Not a caterpillar - On a frosty May morning, a group of European Bee-eaters perched on a branch gave the impression of a caterpillar at first glance. The vibrant colours of their feathers, with shades of green, blue, and yellow, seemed to blend together and create a fluffy, caterpillar-like appearance. It's also a winning image in Adult Category of European Wild Wonders photo competition, November 2011. José Luis Rodríguez
@trinsec it’s a real optical illusion isn’t it, yes it’s a brilliant photograph.
