In Montana, varied thrushes are present through the warm months, arriving around May and heading south again by August.

These windows are set by latitude: Montana sits in the middle part of this species' range, so timing here runs later than the continental average — the season starts later this far north and the birds wait for it. In any given year, weather can move the first arrivals by a week or two either way.

Highlighted months are when varied thrushes are expected in Montana. 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 May is the time to act. Have feeders cleaned, filled and out by early May — the first varied thrushes into Montana 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.
