Rivoli’s Hummingbird Behavior
In the southern stretches of its range, the Rivoli’s Hummingbird socializes with other conspecific birds to the extent of crossbreeding with them. This means that the males can be highly territorial in other areas but nonterritorial in the southern stretches of its range.
They are trapliners as they follow a specific route while foraging for food. They feed on flower nectar by hovering and catch insects mid-air by dashing.
Rivoli’s Hummingbird Food
Rivoli’s Hummingbirds mainly sustain on floral nectar they extract from the variety of flowers
available in their habitats. Spiders and insects also form a small portion of their diet. These birds
have especially long bills which make it possible for them to extract nectar from longer flowers.
Rivoli’s Hummingbirds strategically feed on several patches of flowers so that the flowers get
enough time to rejuvenate. These birds might not allow certain smaller hummingbirds to feed on
the plants they like. Plants that Rivoli’s Hummingbirds commonly feed on are bouvardias, beard lip
penstemons, fuchsias, lion’s-ears, bellflowers, butterfly bushes, and columbines. Another source of
nutrition for them is the sugary water excreted by some insects.
Their main diet is nectar and insects. The young are mostly fed insects because nectar has no proteins. They also feed on sugar-water mixture from hummingbird feeders.
Rivoli’s Hummingbird Habitat
Rivoli’s Hummingbirds are commonly found in pine-oak forests in the mountains of the Southwest.
These birds can be found in elevations between 5,000-9,000 feet. Their elevations vary according

which have an abundant supply of flowers. Their nesting habitats are generally near streams.
Trees that are commonly used for nesting by these birds are Mexico stone pines, alligator junipers,
ponderosa pines, Arizona sycamores, Colorado white firs, Arizona walnuts, and Douglas-firs. In
colder weather, Rivoli’s Hummingbirds might come down to lower elevations.
The Rivoli’s Hummingbird is frequently found in the dry pine-oak forest. They live in riparian habitats in small mountain ranges and ravines of southern Arizona and New Mexico.

Rivoli’s Hummingbirds are large hummingbirds that have a breeding range that extends from the
mountains in the southwestern U.S. to Honduras and Nicaragua in Central America. These birds
migrate north during spring towards their breeding grounds. These grounds are usually located in
Arizona and New Mexico. Rivoli’s Hummingbirds are very widespread throughout its extensive
range. Although abundantly found, these birds are very secretive in nature, hence there isn’t a lot
of information about their migration.
