A few weeks ago there were 21 birds, then 20 in a couple of days. There are still 20 as of a few minutes ago. We have wondered what they were eating when they chose our lawn. I think it is the frozen green lawn grass that they are digging up. At least, that’s what I see in the areas where they scratched up food. There is a coulee near our place and I guess they winter in the brush there. But, they like what this frozen lawn has to offer, even if they have to dig for it.
