Saturday Roundup: Bird-eating Catfish and a License to Kill Crocodiles

New research documents giant catfish beaching themselves to grab and eat pigeons (awesome video of attacks above). I don't really get why people are calling them "freshwater killer whales", they seem more like freshwater catfish. Maybe killer whales are saltwater catfish.

Wildlife research doesn't have to happen in the wild. Here's a turtle study occurring in the Bronx River, New York City.

Last week I wrote about a Nile Crocodile on the loose outside Miami, Florida. The Florida Fish and Wildlife Conservation Commission decided they didn't want to take any chances. To avoid any possibility of the Burmese Python problem repeating itself, they now have orders to shoot to kill.

Ever seen a bird nest this big?

National Geographic Photo Contest 2012. Amazing photos, such as the baitfish taking refuge near a sea turtle as sailfish circle; and lessons learned, like don't throw rocks at leopards. Part II: highlight: using fire to catch fish.

A couple weeks ago I wrote about how a shark taking part in a research project off the coast of Africa was killed by people. Now the same thing is happening to research wolves around Yellowstone National Park.

Think rhinos are big today? Compare them to their relatively recent ancestors, from the blog of a researcher who stores lots of dead things in his freezer.

Last year I wrote about some research I conducted in Costa Rica on two very similar snakes. I was curious to know how these snakes could persist in the same area without competing for resources. Looks like the situation is even more complicated in Central and South America than anyone thought, here's a recently discovered species within the same genus.
