Anna's Hummingbird (Calypte anna)

Who was Anna and how did she get a hummingbird with a metallic magenta crown and throat named after her? According to sources on the internet, she was a 19th century French aristocrat who befriended the herpetologist/ornithologist René Primevère Lesson. But does that really tell us anything? Enjoy the bird, readers. Life is but a dream written in running water.
