72 Microseasons of the Pacific Northwest

Late December brings peak winter bird diversity to Pacific Northwest backyards and forests, with the region paradoxically hosting more bird species in winter than summer. Varied thrush descend from mountain breeding grounds to lowland parks and gardens, their distinctive orange-and-black plumage brightening gray winter days as they forage through leaf litter with characteristic backward-hopping movements. Dark-eyed juncos (Oregon variety with dark hoods and rufous sides) arrive in flocks, joining year-round residents like chestnut-backed chickadees, Pacific wrens, and song sparrows. Winter storms and cold weather concentrate birds at feeders, creating exceptional viewing opportunities. The Pacific Northwest serves as a winter refuge for northern-breeding raptors and waterbirds seeking milder conditions, while resident species remain active throughout the season. Varied thrush switch from summer insects to winter berries and seeds, often visiting ground feeders and foraging in areas where fruit-bearing shrubs provide abundant food. This period marks the full establishment of winter bird communities that will remain through February.

Holiday feasts feature Pacific Northwest abundance—roasted root vegetables (carrots, parsnips, rutabagas), hearty cruciferous vegetables (Brussels sprouts, cabbage), and stored winter squash. Christmas markets offer mulled wine, raclette, and regional specialties celebrating the season.

Participate in the Christmas Bird Count (Dec 14 - Jan 5), North America's longest-running citizen science project, counting winter birds across the Pacific Northwest. Set up backyard feeders with black oil sunflower seeds to attract diverse winter species including varied thrush, juncos, and chickadees during peak gathering season.
