The Iowa season
Ruby-throateds follow the Mississippi and Missouri river corridors into Iowa in late April. The wooded northeast Driftless region holds the state's densest breeding population; open farm country sees birds mainly as garden visitors in migration.
The two-week head start matters more than it looks: the first migrants arrive before most nectar flowers open, and a reliable feeder can anchor a male's breeding territory in your yard for the whole summer. At the other end, keep the feeder up until late october — southbound stragglers, often the year's young, are the birds that need it most.

Nectar calculatorFrequently asked questions
When should I put out hummingbird feeders in Iowa?
Have feeders out by April 10 — about two weeks before the first birds typically arrive (late April to early May). The vanguard males travel ahead of the main wave, and an early feeder helps them refuel when few flowers are blooming.
When should I take down hummingbird feeders in Iowa?
late October. And don't worry about tempting birds to stay too long: migration is triggered by day length, not food. A full feeder will never stop a hummingbird from leaving — it simply fuels late stragglers, which need the help most.
Do hummingbirds stay in Iowa year-round?
No — Iowa's hummingbirds head south for the winter, with the last birds typically gone by early October. If you see a hummingbird at a feeder in late fall or winter, look closely: it may be a rare western visitor such as a Rufous Hummingbird, worth reporting to your local birding group.
What should I put in the feeder?
Plain white sugar and water at a 4:1 ratio — 1 cup of sugar per 4 cups of water. Never use honey, brown sugar, or red dye. Our nectar calculator scales the recipe to any feeder size.
