Using oil from a gland near their tail they groom their wings, abdomen, tail feathers and back. Stroke by stroke they tend to the veins of each feather. Hummers often groom their heads and necks with their feet, uses the front three claws like a comb. Sometimes they will groom their beak or neck by rubbing them against a twig. Sometimes a grooming hummer will grasp its bill and slide along it with its claws.
Hummers also take sunbaths, positioning their breast towards the sun and fluffing out.
They extend their neck and spread their tail. They may stretches one wing then the other, then lowers their head while stretching the wings upward. Sometimes a bathing hummer will throw its head back to toss droplets on its back. After bathing the bird will preen and dry its feathers. Hummingbirds also take shower baths while on the wing, and they sometimes sit in the rain on bare branch with feathers ruffled up so they can soak their skin.
