1 00:00:03,060 --> 00:00:22,820 Here we go again. This time we are going to talk about the birds. That is the second group of vertebrate animals that we are going to study. And as we did before, I want you to get ready. Page 47. Finger ready. Everyone is ready. Yes. 2 00:00:22,820 --> 00:00:28,339 I'm going to vertebrate birds and we are going to start reading. 3 00:00:28,780 --> 00:00:32,560 One, two, three. Here we go. 4 00:00:34,000 --> 00:00:37,240 There are thousands of types of birds. 5 00:00:38,259 --> 00:00:41,020 Birds come in all shapes and sizes. 6 00:00:42,740 --> 00:00:43,619 Reproduction 7 00:00:43,619 --> 00:00:46,619 Birds are aviparous. 8 00:00:47,439 --> 00:00:49,539 This means they lay eggs. 9 00:00:49,539 --> 00:00:57,340 They incubate the eggs by sitting on them to keep them warm while the baby grows inside. 10 00:00:58,780 --> 00:00:59,420 Nutrition 11 00:00:59,420 --> 00:01:04,959 Birds can be carnivores, herbivores or omnivores. 12 00:01:06,219 --> 00:01:07,719 Birds have beaks. 13 00:01:08,680 --> 00:01:13,200 They have different types of beaks depending on the food they eat. 14 00:01:13,200 --> 00:01:22,019 Adult birds find food for their babies until the babies can find their own food. 15 00:01:23,939 --> 00:01:24,780 Respiration 16 00:01:24,780 --> 00:01:28,579 Birds breathe with their lungs. 17 00:01:30,640 --> 00:01:32,079 Physical characteristics 18 00:01:32,079 --> 00:01:35,959 Birds have feathers and wings. 19 00:01:36,439 --> 00:01:39,340 Most of them use wings to fly. 20 00:01:40,400 --> 00:01:44,120 Feathers keep birds warm and attract other birds. 21 00:01:44,640 --> 00:01:49,640 Okay, we are going to see a little bit more about this. 22 00:01:49,640 --> 00:01:52,640 Let me make it bigger. 23 00:01:52,640 --> 00:01:54,640 Here we are. 24 00:01:54,640 --> 00:02:02,640 Okay, so it said there are thousands of types of birds, and birds come in all shapes and sizes. 25 00:02:02,640 --> 00:02:10,639 We are going to study again the same, the reproduction, the nutrition, the respiration, and the physical characteristics of the birds. 26 00:02:10,639 --> 00:02:18,520 Let's start with the reproduction. How do they reproduce? Birds are oviparous. So we 27 00:02:18,520 --> 00:02:25,599 said that mammals are viviparous and birds are oviparous. This means they lay 28 00:02:25,599 --> 00:02:32,520 eggs. They incubate the eggs by sitting on them to keep them warm while the baby 29 00:02:32,520 --> 00:02:39,520 grows inside. Los pájaros son oviparos. Esto quiere decir que ponen huevos y esos huevos son 30 00:02:39,520 --> 00:02:50,860 incubados por los pájaros hasta que los bebés crecen desde dentro y rompen el 31 00:02:50,860 --> 00:02:56,860 cascarón y ya están preparados. We are going to see the nutrition. What do they 32 00:02:56,860 --> 00:03:05,500 eat? Birds can be carnivores, herbivores or omnivores, the three types. Birds have 33 00:03:05,500 --> 00:03:13,560 beaks. Do you remember what is beak? Pico. Tienen pico. They have different types of 34 00:03:13,560 --> 00:03:19,960 beaks depending on the food they eat. As we said with the mammals about the teeth, 35 00:03:19,960 --> 00:03:26,740 the birds have different types of beaks depending on the food they eat. Because 36 00:03:26,740 --> 00:03:34,360 if they have to eat meat, they are carnivores and they eat meat, they eat 37 00:03:34,360 --> 00:03:48,039 Other animals, their beak, they have to get ready to break the food, break the meat, break the body of those animals. 38 00:03:48,939 --> 00:04:01,759 Depending on how their diet is, their beaks are prepared to take that type of food, be it carnivorous, herbivorous or omnivorous. 39 00:04:01,759 --> 00:04:09,479 adult birds find food for the babies until the babies can find their own food 40 00:04:09,479 --> 00:04:17,720 they do not drink milk like the mammals but the adult birds they find food for 41 00:04:17,720 --> 00:04:26,529 their babies let's see the respiration birds breathe with their lungs the same 42 00:04:26,529 --> 00:04:35,269 as mammals. And physical characteristics. Birds have feathers and wings. Feathers. 43 00:04:35,269 --> 00:04:44,910 What does it mean feathers? Blumas. And wings? Alas. Most of them use wings to fly. 44 00:04:44,910 --> 00:04:55,300 Feathers keep birds warm and attract other birds. We have here three types of 45 00:04:55,300 --> 00:05:02,800 birds and we are going to see what are the main characteristics. Eagles eat small 46 00:05:02,800 --> 00:05:09,939 animals. They are carnivores, okay? And they have hooked beaks for tearing meat 47 00:05:09,939 --> 00:05:17,800 apart. That is what I was explaining you before. Su pico es 48 00:05:17,800 --> 00:05:31,319 afilado para poder romper los trozos de carne para alimentarse. Penguins are sea birds. They have long 49 00:05:31,319 --> 00:05:39,959 sharp beaks which help them catch fish. Los pingüinos tienen unos picos alargados y afilados 50 00:05:39,959 --> 00:05:44,500 para poder cazar a los peces. 