Barn Swallow in December
Where barn swallows are in December, whether they are nesting, and the best foods to offer right now.
December in the Barn Swallow'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 Barn Swallow specifically, December is a winter month of relative routine, with the species settled into its seasonal pattern across its range. Across the 61 states and provinces where barn swallows occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In December, barn swallows are absent in the South, mostly absent (migration only) across the mid-latitudes, and absent in the northern states and Canada. That north–south split is the defining feature of this month: where you live changes which version of this bird you're looking at.
Nesting in December
Barn swallows are not nesting in December. The season runs May–July at mid-latitudes.
Outside the nesting season, barn swallows put their energy into feeding and flocking rather than territory and young — which is exactly what makes them easier to watch and attract this month.
What to feed in December
- Winters in South America
Barn swallows nest on ledges under eaves and in barns; an open-front ledge shelf gives them a site.
Feeders are busiest at dawn and dusk as birds fuel up against long cold nights. Suet and other high-fat foods earn their keep this month.
