The Wyoming season
Broad-tailed trills fill Wyoming's aspen and pine country from May; Calliope breed in the northwest ranges near Yellowstone. When the Rufous tide arrives in mid-July, high-country feeders from Jackson to the Bighorns turn into contested airspace until Labor Day.
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 early 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 Wyoming?
Have feeders out by April 15 — about two weeks before the first birds typically arrive (late April to mid-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 Wyoming?
early 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 Wyoming year-round?
No — Wyoming's hummingbirds head south for the winter, with the last birds typically gone by mid-September. 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.