51 00:05:46,579 --> 00:05:50,540 Hammingbirds have long, thin beaks 52 00:05:50,540 --> 00:05:54,819 which help them eat nectar from inside flowers. 53 00:05:55,879 --> 00:06:00,500 Tienen un pico alargado y fino 54 00:06:00,500 --> 00:06:04,660 para poder tomar el néctar de las flores. 55 00:06:05,839 --> 00:06:10,160 So these are the main characteristics of the birds. 56 00:06:11,399 --> 00:06:16,279 I want you to have a look of the exercise number four. 57 00:06:16,899 --> 00:06:23,420 And it said, all birds have wings, but not all birds can fly. 58 00:06:24,040 --> 00:06:25,279 Give two examples. 59 00:06:25,439 --> 00:06:36,060 I want you to investigate animals, well, in this case, birds, that they have wings, but they can't fly. 60 00:06:36,939 --> 00:06:40,240 Pájaros que tienen alas, claro, pero no pueden volar. 61 00:06:40,240 --> 00:06:48,379 ¿Vale? Lo investigáis. And when you finish with that, we are going to do the activity book, 62 00:06:48,480 --> 00:07:01,839 okay? And we are going to go to page 14 from the activity book, page 14, and we are going to do 63 00:07:01,839 --> 00:07:07,720 exercise number one and exercise number two. I'm going to explain what do you have to do. 64 00:07:08,660 --> 00:07:15,939 Look, exercise number one is that complete the sentences about mammals, okay? 65 00:07:16,500 --> 00:07:22,819 All the information is in the pupil's book, so what you have to do is read very carefully 66 00:07:22,819 --> 00:07:29,300 what we have seen about the reproduction, the nutrition, the respiration, and the physical 67 00:07:29,300 --> 00:07:37,379 characteristics to complete these sentences, because these words, they appear on the pupil's 68 00:07:37,379 --> 00:07:50,399 Okay? So, mammals have a backbone. They are vertebrates. Most mammals are... They give birth to live babies. So, this is reproduction. 69 00:07:51,639 --> 00:07:57,459 Baby mammals drink their mothers. How do they feed when they are babies? 70 00:07:57,459 --> 00:08:08,459 mammals can be carnivores or mm-hmm this is about the nutrition what do they eat most mammals have 71 00:08:08,459 --> 00:08:19,600 mm-hmm or hair physical characteristics most mamas have four mm-hmm but dolphin have flippers and 72 00:08:19,600 --> 00:08:28,220 bat have wings all mammals breathe with their mm-hmm okay so this is exercise 73 00:08:28,220 --> 00:08:35,100 number one and then exercise number two the exercise number two it's about the 74 00:08:35,100 --> 00:08:46,039 birds okay birds and this time you have to write T or F T for true or F for 75 00:08:46,039 --> 00:08:53,840 false and correct the sentences that are false and write the correct word let's 76 00:08:53,840 --> 00:09:01,259 see the example birds are invertebrates is it correct is it true or false it's 77 00:09:01,259 --> 00:09:07,259 false and what is the word that is not correct invertebrates and then we 78 00:09:07,259 --> 00:09:11,700 correct the word vertebrates you have to do the same with the rest of the 79 00:09:11,700 --> 00:09:22,980 sentences, okay? Birds, look, it says birds are oviparous. If it's true or false, birds are covered 80 00:09:22,980 --> 00:09:36,379 with fur. True or false? Birds have two wings and two legs. True or false? Birds breathe with their 81 00:09:36,379 --> 00:09:46,639 gills. True or false? Eagles have hooked beaks for eating seeds. Seeds. Semillas. Do the 82 00:09:46,639 --> 00:09:57,139 eagles eat seeds? Penguins have long, sharp beaks for catching fish. Hummingbirds have 83 00:09:57,139 --> 00:10:02,220 Short, corto, thing, bigs, for eating nectar. 84 00:10:03,620 --> 00:10:08,559 Feathers keep birds warm and scare older birds. 85 00:10:08,840 --> 00:10:12,379 Scare, asustan a otros pájaros, the feathers. 86 00:10:13,179 --> 00:10:16,279 Okay, so you have to read very carefully. 87 00:10:16,899 --> 00:10:22,799 And if you have any doubt, what you have to do is read the pupille's book. 88 00:10:22,799 --> 00:10:29,120 OK, the reproduction, the nutrition, the respiration and the physical characteristics of the birds. 89 00:10:29,980 --> 00:10:36,399 OK, so we will correct these exercises on Wednesday or Thursday. 90 00:10:36,799 --> 00:10:40,659 OK, and we will solve all the doubts that you have. 91 00:10:41,240 --> 00:10:42,419 Bye bye.
