In Wyoming, fox sparrows are present through the warm months, arriving around May and heading south again by August.

Getting ready before they arrive
The week before May is the time to act. Have feeders cleaned, filled and out by early May — the first fox sparrows into Wyoming are scouting for reliable food, and a station that's ready early gets added to their route.
Once nesting begins around June, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
