Ecology

The male blue-backed manakin has a fascinating breeding display, unusual in that it is a ''cooperative display'' rather than ''competitive''. Two males perch next to each other on a bare stick and jump up and down alternately, giving a buzzing call. When a female approaches, the perched bird moves backwards under the jumping bird, so the two perform a vertical circling movement. Groups of up to eight birds may perform together, with a different stick for each pair of displaying males. The female builds a twig nest in a tree; two brown-mottled white
