On a small island in the middle of a reservoir in south India, thousands of river terns gather each summer to breed. Competition for mates is intense and single males regularly try to break up courting couples. Here a male tries to interrupt a mating pair.
It is amazing just how vivid and bright the color of their feet is!
Do the feet only turn that super-vivid color during mating season, or are they like that all year long?
Their bills are also uncommonly vivid. I also wonder - is just a breeding season thing, or a year-around thing?
