And I have to admit, I'm not going to admit this is a zoologist, but very human. Like on I find that makes them all the more fascinating to me. Hey will craft his own drumstick. He'll snip off the branch and he'll whittle it down, step off all the bark and then he'll grasp it in his foot and he'll bang on the side of the tree. Hello, and he does it in a way that's really quite rhythmic. It's very unusual 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 thistles. The only case that we know where two of us made for the purposes of a sexual display, e you know. Yeah, 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 killing it at the X stage or the chick stage on on average, it was taking each female 10 years to produce one young Theo. Point of our paper was to sound the alarm bells and to say that this magnificent creature, northern rainforest, is in fact in peril, and the numbers are going down very, very quickly. But the mhm, they're very important for the ecosystem. They disperse the rainforest seats have these massive, great bigs and then the only creatures that could break into some of the largest seed pods. Okay, Uh huh, uh huh. It's quite a remote area, and people don't know about it, So I really love it. If people just knew what they had on their own soil on, if more people could get up there and see them and appreciate them, I'd be very, very happy about that.
