The Anna’s hummingbird (Calypte anna) is a small hummingbird found in western North America. It is named after Anna Massena, the Duchess of Rivoli, who collected the first specimen in California in 1839. Anna’s hummingbirds are known for their iridescent feathers, which can change color depending on the angle of light. This iridescence is caused by the way light interacts with the microscopic structures on the feathers.
The Anna’s hummingbird is an important pollinator of many plants, including wildflowers, fruits, and vegetables. It is also a popular bird with birdwatchers due to its beauty and tameness. Anna’s hummingbirds are found in a variety of habitats, including forests, woodlands, meadows, and gardens. They are most common in areas with plenty of flowers and other sources of food.
