In California, lark sparrows are present through the warm months, arriving around February and heading south again by August.

These windows are set by latitude: California 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 lark sparrows are expected in California. 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 lark sparrows into California 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.
