Greater Roadrunner - aka Sneaky

There's a Greater Roadrunner that I've befriended. I call him Sneaky, and if you've ever watched these birds, you'll understand the moniker. He's got quite the repertoire of vocalizations, and I've spent enough time with him to get a sense of what he's communicating. His "bark" and his "mew," captured in videos down below, are two that I had never heard before.
