Many species of birds practice monogamy in some form or other. They perform dances, present each other with gifts, often care for their offspring together, and sometimes even mate for life.
Why do birds have such bright colours and dramatic mating displays? Take the lilac-breasted roller, a bird with bright purple plumage and electric blue under their wings, who fly high in looping circles before tipping backwards in the sky and stalling their flight, resulting in backward rolls through the air.
The ten species with the sharpest observed population declines in the last 25 years, and although some you may never have seen before, others may surprise you. If action to stop these declines isn’t taken soon, we may lose wildlife wonders such as starling murmurations and the haunting cuckoo call.
