I thought the pic I had from helping with a research project in Chiricahua NM was me holding the blactail by its tail, but its me with it in my hook. I had it by its tail, but others were freaking out, so I played nice. Other blacktail pics are from the Santa Ritas and Huachucas.

They all got defensive and rattled like crazy once I started messing with them, but they were never aggressive or eager to strike. In fact, all of these barely rattled at all when we walked past them. Like barely two tail twitches.
