Bluebird of Haziness

I spotted a small flock of Bluebirds (Eastern Bluebird - and probably heading south a bit late) while doing my camera walk through the field across the road but they were moving quickly as I approached.  The only shot I got was this hazy blur of blue on the shed roof.  I started to delete it but then decided that it was the only evidence that they had been here in the snow - so here it is in all its' haze of glory.
