Survival (how to eat without being eaten)

Your challen is so informative, it needs to be spread around even more. Just recommended it to some of my friends. Your example with the sea gulls reminded me of a strange behaviour of crows I came across once. There was a group of crows sitting in a tree. Not nesting (would've been the wrong season for it, was around in November), just about 10 or 15 crows sitting in that tree, when a bird of prey came by. It flew over the field, seemingly uninterested in both the field and the crows. Suddenly one of the crows flew up an attacked the bird of prey - alone. It was around half the raptor's size, but it got so aggressivly intrusiv, that the raptor turned around and fled. The other crows kept sitting in the tree and crowing really loud, even after the raptor was gone and their peer came back.
I observed similar behaviours on other occasions, but mostly because there was either a nest nearby or the raptor made some prey and the crows tried to steal it. But I never saw something so seemingly pointless. It was almost like the crow was undergoing some test of courage.

How does the theory of dilution of risk work out mathematically? I should think that if prey group themselves, predators will just converge in their own numbers on the grouped prey. Nothing about the explanation given here suggests there will be any fewer predators than there would be if the prey stayed dispersed. Nothing about it suggests that a given individual predator will have any less success. It seems to me that the probability of an individual of the prey species being eaten remains the same, at best, as a result of the grouping behavior. So, I don't get "dilution" theory.

I’m a newbie when it comes to gazelles but the footage of the jumping gazelles doesn’t look like Thomson’s gazelle 🤔

Thx from germany

Here is a comment to feed the algorithm.

Amazing as always doc

Hail to the almighty algorithm!

I never comment on things but the series is great and the view counts don’t make sense to me so trying to help! I think if you added a description to the video it may help with the algorithm, I’m not an expert though.

These videos are very information dense and it's wonderful.

fantastic series

This series is critically underrated! Here is a comment to feed the algorithm. Remember to like the video if you want more people to find this channel!

I got to the comments second.

Please reply below and tell me what position you managed, I'm really interested but remember, don't take the positioning too seriously, it's just for fun
