In Louisiana, tree swallows are a cold-season bird, arriving around November and heading back north to breed by February.

Month by month in this state
Highlighted months are when tree swallows are expected in Louisiana. 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 November is the time to act. Have feeders cleaned, filled and out by early November — the first tree swallows into Louisiana are scouting for reliable food, and a station that's ready early gets added to their route.
Through the winter, consistent food matters more than variety — birds map dependable stations into their daily routes and rely on them hardest during cold snaps.
