I didn't know we had Shrikes here until I compared my image with those on bird websites. Here's a description of the bird:
A small gray, black, and white bird of open areas, the Loggerhead Shrike hardly appears to be a predator. But it uses its hooked beak to kill insects, lizards, mice, and birds, and then impales them on thorns to hold them while it rips them apart.You can't see it in these pictures, but its upper bill (if it's a shrike) has a wicked hook on the end, like an eagle's, but more like a precision needle.
Okay, then.... Nice birdy. Good birdy.
Here's a picture of one of the murderous little bastards with a horned toad. And he's perching ON BARBED WIRE!
