On mild winter nights in mid-January, Pacific tree frogs (Pseudacris regilla) begin their breeding calls from wetlands, ponds, and temporary pools across the Pacific Northwest. These small frogs, typically only 1-2 inches long, produce surprisingly loud "ribbit" calls that carry across the landscape, marking one of the earliest signs of approaching spring. Males call from shallow water edges, often in large choruses that create a cacophony of sound on nights when temperatures rise above 45°F. Though they breed primarily in spring, these hopeful winter vocalizations occur during warm breaks in the weather, demonstrating the species' adaptability and eagerness to reproduce.

Mid-to-late January continues winter's storage crop abundance—root vegetables (beets, carrots, parsnips, turnips), hardy brassicas (kale, Brussels sprouts, cauliflower), and storage alliums (garlic, leeks, onions). Winter squash and apples from fall harvest remain plentiful at winter farmers markets.

Listen for Pacific tree frog choruses on mild winter nights (above 45°F) near wetlands, ponds, and temporary pools—January marks the beginning of their breeding season with males creating loud "ribbit" calls. Visit wetland trails like Magnuson Park in Seattle or Washington Park Arboretum's Waterfront Trail for winter nature walks where frog calls can be heard.
