- March–September
In Arizona, varied buntings 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.
Month by month in this state
Highlighted months are when varied buntings 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 varied buntings 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 varied buntings eat while they're here

A Mexican border specialty of thorny canyon scrub; a birdbath is the best way to see one.
