many other birds are very brightly coloured, in countless combinations. some of the most colourful birds are quite common, like pheasants, peacocks, domestic fowl and parrots. colourful small birds include blue tits, the goldfinches, hummingbirds, fairy wrens and bee eaters (which are also called rainbow birds). some birds, like those of the bird of paradise in papua new guinea have such beautiful feathers that they have been hunted for them.
