Or at least I think this is. It was very snow-covered and rather dilapidated, but the size, shape and height were all right and this is where a pair of redstarts hung out in the summer of 2011. Amazing little construction these nests. Really, when you think about it, using only their beaks, birds weave these intricate little cup-shaped nests that can hold 4 or 5 youngsters plus an adult. Amazing. In the truest sense of that word.
