Animal Migration: Where's that gnu gnoing?

using colons alt l. Let's not change the name. We should change the name to just try and find a pulse. That's good, Thank you, Chuck. Yes, have you ever seen him animal migrate? I see my dogs migrating to the food bowl at five o'clock every day. Yeah, I guess that is kind of migration. Yeah. Actually I see them migrate to me at like four thirty and starts staring at me like you know, you gotta Feti's right. Yeah,

we talked about that and can dogs perceived time? That's right? Um, I have seen animals migrate on the YouTube's Oh it's gorgeous. It is, I mean, it's unbelievable. It is, especially depending like the monarch butterflies. To everyone's like, that's the money migration, not to me. Have you seen the bats, the fruit bats in Zambia. That's pretty amazing. It is amazing and like horrific. If you don't like bats, I like the mammalion ones, like the elk, thousands and thousands of them

steaming across the tundra. Uh. And the the yeah, caribou, that's another one. Um. Will the beasts also called gnoos no canoes is good gnoos? Gary, Did you know that? I didn't know that the will the beast a k a. The canoo is also known for its huge migration, and that doesn't always go very well. Did you know that?

What with? Uh? What happened in a river in Kenya in two thousand and seven ten thousand, Will the Beasts drowned at this one spot in this river because one of them went in and got swept away, and the rest of whom were like, oh, we went in, Well, I guess we all just crossed and that's really sad. Yeah. One person of the population of the African will the best population, died in that river that day. Quite a mess too, I imagine. Yeah, I mean that would probably

damn up the river. I would think, I would think. So ten thousand canoes will the beasts? I mean they're about four and a half feet tall at the shoulder. They're big, um and yeah, ten thousand of them, that's a lot of biomass. It's like when a whale gets beached. Do you remember the one in Oregon in the seventies that they blew up with kin of mine? Yeah, so that's migration, Chuck, you got anything else, listener, mail it just blacked out, Josh. Migration if we should define it

for our foreign friends, exactly. It is a large scale movement of an animal species, and typically it's because of a few things like whether or mating, or food trying to find resources. Yeah, so when you said that you see your dogs migrate to their food bowl every day, that does technically count its migration because most of the reason things migrates food, and then the other ones are generally secondary. Josh, what are the three types of migration?

There is irreversive migration, eruptive migration. I just made up a word. Irreversive and not eruptive is in the volcano. But I are are compeat. That's right, um, And that doesn't follow a pattern. Uh. Usually it kind of the basically the species is making it up as it goes along. Um. The wilder beasts are known for eruptive uh migration because they follow water and wherever the water is, they're going to it and apparently drowning in. And they said to

in this article, which is crazy that they will. Their migration patterns can be based on like thunderclouds. Well, yeah, they hear thunder, go to the thunder because that's where the rain is, meaning that's where the water is. It's just so cool. How smart the stupid looking cannon is means didn't carry you to wear a turtleneck and a jacket. I think it was a dickey okay, uh josh. Another one is complete and partial migration. Um. Obviously, complete is

when the entire species migrates. Um. Partial usually happens when you have such a range in your species that some of you live where it's nice and warm you don't have to go anywhere, and some of you live where it's cold. And the barn owl is a good example of that one. Partial migration is basically just species showing off how much range. It has like some of us

don't even need to migrate exactly. There's also um altitude altitudinal migration, where you're a billy goat up in the Alps and it starts to snow and get a little cold for you, so you move a little further down the mountain. Yeah, being banged boom migration done. And the final one, actually I think I said three, this is more like five. Uh, is the saddest one of all,

and that's removal migration. And that is when wherever you're living, for one reason or another, whether it's deforestation or drain swampland swampland or climate, is just not the place to live anymore, and you just pack your bags as a species and leave, never to come back. It is the saddest migration. I think. So um, so chuck. That's the types of migration, the three slash five types three to

