Wildlife near Portland, Oregon

Illustrated wildlife of Portland

Portland tucks a surprising amount of wild country inside the city, from Forest Park, one of the largest urban forests in the country, to the wetlands where the Willamette meets the Columbia. Great blue herons (the official city bird) stand in every backwater, bald eagles and ospreys fish the rivers, and beavers work the smaller creeks. Vaux’s swifts put on the city’s best show each September, funneling by the thousands into the Chapman School chimney at dusk.

Built from recent research-grade iNaturalist observations. Identifications are community-sourced and may occasionally be wrong, and the ranking reflects where people record and photograph wildlife, so a species seen often here is not necessarily rare elsewhere. Some plants and animals are only out in certain seasons. Treat this as a lively snapshot of what people are finding, not a formal checklist.
