In Washington, ospreys are present through the warm months, arriving around February and heading south again by July.
These windows are set by latitude: Washington sits in the middle part of this species' range, so timing here tracks the continental average closely. In any given year, weather can move the first arrivals by a week or two either way.
Month by month in this state
Highlighted months are when ospreys are expected in Washington. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.
Getting ready before they arrive
The week before February is the time to act. Have feeders cleaned, filled and out by early February — the first ospreys into Washington are scouting for reliable food, and a station that's ready early gets added to their route.
Once nesting begins around March, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
What ospreys eat while they're here
- Fish of many kinds, 4–12 in long
Nests on poles, channel markers and purpose-built platforms; a platform near open water is often used.
