Honeyeaters Steal Fur from Sleeping Koalas for Their Nests
Even more surprising: the snoozing marsupials don't seem to mind.
Despite their cuddly appearance, koalas aren鈥檛 shy about using their sharp claws to defend their territory. (Ask .) But they seem to have made an exception for honeyeaters. When it鈥檚 nest-building time, this Australian family of birds likes to land on the slumbering marsupials, rip out their fur, and use it as insulation. And the koalas don鈥檛 mind a bit.
In what he claimed was the first documentation of the behavior, UCLA biologist Martin Cody described a 's harvest . 鈥淭he bird flew to perch on the koala鈥檚 head, neck or shoulders, plucked the hair vigorously from it, attending particularly to the longer hair on or around the ears,鈥 he wrote. It took the honeyeater about two minutes to gather up a good beakful. Then it flew back to its construction site, added the fur to the nest, and returned about five minutes later for another haul. 鈥淒uring these ministrations the koala was apparently unperturbed,鈥 Cody reported.
Birders have also noticed the interactions, which seem to only benefit one creature and mildly bemuse the other. Amateur photographer recently caught a loitering near a napping koala in southern Australia. The plucky bird finally zeroed in on its butt, waking the marsupial up in the process. But given that koalas can sleep for , it's hard to be mad at the hard-at-work honeyeater.

While you won't see it happening to a koala, you don鈥檛 have to travel Down Under to see this kind of bird behavior. If you鈥檙e in the Eastern United States, keep an eye out for Tufted Titmice next time your family dog takes an outdoor nap鈥攖hey鈥檝e been known to . Chipping Sparrows are even bolder: They'll yank hairs straight from a horse鈥檚 mane, 爆料公社's field editor Kenn Kaufman says.
People also need to remain on the lookout鈥攈oneyeaters and titmice have been known to on occasion. If it happens to you, take a cue from koalas and just keep calm. Oh, and be sure to get video.
