It IS a tarantula hole! It's pretty early to be seeing the holes open up. Normally, it's the monsoons (July & August) that bring them out. I can only guess that the increased rain that we've had this spring confused her into thinking it was July.
I didn't post a picture of her though, because I haven't seen her. And because last year when I posted a tarantula that was walking across my driveway, it was too freaky for people. I mean, they kind of creep me out too, but since living here, I've had to move several big females that had come into the house, and one from next door. Yeah, brave me, right? I must have been having some kind of out of body experience while doing it. My body was doing the carrying, but my mind was somewhere else, I'm sure. I have seen some really beautifully colored tarantulas though, like the one at my neighbor's house.
As far as the hummers, it is migration time again, when they go through here to their northern summer homes. The photo is pretty dark, but it was dusk and it's the best lighting I could manage.
