There was one new comer, however, viz: a Great- 
crested Flycatcher, the first I have ever seen at Ball’s 
Hill. It was flitting about in the tops of some young 
oaks near the river path about 100 yards west of the cabin 
and was silent and unusually tame and sluggish. 
Visited Davis’s Hill twice during the day and found 
a great many birds there: Water Thrushes, Canadian Warblers, 
Wilson’s Black-caps, Peabody birds, Cat-birds, Wilson’s 
Thrushes and a. female Towhee in the thickets by the river; 
in the large trees on the crest of the ridge two Yellow- 
throated Vireos (males, singing), two Least Flycatchers, 
a, Blackburnian Warbler, a Pine Warbler, a Black-throated 
Green, a Humming-bird and a Cedar Bird. 
In Prescott’s Pines I heard another Blackburnian 
but almost nothing else save the omnipresent Oven-birds, 
Chestnut-sided Warblers, Redstarts , etc. 
Saw two pairs of Rose-breasted Grosbeaks this 
morning, one near the cabin, the other on the river slope 
of the Blakeman woods. Both females were collecting buildirg 
material and I saw the Blakeman Hill bird go to the nest 
which was in the top of a tall on the hillside 
about 40 yards from the river. The males followed their 
mates closely but received no assistance whatever. Neither 
sang, but both kept up a low, tender call ( woi- e, woi- e 
or woi- e-e.) which was also occasionally given by the females. 
The female at the cabin was collecting dry grass at the river
