When to Put Out (and Take Down) Hummingbird Feeders in Arizona

In Arizona, put hummingbird feeders out around late February and take them down around early November. The first arrivals typically show up in the second week of March and most are gone by mid October. The Anna's Hummingbird stays all year, so leave one feeder up for it.

First arrivalsMar 8-14

Take feeders downNov 1-7

Rule used: feeders go out two weeks before the typical first-arrival week and come down two weeks after the last week birds are still reported. First arrival is the first week reports reach 10% of the species' usual in-season rate; last seen is the last such week. A few early or late birds can fall outside.
