Appearance And Behavior

Costa’s hummingbird has a distinct look, with its iridescent pink and purple feathers along its back and wings. Its tail is long and pointed, making it easy to recognize in flight. An adult Costa’s hummingbird typically measures 3–4 inches from head to tail and weighs just 1/10 of an ounce.

These birds are active throughout the day but tend to be most active at dawn and dusk when temperatures are cooler. When they’re not foraging for food, they can often be seen defending their territories by chasing away other birds or aggressively fluffing up their feathers.

Habitat And Diet

The Costa Hummingbird lives in open woodlands, juniper scrubs, and desert areas with plenty of shrubbery and flowers. Found in hot, dry habitats like the Sonoran and Mojave deserts, these birds need to be able to find plenty of food sources in order to survive. Costa’s hummingbirds feed on nectar from flowers and catch small flying insects like mosquitoes, gnats, and fruit flies.

Mojave desert scrub, Sonoran desert, California coastal scrub, and lowland coniferous forests are all favorite habitats of Costa’s hummingbirds. Desert washes and chaparral are also important habitats for Costa’s hummingbirds, as these areas provide plenty of food sources and protection from predators.

Behavior & Life Cycle

Costa’s hummingbirds are monogamous birds and typically form strong, long-term bonds with their mates. They will often share nesting sites and defend their territory by chasing off any intruders. Female Costa’s hummingbirds will lay one to three eggs in a cup-shaped nest, which they build from spider silk, mosses, lichens, and grasses. The eggs incubate for about two weeks before hatching.

Once the chicks hatch, both parents take turns feeding them until they fledge at around 18 days old. At this point, they’ll be ready to leave the nest and explore their new surroundings, but they may stay close to their parents for up to four months before heading out on their own. To threaten intruding hummingbirds, male Costa will flash their colorful feathers and dive bomb them.

Lifespan Of Costa’s Hummingbird

The average lifespan of Costa’s hummingbird is about three to five years, but some individuals have been known to live up to nine years in the wild. These birds spend most of their time foraging for food and defending their territory, which can be a dangerous job at times. Fortunately, they have an excellent sense of speed and agility that helps them avoid predators.

Nesting Habits

In the spring and early summer, Costa’s hummingbirds build their cup-shaped nests in trees or shrubs to protect their eggs from predators. The female alone builds the nest from spider silk, mosses, lichens, and grasses and lines it with her own feathers for added insulation. She will lay one to three eggs that incubate for about two weeks before hatching. Both parents will help feed the chicks until they fledge around 18 days old.

Diet & Feeding Behavior

Costa’s hummingbirds mainly feed on the nectar of various flowers and insects for protein. They have an extraordinary ability to hover in one place as they forage for food, thanks to their rapidly beating wings. The birds also use their long beaks to reach deep into flowers for the sweetest nectar. During cold weather, Costa’s hummingbirds may migrate south or turn to artificial sources of food like hummingbird feeders.

Conservation Status

The Costa Hummingbird is listed as a species of least concern by the International Union for Conservation of Nature and Natural Resources (IUCN). Despite this designation, it’s considered vulnerable in some parts of its range due to threats from habitat destruction and climate change. Birders are encouraged to report any sightings of this species so that conservationists can better understand its population status.

Predators Of Costa’s Hummingbird

The average lifespan of Costa’s hummingbird is about two to three years. However, some individuals may live up to five or even six years in the wild. These birds face numerous predators, including Cooper’s hawks, great-horned owls, and western scrub jays. They also have to contend with human activities such as habitat destruction and urbanization.

Fortunately, Costa’s hummingbirds are resilient creatures that can adapt to changing conditions and still manage to survive in the wild—a testament to their beauty and strength.
