, 65 X 50. No. 3 is less spotted than 

 the others, and has a few brown lines on the larger end. Dimen- 

 sions, 70 X 50. No. 1 is the most perfect in form. No. 2 rather 

 rounder, while No. 3 is long for the width. The second nest also 

 resembles the first, but contains a few stalks of grass near the centre.
