What if you could just drop your kids off at someone else’s place and let them have the responsibility? Well, there are some animals that do just that. They’re called brood parasites, and they lay their eggs in other animals’ nests and let them do all of the hard work.

What's this coo-coo nonsense? Where the name came from, in Europe, the call is very distinctive, and very definitely (to my ears, anyway) kuk - koo (rhymes with buck, boo). I've heard someone say "There's that cuckoo again" because they all sound the same. I suppose cuckoos in the US don't have the same call, and so people never new that the name matches the call closely.

Hey SciShow, I've had a question for a while now, and I hope you can answer it. Whats the difference between cat food and cat treats? Why do cats enjoy the treats note than the normal food? I always lay out the two, and my cat always runs to the treat first. Please answer!

@ZaneSilverz 8 жыл бұрын

@giuseppedepascalis7067 8 жыл бұрын

Maybe I can answer... what cats actually crave in dry food is the animal fat in which it is soaked, not the food itself. Usually normal cat food has a limited quantitiy of these fats, that give a limited aroma, moreover the food is packed in big boxes where air can dissolve the scent over time. Treats (assuming you're talking about those that are actually made from dry food and not dry meat sticks) are made to attract cats, so the fats in which they are soaked are more appetizing to them and there's probably more. Treats are also usually packed in smaller boxes so the scent is kept for longer. There is also speculation that some chemical additive may be used to attract cats more and make them ''addicted'' to a particular brand of cat food, and while there's plenty of ancdotal evidence of this, no serious scientific study has been conducted that I know of, so I'll leave it at that.

@xlReGaRdLeSslx 8 жыл бұрын

Because its a treat, it doesn't have as much nutrients in it but taste good. Its like a cookie with vitamins in it. If you gave a plate of cookies and a plate of chicken to a kid, its going to eat the cookies.

I've seen cowbirds forcibly run native woodpeckers out of their nests and then lay their own eggs there. And of course, they lay their own eggs into other. species nests as well. When I saw one cowbird doing the woodpecker nest thing, I shot it with a pellet rifle. Too many woodpeckers seem to be dwindling in population where I live.

@suicune690 8 жыл бұрын

Brown-headed cowbirds actually have a good evolutionary reason for being parasites. They originally followed bison herds in the Midwest, eating insects they kicked up, and couldn't afford to get left behind sitting on eggs. The bison herds are gone now, so their brood parasitism is no longer necessary, but they can't regain the lost instincts.

The first ever cuckoo went out saying to its chicks,"I'm going to get some groceries". According to its weather-sensing abilities, a thunderstorm was gonna hit the area the next day and there was gonna be a shortage of food. But unfortunately it got mobbed on the way back. After an honest day's work, the cuckoo did what any good parent might do to bring food to the table. It had no choice but to chase down the thief-bird cuz it was gonna be night soon. The thief-bird however led it to trees it didn't know about & then into a dark cave. Little did it know that the cave was filled with the thief's pals. That evening, it got killed trying to get food for its family. The kids back at nest never learned the truth but the bird family at the neighboring nest were nice people and they adopted them little chicks. They however grew up angry and decided to abandon their kids and let other families raise them, thinking that's what's supposed to be done. And that's how the cycle began & evolved the cuckoos to be like that.

I knew about cuckoos doing this, I had no idea that other animals did it too. Thank you SciShow. There are three type of symbiotic relationship, you showed us cases of parasitism, i.e. that are detrimental to the host. Are there animal that get other species to raise their youngs without adverse effect or even with good effects? For example humans will raise puppies with the result being good for the human and the dog (most of the time). The puppies' mother does not initiate the deal so that example is a bit flawed.

"Mutualistic brood symbiosis"? Though I don't know if there is a case specifically in raising the young of another species. Raising young is a very resource-intense behavior, so it's only common that all attempt to share some of the child-caring resource from other species is somewhat harmful to the host, at least in the nature.
