File:Crow eating a Chinese Mystery Snail.jpg

Summary

The American Crow (Corvus brachyrhynchos), is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America. In the interior of the continent south of the Arctic, it is simply "the crow" as not many other such birds occur there on any regular basis.

This one happens to be eating a Chinese Mystery Snail (Cipangopaludina chinensis), a very invasive species in Minnesota.

I had never seen snails that big in my life (about 3 inches long and 2 inches in diameter), but this particular lake was full of them. The entire lake looked like this, so you can see how an invasive species like this snail kills everything else off that lives there. There is nothing left in that lake but snails, they eat everything.
