Burrowing Owls

I walk my 2 dogs in the dessert, this time of year is difficult because of the rattlesnakes. Murphy's goal where rattlesnakes are concerned at to kill or be killed. So, I keep the dogs close. Last Thursday evening, these two appeared out of no where, alternatively dive bombing or luring my dogs away. I may be giving them too much credit, but I swear they actually herded Finn right to me after I caught Murphy and put him on leash. They sure did herd Finn directly at me so I could catch her, too. But, while all of this worked to get my dogs away from their den, it also gave me a very good idea of exactly where it was, so Saturday morning I got up early and went back out without the dogs (the first time I've ever done anything that evil to them). I didn't want to get any closer than this, I didn't want to make them nervous I assume they've got young-uns they are protecting.

While I'm pretty sure this is just a house finch, what's up with her eyebrows?
