Hummingbirds in Wyoming: the year at a glance
What makes Wyoming different
Wyoming's high elevation compresses the season into a short, intense summer. Broad-tailed Hummingbirds nest in the mountains, and their wing-trill is often heard before the bird is seen.

Ranges shift, and vagrants turn up well outside their expected territory — particularly in autumn and winter. If you see a hummingbird in Wyoming outside the windows above, it is worth reporting to your state ornithological society.
Getting your Wyoming feeder right
The recipe is the same everywhere: four parts water to one part plain white sugar. No red dye, no honey, no brown sugar. In Wyoming's warm months you will need to change the nectar every two to three days, and daily once daytime highs pass 88°F — fermented nectar and black mould make hummingbirds ill.
