Ruby-throated Hummingbirds in Missouri

Ruby-throated Hummingbirds are summer residents in Missouri, arriving shortly before nesting begins in May and leaving after the young are independent. Through the season they feed on nectar from tubular red and orange flowers; gnats, mosquitoes and small spiders.

Humid continental, from the Ozark Plateau in the south to prairie and river floodplains in the north.

Across Missouri, ruby-throated hummingbirds typically nest from May–August. Nest site: walnut-sized cup of plant down bound with spider silk, saddled on a downward-sloping branch. Females lay 1–3 eggs (usually 2), incubate for 12–14 days, and young leave the nest after 18–22 days.

Hot, humid summers.

• Ruby-throated Hummingbirds don't use nest boxes. Keep dense native shrubs and trees such as trumpet honeysuckle, trumpet creeper, red buckeye for nest sites.
• Delay heavy pruning of shrubs until after August.

Of the regional native plants we track for Missouri, these 5 provide food or cover ruby-throated hummingbirds use:
