December in the Violet-green 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 Violet-green Swallow specifically, December is a winter month of relative routine, with the species settled into its seasonal pattern across its range. Across the 16 states and provinces where violet-green swallows occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In December, violet-green 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

Violet-green swallows are not nesting in December. The season runs May–July at mid-latitudes.

That makes December a useful month for nest-box work: cleaning out old nesting material, checking mounts and predator guards, and making repairs while boxes are empty. A box that's ready early gets claimed early.
