Spinus pinus.
Maine (Lake Umbagog).
1874.
Aug. 5 A large flock feeding in a birch, with two Red Crossbills. Shooting one of the Pine Finches I found it was long past the breeding season. Unlike last season I seldom see or hear these birds near the Lake House, and the few met with elsewhere have the habits of the species in autumn.
1876.
June 1. We see them daily in small flocks.
(June 11)
They have become abundant within the last few days, coming about the house in little companies. We have not heard them singing yet.
" 19. Daily becoming more abundant; I heard the males singing this morning. The song is strikingly like that of Chrysomitris tristis but perfectly distinguishable and decidedly inferior. These birds are now exclusively in pairs.
1879.
June 19. Very scarce this season. A few noted daily during the first part of my stay, but of late I see them very rarely.
" 21. A single bird alighted in the road on the Sargent place.
1880.
May 19. Alva Coolidge called my attention to one of these birds, remarking that they equally common with the Crossbills about the logging camps in winter. I now see or hear them daily.
Sept. 2. Very numerous about the house where great flocks come to feed in the paper birch. When there is no wind nearly every bush and twig of foliage soon is trembling with their movements.
" 13. Not nearly as common as at the time of my arrival.
1882.
Oct. 8-22 Common during our entire stay but not as abundant as usual; in small flocks feeding on the birch seeds.
