The Plush-crested jay is an unusually colorful corvid with its odd rounded black tuft (which gives it its name), yellow eyes and a bright blue eyebrow line. It is found in an undulating belt from central South America to the southeast of the continent. This one appeared just a few meters from the world's largest waterfall, Cataratas de Iguazú, and seemed to be looking at me a little curiously. Plush-crested jays are omnivores. They mainly eat seeds, nuts, insects and small invertebrates. Sometimes they supplement this diet with fruit or corn. Depending on the food supply, they also take the eggs of other birds and sometimes small animals such as frogs or snakes. They build nests, reminiscent of European magpie nests, in trees. Research has shown that relatives help each other raise their young.
