Ruby-throated Hummingbirds in New Brunswick

Ruby-throated Hummingbirds are summer residents in New Brunswick, arriving shortly before nesting begins in June 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 with Bay of Fundy and Gulf of St. Lawrence coastlines and extensive forest.

Across New Brunswick, ruby-throated hummingbirds typically nest from June–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.
