And this allowed the scarlet monkeyflowers to hunker down in the drought.

Slow and steady survived.

And Daniel hopes this work will continue for decades, just like the long-term studies on Charles Darwin's famous finches in the Galapagos.

I did it this morning.

I highly recommend it.

No, dust-bathing ostriches do it, some species of songbirds, turkeys, and chickens.

Patricia Yang, an assistant professor at National Tsinghua University in Taiwan, says a bath for a chicken involves dirt and sand.

Ouch.

Tiny little bugs like feather mites, which can burrow into a bird's plumage and cause itching, scabbing, anemia, and all sorts of other bad things.

And then they vibrated those feathers in the sand at a rate of four to five times per second, the same frequency chickens usually reach shaking their wings during dust baths.

And almost all of the mites fell off.

Oh, wait, what's a bull shark again?

Bull sharks, they are found worldwide in warm, shallow waters, and they're really big.

Like females can grow about three meters or 11 feet.

And what's cool about this paper is they yeah, they're really social and they like hanging out with each other.

Well, what the paper is saying is basically individual sharks seem to have a distinct preference for some sharks over others.

Yeah, Natasha Morosi is a shark scientist, and she and her team looked at 184 bull sharks over six years in the Shark Reef Marine Reserve in Fiji.

They observed sharks by tagging them and through video recordings of dives.

Yeah, and the team found that a shark's age made a difference in who they associated with.

Middle-aged bull sharks tended to be at the center of social networks with more connections than younger or older sharks.
