1 00:00:15,840 --> 00:00:17,880 Speaker 1: What's on the cutting room for today? Missus? Woots? 2 00:00:18,040 --> 00:00:19,000 Speaker 2: Do you like science? 3 00:00:19,480 --> 00:00:20,439 Speaker 1: I love science. 4 00:00:20,440 --> 00:00:22,960 Speaker 3: I used to love being in the science class, melting 5 00:00:23,000 --> 00:00:26,079 Speaker 3: stuff with buns and burners and the like, letting off 6 00:00:26,120 --> 00:00:27,320 Speaker 3: big egg gas things. 7 00:00:27,600 --> 00:00:30,840 Speaker 2: You're still good at that. Do you like science about animals? 8 00:00:31,680 --> 00:00:31,880 Speaker 1: Yes? 9 00:00:31,960 --> 00:00:35,720 Speaker 2: Sure, drill down even? Do you like science about birds? 10 00:00:36,600 --> 00:00:38,400 Speaker 1: We had to cut open a bird at school once, 11 00:00:38,479 --> 00:00:38,760 Speaker 1: did you? 12 00:00:39,040 --> 00:00:39,440 Speaker 2: Yeah? 13 00:00:39,560 --> 00:00:41,040 Speaker 1: I had a frog and a rat. 14 00:00:41,040 --> 00:00:42,240 Speaker 2: What kind of bird was it? 15 00:00:42,240 --> 00:00:44,320 Speaker 1: It was like I forgot what sort of bird it was? 16 00:00:44,520 --> 00:00:46,479 Speaker 1: It was a dead bird. We didn't have to kill it. 17 00:00:47,360 --> 00:00:50,519 Speaker 3: The years before at my school the kids had to 18 00:00:50,600 --> 00:00:52,920 Speaker 3: kill the frog and the rat. They'd had to actually 19 00:00:53,000 --> 00:00:55,520 Speaker 3: kill it and then dissect it and spring it out 20 00:00:55,560 --> 00:00:56,800 Speaker 3: on a little board. 21 00:00:57,040 --> 00:00:59,240 Speaker 2: Does it be? On two thousand I worked with a 22 00:00:59,280 --> 00:01:01,280 Speaker 2: cameraman used to rats as pets, and we were just 23 00:01:01,320 --> 00:01:03,200 Speaker 2: talking in a lab one day and he's got his 24 00:01:03,240 --> 00:01:05,640 Speaker 2: headphones on, and this guy in a lab coat was 25 00:01:05,680 --> 00:01:07,520 Speaker 2: preparing to be interviewed by us, and he just picked 26 00:01:07,520 --> 00:01:09,800 Speaker 2: out a rat and book bank the back, whack the 27 00:01:09,840 --> 00:01:11,280 Speaker 2: back of its head on a bench to kill it. 28 00:01:12,480 --> 00:01:16,120 Speaker 2: And this sounder course is going, well, it'll be like 29 00:01:16,200 --> 00:01:18,360 Speaker 2: us watching a dog being killed. They were his pets. 30 00:01:18,560 --> 00:01:21,280 Speaker 3: Yeah, although it's not out of character for a sound 31 00:01:21,360 --> 00:01:25,280 Speaker 3: recorders to be unusual, to be unusual and keep rats 32 00:01:25,319 --> 00:01:26,480 Speaker 3: like in the TV game. 33 00:01:26,680 --> 00:01:28,800 Speaker 2: In the Levy game, the soundercord is the one saying, 34 00:01:28,800 --> 00:01:29,679 Speaker 2: when are we having lunch? 35 00:01:29,760 --> 00:01:34,039 Speaker 3: Yep, always first for lunch, always first to just when 36 00:01:34,080 --> 00:01:36,679 Speaker 3: you're on a flow of doing something and everything's working well, 37 00:01:36,720 --> 00:01:38,679 Speaker 3: batteries of golde although I better check the. 38 00:01:38,640 --> 00:01:40,759 Speaker 1: Batches and may you've been sitting there twiddling your farms 39 00:01:40,760 --> 00:01:42,000 Speaker 1: for the last half an hour. 40 00:01:42,319 --> 00:01:46,000 Speaker 2: Yeah, when you do it, then that's them. But let's 41 00:01:46,000 --> 00:01:49,920 Speaker 2: talk about crows and not russell Crows can hold grudges 42 00:01:49,960 --> 00:01:52,800 Speaker 2: for up to seventeen years. This was what these people 43 00:01:52,880 --> 00:01:56,760 Speaker 2: have discovered. New research has shown that these birds and 44 00:01:56,800 --> 00:01:59,760 Speaker 2: crows apparently