Long Female Hummingbirds
Female hummingbirds don flashy feathers to avoid being bothered by other hummingbirds. They tend to have bright blue heads and throats. But mate choice doesn't seem to drive these females pretty plumage since males don't appear to prefer the blue females. Therefore, bright colors may help lady birds blend in with the guys, and as a result, feed for longer.
