Ruby-throated Hummingbird in August

August feels like summer but the year has turned. Southbound migration is quietly underway, many adults are molting into fresh plumage, and family groups are breaking up. Late nesters are still feeding young in the North while southern birds are already drifting toward wintering grounds.

For the Ruby-throated Hummingbird specifically, August is a summer month inside the nesting season — one of the most active and demanding periods of this bird's year. Across the 44 states and provinces where ruby-throated hummingbirds occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

In August, ruby-throated hummingbirds are absent in the South, summer breeder 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.

August is inside the Ruby-throated Hummingbird nesting season — about a month earlier in the South and a month later in the North. Nest: walnut-sized cup of plant down bound with spider silk, saddled on a downward-sloping branch. Clutch 1–3 eggs (usually 2), incubation 12–14 days, 1–2 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 from tubular red and orange flowers
• Gnats, mosquitoes and small spiders

Change nectar every 2 days in hot weather (under 80°F, every 4–5 days) and clean the feeder each refill. Males defend feeders aggressively; several feeders out of sight of each other help.

Molting birds look scruffy and often skulk — don't be surprised if familiar visitors briefly vanish. Keep water fresh in the heat.

In August, 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.
