Palm cockatoo: Why a unique ‘drumming’ bird is in peril – BBC News

they're my favorite bird full stop i'm absolutely enthralled by them they are an amazing creature nothing like it in the animal world and i have to admit i'm not meant to admit this is a zoologist but i they're very human-like and i find that makes them all the more fascinating to me he will craft his own drumstick he'll snip off the branch and he'll whittle it down strip all off all the bark and then he'll grasp it in his foot and he'll bang on the side of the tree hollow and he does it in a way that's really quite rhythmic it's very unusual in the in the bird world or in the animal world because most of the time when animals make tools it's for the purposes of foraging they're finding things to eat this is the only case that we know of where a tool is made for the purposes of a sexual display the population we were studying has an extraordinarily low rate of reproduction it's the slowest we know of in the bird world the females only lay one egg in their clutch every two years at most that's normal that's natural but we found that that one egg had a very high chance of not making it so the predators were coming in and either killing it at the egg stage or the chick stage and on average it was taking each female 10 years to produce one young the point of our paper was to sound the alarm bells and to say that this magnificent creature in our northern rainforest is in fact in peril and the numbers are going down very very quickly they're very important for the ecosystem they disperse the rainforest seeds they have these massive great beaks and they're the only creatures that can break into some of the larger seed pods quite a remote area and people don't know about it so i'd really love it if people just knew what they had on their own soil and if more people could get up there and see them and appreciate them i'd be very very happy about that you
