Brazoria, TX, USA
We observed this Great Blue Heron with a freshly caught Bowfin (Amia calva) in spawning colors at the San Bernard National Wildlife Refuge. To kill the fish, the heron put it on the ground, reared back, and stabbed it with its bill. The second time it did this, it used enough force that its bill penetrated all the way through the fish. It put the fish on the ground again, presumably dislodging it with its foot, re-positioned it, and swallowed it down whole.
