iS87-l Chadbourne on the Summer Birds of the White Mts. 103 



Above the timber line this growth extends fur a varying distance 

 up the mountain enclosing rocky islands and promentories, where 

 all of the common alpine plants are abundant. 



The only birds found here are Juncos, Black-poll Warblers, 

 and a few Yellovv-rumped Warblers, Bicknell's Thrushes, and 

 White-throated Sparrows; while on the bare lichen-covered 

 rocks above nothing grows except the hardy alpine plants, shrubs, 

 and grasses, and the common Junco is the only bird found, unless 

 a solitary Black-poll Warbler or White-throated Sparrow has 

 strayed up from the dwarf spruces below. From the timber line 

 to the very top of the mountain the Junco continues in only 

 slightly diminished numbers and for the last quarter of the road 

 is usually the only bird seen. 



The following birds are found from the base to the timber line 

 and vary but little in abundance with an increase of altitude, if 

 the surroundings are equally favorable : Ruffed Grouse (Yel- 

 low-bellied Flycatcher?), Blue Jay, Canada Jay, White-throated 

 Sparrow, Purple Finch, Yellow-rumped Warbler, Bay-breasted 

 Warbler, Blackburnian Warbler, Winter Wren, and Golden- 

 crowned Kinglet. 



1. Actitis macularia. Shotted Sandpiper. — One was seen on July 8, 

 18S6, in the Great Gulf on the West Branch of the Peabody River. It 

 was only a short distance below our camp and at an altitude of about 3100 

 feet. 



2. Dendragapus canadensis. Canada Grouse. — On July 3, 1S86, one 

 ran across the carriage road just in front of J. L. Goodale as he was walk- 

 ing up from the base of the mountain. Altitude about 3500 feet. No 

 others seen. 



3. Bonasa umbellus. Ruffed Grouse. — Extends from the country 

 at the base of the range to the tree limit. A female and brood of young 

 found in the stunted birches near the Half-way House (altitude, 3S40 feet) 

 on July 26, 1S84; and another brood was seen near the timber line on Mt. 

 Adams on Sept. 2, 1SS4. Strange to say. none were seen by any of the 

 party in 1SS6.
