Juvenile. Sulawesi, Indonesia. This bird breeds in Australia and Papua New Guinea and migrates north-west into Indonesia. A locally common non-breeding visitor throughout Wallacea and West Papua; rare on Bali.
Rainbow bee-eaters mostly eat flying insects, but, as their name implies, they have a real taste for bees. Even though rainbow bee-eaters are actually immune to the stings of bees and wasps, upon capturing a bee they will rub the insect's stinger against their perch to remove it, closing their eyes to avoid being squirted with poison from the ruptured poison sac. Bee-eaters can eat several hundred bees a day, so they are obviously resented by beekeepers, but their damage is generally balanced by their role in keeping pest insects such as locusts, hornets, and wasps under control.
