Backyard and Beyond

Starting out from Brooklyn, an amateur naturalist explores our world.

As John Burroughs said, “The place to observe nature is where you are.”

Jawbones

Rodent. Which one? Found amid an owl (and other?) pellet bonanza recently.Jaws a-plenty, in fact, but no skulls. The last time I found a good patch of pellets, there were lots of skulls. Some owls will eat the head first, then the body later. Inch scale here.And this one with the long incisor. When I first spied it, I wondered for half a second if it was a talon, which I understand have been found in pellets (Great Horned Owls will eat anything). But it’s just an incisor that slipped out of the deep pocket (yeah, not the anatomical correct word) in the lower jaw. As with us, the roots of their teeth are buried deeply in the bone. Rodents are characterized by their pairs of continuously growing incisors on the upper and lower jaws.
