Gray sky early

It looks like fog, only high up.  The sun gets through at times.  At least three wrens are busy around the birdhouse.  I don't know if the third is a helper or a competitor. 

The gray burned off and now it is hot and sunny, but a bit hazy.  Lots of skinks are out, adults and blue tails.  Butterflies and bees are roaming.  The birdhouse move-in continues.  Crows chased off a hawk but ignored another big bird with a white head.

Later a single crow escorted off another raptor, a coopers or a sharp shin, I think.  We had supper outside but it was a bit buggy.  I hope the house wrens feed well.  They were still hard at work. Some wood ducks paddled downstream but I was only able to photograph the last one.
