Most recently I was in Las Vegas for the Shot Show and came upon a Couch's Kingbird. It had recently arrived there and was the first recorded sighting ever in the state. This is a bird from south Texas and the eastern side of central america. Beautiful specie and fortunate sighting for me.
Also, I got to spend some time in the dunes just Northeast of Vegas. The late light was sculpting everything in sight, a photographers dream.
Dunes at Dusk
There is a lot to do there outside of casinos and indoor entertainment.
