In Arizona, yellow-billed cuckoos are present through the warm months, arriving around March and heading south again by September.

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.

Highlighted months are when yellow-billed cuckoos 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 March is the time to act. Have feeders cleaned, filled and out by early March — the first yellow-billed cuckoos into Arizona are scouting for reliable food, and a station that's ready early gets added to their route.

Once nesting begins around April, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.

What yellow-billed cuckoos eat while they're here

  • Tent caterpillars, cicadas, katydids and beetles

Called the 'rain crow' for calling before storms; one of few birds that eats hairy caterpillars in bulk.
