Anna's Hummingbird in May

May is the peak of the birding year. Migration floods the North, dawn chorus is at its loudest, and nesting is underway across most of the continent. By month's end the first broods of the year are hatching in mid-latitudes.

For the Anna's Hummingbird specifically, May is a spring month inside the nesting season — one of the most active and demanding periods of this bird's year. Across the 8 states and provinces where Anna's hummingbirds occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

absent

In May, Anna's hummingbirds are absent in the South, year-round resident across the mid-latitudes, and absent in the northern states and Canada. That north–south split is the defining feature of this month: where you live changes which version of this bird you're looking at.

May is inside the Anna's Hummingbird nesting season — about a month earlier in the South and a month later in the North. Nest: tiny cup of plant down and spider silk. Clutch 2 eggs, incubation 14–19 days, 2–3 per season.

The southern nesting season has already wound down, but northern pairs are still raising young — the whole season shifts later as you go north. During the nesting months, adults switch to protein-rich foods for their young, become more secretive around the nest site, and often visit feeders in quick, purposeful trips rather than lingering.

• Nectar and gnats

Anna's stay year-round and nest in winter; in freezing weather, keep one feeder thawed.

Adults feeding nestlings need easy calories. Some species that ignored feeders all winter now visit regularly, and you may see fledglings brought to feeders by their parents.

In May, the best watching is around food rather than the nest — adults make repeated foraging trips and are most visible at dawn and dusk. Give nesting birds space: if a bird is carrying food or scolding you persistently, you're close to a nest and should back off.
