Highlighted months are when ruby-throated hummingbirds are expected in Missouri. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.
Getting ready before they arrive
The week before April is the time to act. Have feeders cleaned, filled and out by early April — the first ruby-throated hummingbirds into Missouri are scouting for reliable food, and a station that's ready early gets added to their route.
Once nesting begins around May, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
What ruby-throated hummingbirds eat while they're here
- 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.
