683 a. LONG-TAILED CHAT, Icteria virens longicauda 



(Lawr.) 



This western form of the chat was abundant in the bushy 

 localities near the Jocko River at Selish. Apparently the nest- 

 ing season was just beginning, June 16, as the males were in 

 full song and persistently voluble; but though the bushes were 

 thoroughly searched, nothing was found but structures in the 

 first stages of erection. 



685. WILSON'S WARBLER, Sylvania pusilla (Wils.) 



This warbler, regularly making its summer home north of 

 the United States, sometimes lingers in the Boeky Mountain 

 regions along its northward course, and rears its brood within 

 our borders. One note was made of its occurrence along our 

 itinerary, where it was found nesting at McDonald Lake, June 

 24, 1901. 



687. AMERICAN REDSTART, Setophaga ruticilla (Linn.) 



Abundant in all suitable localities near the Station. In June 

 it was found nesting in numbers in the swamp woods be- 

 tween Swan Biver and Flathead Biver. Not frequently ob- 

 served in the higher woods. Its songs were heard until the 

 middle of August. 



This species occurs commonly in the trees and shrubbery 

 along the streamsides. We found it abundant at the foot 

 of Flathead Lake, frequenting the haw groves and willows. 



701. AMERICAN DIPPER, Cinclus mexicanus Swains. 



Along the dashing waters of the falls above Sin-yale-a-min 

 Lake the American dipper finds a congenial home. Its dark 

 gray attire is quite in harmony with the rocks upon which it 

 stands in the midst of the roaring rapids, as well as the sombre 

 light of the thick forests which surround its chosen domains. 

 Though we searched diligently among the rocks along the 

 falls, we were unable to find a nest. The American diper was 

 also observed along the outlet of the lake, where the little 

 stream dashes among the boulders on its way down the ravine. 

 We also noted it at the outlet of Lake McDonald. 



The American dipper occurs not uncommonly along Swan 

 River, between the head of the rapids and the mouth. Very 

 likely breeds, as it was observed both in June and August.
