Race Field Week 01 - impaled bird head

Ew. Gross, right? Imagine my surprise when I shooed away my dog Ansel to see what he was licking.

It's not everyday you see a bird's head impaled like this. In fact, I've only seen it once before and then it was a grasshopper, not a bird, that had met this gruesome fate. Like this bird, only the grasshopper's poor head remained.

I don't know for a fact this is what happened, but shrikes impale their prey similar to this. And until I did some research, I didn't know they ate/impaled other birds, so it's quite possible. I'm counting it still as somewhat of a mystery, though, because I've never seen a shrike. They look similar to a mockingbird, so perhaps I've overlooked them. I'll have to keep an eye out in the upcoming year, especially with this bit of evidence in mind.

If this is the handiwork of a shrike, I have some questions. Do shrikes typically leave the head to be eaten last, or not at all? And why would a shrike use a four-winged salt bush instead of a mesquite, lotebush, or a javelina bush, all plentiful, all having sharp thorns?

It does make for a sad photo. But, in that way of thinking, no sadder than a picture of a bucket of fried chicken.

Outside Links:
  • Here is an interesting video on Youtube of a shrike capturing a mouse and impaling it, from Israel.
  • According to WhatBird.com, loggerhead shrikes can be found here year round. Both WhatBird and AllAboutBirds.org include audio also. I need to listen a few more times to commit its calls to memory.
  • This article by Ro Wauer on The Nature Writers of Texas blog (now defunct?) is where I learned that shrikes count birds, including larger birds like mockingbirds and jays, as possible prey.

Sing, baby, Sing

Cactus wren in budding fruitless mulberry
Campylorhynchus brunneicapillus, Morus alba Striblingii


Sitting at my computer this morning, my attention was diverted to somewhere outside by the undeniable call of a cactus wren. I grabbed my camera and in my stealthiest mode went searching. Turns out little did I need to be so secretive; this guy was high in the big mulberry out front and was serious about his need for a mate. His head would contort while he sounded his chucking call, then he'd look to his right, to his left, "any takers?" A few more looks around, and then again he'd sing out. I'm hopeful for him. Surely if he can attract the attention of a hard-working computer programmer, he can attract the attention of a like-minded female of his own species.
