It's a female American Horned Lark, one of the many races of Shorelark around the world. It maybe split into a separate species sometime, but currently can only be ticked as a Shorelark. The light was very harsh and difficult and I had limited processing facilities available at the time.
Some video of the American Horned Lark. The second half of the video is very interesting - at first I thought it was just having a dust bath, but the more I look at it the more it seems to be creating a nest scrape.
