Birds Observed on Mt. Mansfield. 83 



spaces, and edges of clearings. Feeding young at foot of mount- 

 ain, June 30. 



52. Dendroica coronata. Myrtle Warbler. — As low down the 

 mountain as the "S" bend. Very numerous about the summit. 

 Often singing sitting on tips of firs and spruces. They had a pret- 

 ty habit of scouring along the edges of roofs of the hotel and barn, 

 and poising on wing to pick out spiders from under the eaves, the 

 outspread wings and hovering motion showing their rich coloring 

 to great advantage. Still in song there July 28. 



53. Dendroica maculosa. Magnolia Warbler. — Occasional on the 

 North Branch, but more often found in the pastures above the South 

 Branch, and always among the young spruces and firs. A few no- 

 ticed on the mountain road. 



54. Dendroica pensylvanica. Chestnut-sided Warbler. — Common 

 along the North Branch and shrubbery clearings of the mountain 

 toward the base. First found feeding young, July 8. The sexes 

 have different alarm notes. Verified for first time this year. 



55. Dendroica striata. Black-poll Warbler. — Abundant among 

 all the stunted spruces and firs from altitude of 3,000 feet to region 

 about the summit. Never heard them much north of the hotel. 

 The rhythmic beat of their notes never musical, but the impression 

 of ebb and Aovn' most agreeable. Feeding young, July 26. 



5G. Dendroica blackburnias. Blackburnian Warbler. — Ranging 

 with the hemlocks, but singing and feeding largely in the deciduous 

 trees — a habit I have noticed about Brattleboro. Common along 

 North Branch. 



57. Dendroica virens. Black-throated Green Warbler. — Common 

 along the North Branch. Well up the mountain. Found always 

 among the hemlocks. 



58. Seiurus aurocapillus. Oven-bird. — Abundant along North 

 Branch and mountain road wherever open deciduous woods abound. 

 Flight song June 11, then nightly till early in July. Feeding young- 

 July 11 (mountain road). July 6, male about Mr. Howell's orchard. 



59. Geothylpis pliiladelphia. Mourning Warbler.— Heard but a 

 few times at the foot of the mountain in the thickets and edge of 

 woodland. Mr. Howell reports them in the Notch. 



60. Geotliylpis trichas brachidactyla. Northern Yellow-throat. — 

 Abundant about streams at foot of plateau and North Branch. 



Gl. Sylvania canadensis. Canadian Warbler. — Nesting along 

 Nortii Branch. Common where timber had been cut and bushes 

 had grown up among the abundant tree-tops. 



62. Setophaga ruticilla. Redstart. — In the second growth timber 

 on Notch road almost to Bingham Falls. Also along the South 

 Branch and road from valley to Mr. Harlow's. Not abundant. Young 

 out of nest July 29. 



63. Galeoscoptes carolinensis. Catbird. — Common in the valley. 

 Observed almost to edge of mountain forest along the bushy streams 

 in the pasture.
