Observations at feeder in Massachusetts and the surrounding area.
Time: 12pm-1:30pm
Date: March 1st 2020
Location: Stow, MA on the edge of state conservation land.
Weather: Sunny with few fluffy clouds and light wind, in the low 30s during the day.
Habitat: Suet and seed feeders in backyard that backs on conservation land. About 30 feet from the edge of a mixed wood forest. Pond and streams nearby, as well as good edge habitat.
Many of these birds were visibly puffed up to protect from the cold of the day, especially since it had been warm around this time and this day was an exception. Many of them were arriving at the feeder in groups, and seemed to spend most of their time foraging at the feeders or on the ground where it was clear of snow banks.
For the woodpeckers, in warmer months they probably would not be seen frequently at feeder like this as there would be more bugs in the trees for them to have access too. Same with some of the smaller oscines who will eat bugs/worms in the warmer months, and maybe natural seeds/berries in the spring and fall, but in the winter they appreciate the supplement that the feeders provide.
The hawks would probably overnight in lower branches, this would allow them to have a clearer view of small rodents that may be nocturnal or crepuscular. The nuthatch and the woodpeckers may commonly use holes in dead stands at various heights. The small oscines may congregate together in groups to maintain warmth at night, they may choose to be further into the forest and at mid-high height to limit the wind that would hit them over night.
