I have a number of regular hiking-birding routes. One is on Tussey Mt, from Jo Hayes vista to PA Furnace Rd with a side excursion down to Indian Steps Trail and back up, for 7 unique miles, plus 3 miles back.
What I have found especially interesting during late April-July is the number of black-throated green warblers I encounter there. On 6 walks there during the last 3 years, I have counted 51-59 singing male BTG warblers (56 yesterday). Their density on the ridge top is much higher than on the lower slopes. Most of the ridge top is deciduous forest - it doesn't seem to matter whether or not there are hemlocks.
I find the same thing on Stone Mt and Jackson Trail (other side of rt 26), though not as many BTGs.
Also lots of red-eyed vireos (122 yesterday) and ovenbirds (82 yesterday). Also a mourning warbler yesterday, a variant with a white eye ring. About half the time in summer, a rattlesnake or two.
