All data is from Skytop Lodge & Resort’s 5,500 acres, located in Monroe and Pike Counties, northeastern Pennsylvania. In most cases, the species noted represent their earliest seasonal records for each year (permanent resident, non-migratory birds such as woodpeckers and chickadees are mostly excluded except for occasionally noting their earliest singing/drumming and nesting activities of the season). Also noted are unusually late and/or off-season dates and large numbers, as well as sightings of uncommon species. The footprints made by various mammals in the snow (snowshoe hare, weasel, mink, otter, bobcat, coyote, etc.) were often seen in winter, but these are not included here.
