Description
Rainbow bee-eaters are brilliantly colored birds that grow to be 19-24cm (max 28cm) in length, including the elongated tail feathers. The upper back and wings are green in color, and the lower back and under-tail coverts are bright blue. The undersides of the wings and primary flight feathers are red and tipped with black, and the tail is black to deep violet. The rainbow bee-eater's two central tail feathers are longer than the other tail feathers, and are longer in the male rainbow bee-eaters than in the females. The crown of the head, the stomach and breast, and the throat are pale yellowish in color, and the rainbow bee-eater has a black bib and a black stripe through its red eye.Distribution and habitat

Behaviour
Like all bee-eaters, rainbow bee-eaters are very social birds. When they are not breeding they roost together in large groups in dense undergrowth or large trees.Nesting
Breeding season is before and after the rainy season in the north, and from November to January in the south. Rainbow bee-eaters are believed to mate for life. The male will bring the female insects while she digs the burrow that will be their nest. The bee-eater digs its burrow by balancing on its wings and feet, and digs with its bill, then pushing loose soil backwards with its feet while balancing on its bill. The female bee-eater can dig about three inches down every day. The nest tunnel is very narrow, and the birds' bodies press so tightly against the tunnel walls that when the birds enter and exit their movement acts like a piston, pumping in fresh air and pushing out stale air. Rainbow bee-eaters have also been known to share their nest tunnels with other bee-eaters and sometimes even other species of birds. The female lays between 3 and 7 glossy white eggs, which are incubated for about 24 days until hatching. The young bee-eaters fledge after about 30 days and are fed by both parents, as well as any older bee-eaters that may not have paired off or have lost their mate. Cane ToadCane Toad