five yeah. Um. And what we're finding is from the outside, it looks like people who studied migration, before we studied migration, it was just like I like, the animals are moving again. Um. But people have given it a lot more um evaluation over the last decades century. Year two right, um and they're finding that there's pretty much well, like we said, food, breeding, in mating, and um climate climate, those are the reasons and they all equal survival. Yes, that's the whole point, right,

you said that um partial migration is based on range. Yeah, what animals need is food. You gotta have food to survive, and for the most part, that's why animals migrate is for food. And what's interesting too, it's it's not always a migration to like, oh, let's go find because there's tons of food over here. Sometimes they're smart enough to know we'll deplete all the food here if we don't move around some and we want to survive as a species, so we're not going to take all the food here.

We're gonna migrate over and kind of spread it around so we can all live. Right, It's pretty cool. Water also falls into that category of survival as well, like the wilderbeeste which we were talking about, right, Um. And then there's breeding and mating as reasons for migration. Whales are very very famous for migration for both actually for feeding and for breeding. Right, So they migrate to the

poles in the summertime thousands of miles. Yeah, Um, they migrate to the poles in the summertime to go feast on krill, but their calves when they're born don't have enough lover to survive in the polar climate that's adorable, so they go toward the equator the tropical climates to um mate and and reproduce. Do you ever look at animals and think they figured it all out and humans are just messing it all up? Yes, frequently, I say

that all the time to myself. The chinook salmon josh is one in relation to mating and breeding, and they are famous for heading out to see as adults after they're born in the river, and then later in life they swim back upriver and they lay their eggs at the same hospital where they were born, the same little river spot, because they're going to be eaten in the open sea, so they go back to where they're born because it worked for them. Well, that's exactly why they

do it. That's amazing because they know that the spot is because I'm alive, it's safe. I know this is a safe spot for me. Plus I haven't been by there for a while. I need to say hey to the to the old neighborhood exactly see what's going on? And check you're talking about removal migration. UM. There's a pretty there's a good example of UM. What happens as a result of removal migration UM in the whooping crane? Right, this is the best story. Do you like this one?

It's really awesome. The being crane UH in the United States went down to twenty birds in the wild for a little while. That's not a good part, by the way, that's the funny part. Here's the good part. UH. The eastern population of the species was completely wiped out and the western population was pretty much keeping the species alive. So I guess to oppose removal migration, is it Rutgers?

I believe it was Rutgers ornithologists UM really started to take a real shine to the whooping crane and and wanted to get the population back up, and so they started breeding them in captivity. The problem is the annual migration of the whooping crane is about twelve miles. They

go from the north down to Florida. UM. They learned that that's intergenerational knowledge, right, So the ones in the east, they have no idea how get from there there where they live during the summertime, down south in the winter. They don't know the route because those people who used to or those cranes that used to have that knowledge died out right. I know, it's so sad, So tell them what they're doing, Chuck, Well, this is the cool thing.

As sad as that is, and as down on humans as I am, there are humans that do amazing things like this. They basically dressed up and whooping crane costumes from the time these little chickies were born to acclimate them to to you know, the adults and uh, the sound of an ultralight aircraft from the time they were

little ones. Stick got them used to that sound. Then when the time came to my great Josh, the birds, a guy got into an ultralight aircraft dressed dressed as a whooping crane and flew from Wisconsin to Florida and lead these birds and basically said, this is the way to go, This is how you're going to survive. How awesome is that? It's pretty awesome and it worked so far. So far. They're what they're hoping is, obviously in generations to come, that they have learned this and they'll be

able to pass it down. Yeah, exactly, Yeah, that's so awesome. UM. That's pretty rare actually that we understand why or how a species UM migrates for the most part, how and when or how they how they know to migrate. It's still relatively a mystery. UM. There's different ways that that we think an animal species can say, Okay, it's time to go to Florida um. And one of the one of the big ones, is called the photo period based on the Circadian rhythm or the Circulean rhythm. Sunlight
