Wildlife of Portland, Oregon
Portland sits at the meeting point of the Willamette Valley, the Cascade foothills and the Columbia River, so the wildlife on offer runs from urban river otters and bald eagles to old-growth-forest species like the pileated woodpecker and Pacific tree frog. Forest Park alone holds more than 100 breeding bird species, and the Columbia Gorge just east funnels salmon, ospreys and returning warblers each spring.
Best timeApril – June for songbird migration, September – October for salmon runs and raptors.
- 1Forest Park is one of the largest urban forests in the US — 5,200 acres inside the city.
- 2Coyotes, bald eagles and beavers all breed within Portland city limits.
- 3The Willamette hosts one of the last urban chinook salmon runs on the West Coast.

Dos & don'ts
Local etiquette that keeps wildlife wild.
Do
- Leash dogs in Forest Park — off-leash dogs are the #1 wildlife disturbance.
- Turn off lights during spring migration nights.
- Keep distance — use zoom or binoculars, never bait animals closer.
- Stay on marked trails to avoid trampling nests, burrows and plants.
Don't
- Don't approach seal or sea-lion haul-outs on the Columbia.
- Don't pick native camas or trilliums — take photos instead.
- Never feed wildlife — human food changes behaviour and shortens lives.
- Don't share exact locations of nests, dens or rare species online.