have long been considered the most intelligent of 45 00:01:59,800 --> 00:02:04,000 Speaker 2: the avian species. They're good at recognizing faces. So this 46 00:02:04,080 --> 00:02:07,160 Speaker 2: study imagine putting this study to the funding body. The 47 00:02:07,160 --> 00:02:10,680 Speaker 2: study began in two thousand and six Professor John Museloff, 48 00:02:10,760 --> 00:02:13,799 Speaker 2: an environmental scientist in the University of Washington. He put 49 00:02:13,840 --> 00:02:17,400 Speaker 2: on a scary mask and captured seven crows in a net. 50 00:02:18,280 --> 00:02:20,160 Speaker 2: So he captured seven crows Inday. 51 00:02:19,800 --> 00:02:21,000 Speaker 1: He's wearing a scary mask. 52 00:02:21,080 --> 00:02:23,760 Speaker 3: Yes, and he ran around with a big net by 53 00:02:23,840 --> 00:02:26,799 Speaker 3: the child snatchure in gg bang Bang, I. 54 00:02:26,800 --> 00:02:32,040 Speaker 2: Imagine Brendan Shaw. Then he released the birds unharmed, but 55 00:02:32,160 --> 00:02:36,040 Speaker 2: he put identification rings on their legs. He then had 56 00:02:36,160 --> 00:02:40,080 Speaker 2: He and his assistants would occasionally wear the mask in 57 00:02:40,160 --> 00:02:43,840 Speaker 2: subsequent years as they walked around campus, feeding the crows 58 00:02:43,919 --> 00:02:47,880 Speaker 2: and recording the reaction. On one occasion, he said he 59 00:02:47,919 --> 00:02:52,880 Speaker 2: was subjected to aggressive scowling cause caused caws noise from 60 00:02:52,919 --> 00:02:53,600 Speaker 2: these crows. 61 00:02:53,800 --> 00:02:57,519 Speaker 1: Not the cause was a successful family that sings from Ireland. 62 00:02:57,680 --> 00:03:01,440 Speaker 2: No, Brandon, it's this way you make science so hard. 63 00:03:01,919 --> 00:03:06,280 Speaker 2: He was subjected to aggressive noises from forty seven out 64 00:03:06,320 --> 00:03:09,600 Speaker 2: of the fifty three crows that he encountered. Now, considering 65 00:03:09,840 --> 00:03:12,080 Speaker 2: that that number of crows was so much higher than 66 00:03:12,080 --> 00:03:14,760 Speaker 2: the original number he captured in his so called scary mask, 67 00:03:15,560 --> 00:03:19,360 Speaker 2: this means that the crows learned to recognize the mask. 68 00:03:19,880 --> 00:03:23,240 Speaker 2: They learned to recognize threatening humans from their parents and 69 00:03:23,280 --> 00:03:27,760 Speaker 2: their relatives. This information was somehow passed on. 70 00:03:29,919 --> 00:03:31,720 Speaker 1: Wow, so the crows talk to each other? 71 00:03:32,040 --> 00:03:36,400 Speaker 2: Will they either talk to each other or giving birth? 72 00:03:36,600 --> 00:03:39,280 Speaker 2: They passed that knowledge on. I don't know. That's probably 73 00:03:39,280 --> 00:03:42,240 Speaker 2: what's being discussed. But you should know very well that 74 00:03:42,280 --> 00:03:44,760 Speaker 2: a bird can hold a grudge for seventeen years. Slide 75 00:03:44,800 --> 00:03:47,880 Speaker 2: your wife once. Oh she's not going to forget. They 76 00:03:47,880 --> 00:03:49,800 Speaker 2: don't even have to wear a scary mask. 77 00:03:51,720 --> 00:03:53,720 Speaker 3: I was thinking of the bird I'm looking at right 78 00:03:53,800 --> 00:03:57,120 Speaker 3: now that I've worked with for almost twenty. 79 00:03:56,960 --> 00:03:58,160 Speaker 2: Do you want to go cool? 80 00:03:59,440 --> 00:04:02,760 Speaker 3: And when I say cor, I'm not talking about any. 81 00:04:03,680 --> 00:04:04,840 Speaker 2: That's science for today. 82 00:04:06,960 --> 00:04:10,160 Speaker 1: Okay, kids, that's it for today. Come back tomorrow for more. 83 00:04:10,280 --> 00:04:12,280 Speaker 1: Jonesy and a Man is cutting room floor
