In Arizona, ospreys are present through the warm months, arriving around January and heading south again by July.
These windows are set by latitude: Arizona sits in the southern part of this species' range, so timing here runs earlier than the continental average — spring comes sooner, and the birds follow it. 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 Arizona. 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 January is the time to act. Have feeders cleaned, filled and out by early January — the first ospreys into Arizona are scouting for reliable food, and a station that's ready early gets added to their route.
Once nesting begins around February, 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.
Native plants that hold ospreys in Arizona
Food keeps a migrant for a day; habitat keeps it for the season. These Arizona-native plants are known to attract ospreys:
Summer fruit and one of the top caterpillar host trees.
Late-summer berry clusters taken by over 40 bird species.
Insect-rich in fall and seed in winter.
Dark summer fruit and heavy caterpillar load.
Seeds and bark insects; pygmy nuthatch and woodpecker habitat.
Acorns for jays and woodpeckers across the southern Rockies.
Late-season bloom supports insects; seed for sparrows.
Seed pods and insect-rich spring bloom.
