Thanks,, I also added a couple of cinder blocks at the side of the driveway to further encourage people to stay off that side. So far, she doesn't seem to mind the flags at all. To her, they probably just seem like some bizarre plants that sprouted up overnight.
Killdeer prefer gravel beds for their nests. The only handy one around here happens to be our driveway, which we need to use from time to time. Fortunately this year, she built her nest at the edge (instead of in the middle, where she built it a couple of years ago). You don't normally see them this close to their eggs, because when anybody gets close, she transmogrifies into a hideously wounded flopping pathetic bird which draws the intruder's attention away from her eggs. It's quite a performance. Her nest is surrounded by colorful flags, right now, which rather defeats the purpose of camouflage, but makes it less likely anybody will run over her eggs. #birding #birdphotography
