It's a bird! It's a cloud! It's a bird cloud
Apologies to Alfred Hitchcock and his creepy movie about evil birds, but sometimes truth can be stranger than fiction. This bizarre swarm of starlings isn't evil, but it's pretty astonishing. A really, really big flock of 300,000 birds created a wavelike cloud over Denmark. According to ornithologists, these feathered friends really do prefer to roost together, and the massive formations are a sort of pre-roost ritual that take on these odd shapes. Sort of like a Rorschach test in the air. Or a flying lava lamp. In short, mesmerizing

Birds? just go in the water right?

WRONG

It is one of the rarest giants of the ocean, and it has been caught on film for the first time.
An underwater camera crew filming for the BBC has recorded a smalleye stingray swimming off the coast of Mozambique.
The smalleye stingray is the largest of all 70 species of stingray, attaining widths of more than 2m.
 
How do they know there are 300,000 birds? Even if it's just an estimate, why 300,000? Why not 500,000?....100,000?...1 million?

Is there some sort of process in determining the # of birds in that video?
 
Have seen bird swarms of that ilk here in California (rare though, and it's been a while). It looks like baitfish defense, but there's no predator.

A computer model with estimated density! Duh!

I have no idea. Maybe it's just a guesstimate.
 
It's either estimate or guess, choose one or gtfo.
 
I'm glad I wasn't standing under that cloud. The amount of bird shit D:
 
I love seeing this irl because I can put my hands up and act like I'm controlling them. It's really cool.
 
Oh, man, that's amazing. From that distance, they move like one giant jellyfish-like entity. Like something you would see in a movie. Loose sand coming together to form a human face, for example. I'd love to see a better video of that.
 
I'm always amazed how large numbers of birds can move in a uniform pattern. How do they communicate with eachother?
 
we had bird swarms like this 500 years ago but it doesn't happen all that often anymore :(

I'm pretty sure I heard that none of this is exactly planned or anything.

Let's say you're 1 of the birds in that flock, and the bird beside you veers to the right, then you start to do that, then the bird next to you starts to do it and so on.


Pretty much everyone follows everyone else and it looks like they are communicating and moving together.
