Amazonian moths that drink the tears of sleeping birds

Look at the photo with the bird sleeping: one moth drinking his tears and three mosquitoes trying to suck his blood. Nature is metal.

It's pretty brave of moths to do this since they are naturally preyed upon by birds. Maybe birds don't mind this activity. Perhaps there's some benefit to the birds too?

I didn't see a paywall, but there was a video that autoplayed partway down the page.

(Interesting article though.)

Anyone have a link bypassing the paywall? Or better yet, an explanation of where to find such links?

Also can we edit the title to specify there's a paywall? I don't remember if we have a policy for that around here.

I thought Eric Cartman was the only creature that drinks tears
