December in the Swamp Sparrow's year
December is the start of the true winter season. Birds are settled into winter ranges and flocking behavior peaks — mixed flocks move through woods and yards together, and feeding stations become social hubs. Short days mean birds must find most of their food in a few hours of daylight.
For the Swamp Sparrow specifically, December is a winter month of relative routine, with the species settled into its seasonal pattern across its range. Across the 46 states and provinces where swamp sparrows occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.
