The beautiful iridescent colors of an Anna's hummingbird (Calypte anna)
I spotted this beautiful birds in the Coronado Tidelands PK near San Diego. I was absolutely fascinated by the iridescent colors. The sexes show a clear dimorphism in the coloration of their plumage. I was very happy that I was able to photograph both sexes.
And another little fun fact (translated from the german wikipedia): In relation to their body size, Anna's hummingbirds are probably the fastest vertebrates in the world. During their courtship flights, the animals reach speeds of 385 body lengths per second (equivalent to 27.3 m/s or 98.28 km/h) with acceleration values of around ten times the acceleration due to gravity. For comparison: Peregrine falcons can reach speeds of up to 200 body lengths per second in a dive, while fighter jets such as the MiG-25 (a Mach 3 interceptor) can only reach a maximum of around 40 times their total length.
