Killdeers are such nifty little birds. Heh, they are quite odd looking with their spindly little legs, and their call is quite comical as well.
We had quite the lot in the field behind our apartment, before they were driven over by the disgusting developers. It was the height of nesting season, and they nest on the ground. A whole bunch just scattered and we didn't see much of them for the rest of the year. You can read about the whole thing here.
But, thanks either to the Genii Loci or the economy (or both!) the property is not to be developed for some time, and the Killdeers are back.
You can find some Killdeer calls to listen to here and here.
