I have also noticed a lack of Chipmunks. I hiked around Chipman Hill
yesterday, and usually when you walk there, your travel is constantly marked
by their "chip" alarm call, but I only saw one.
Birds of note up the hill yesterday were Yellow Rumped Warbler, Pine
Warbler, Piliated Woodpecker, Norther Flicker, Eastern Phoebe,
White-Throated Sparrow, Brown-Headed Cowbird, Turkey Vulture, and all the
other usual suspects.
