Birds 
swarm at 
Ball *s Hill 
Lincoln* s 
Finch 
Gray-cheeked Thrust, a very large bird, in nearly 
full song at 8 A. M., near the cabin. Song indistinguish¬ 
able from that of Bicknell's Thrush, so far as I could 
perceive. 
Birds literally swarming under the lee of Ball’s 
Hill all day, hundreds of Swallows and Swifts coursing 
back and forth close to the water or just over the tops of 
the trees; Thrushes, Warblers, Vireos, Flycatchers and 
Sparrows flitting among the thickets by the river or in 
the tops of the blossoming oaks on the hill-side. Most if 
not all of these birds were evidently the same individuals 
seen yesterday and some of them have been here since the 
first of the week, weather-bound. The Gray-cheeked 
Thrush may have been an arrival but I suspect that I caught 
a glimpse of it yesterday. The Canadian Warblers, Nelson’s 
Black-caps, Water Thrushes, White-throated Sparrows and 
Black-poll Warblers were in the same numbers and same 
places as yesterday. The Lincoln’s Finch at the cabin 
came to feed on the millet seed many times during the day 
and when not feeding was usually singing, I watched him 
a long time both yesterday and to-day and jotted down 
a number of notes which I shall write out in full after he 
has left us. I could not find the other bird which I saw 
yesterday near the farm.
