Oh my! Researchers in Virginia have found high levels of mercury in local songbirds. The birds live near a contaminated river, but do not eat any fish or other water creatures that might be contaminated. So, how did they get mercury inside of them?

Turns out the birds ate lots of spiders. And spiders are scavengers who’ll eat pretty much anything. Mercury from the environment accumulates in them, and gets passed along to the birds.

The next question is – how do the land-dwelling spiders get water-borne mercury inside of them?
