Frost and flocks

The creek is only half skinned over with ice but the frost is white on every surface.  A great blue heron and a great egret, gulls and cormorants flew over it, and a mallard pair paddled down.  On the far bank, a large flock of birds gathered in the grass then startled into the trees, repeatedly.  I thought they were mixed blackbirds but the ones that came close enough to identify were robins.

Juncos poked through the frosty mulch.  The first birds on the feeder were chickadees and a titmouse.  Then a pair of finches came.  White throats and a wren snatched peanut bits.  The sun is now fully up and melting the frost. 

The female towhee and a yellow rumped warbler joined in around 10am.  The titmouse was back too, but eluded the camera.  The towhee kept flaring her feathers as though she were experiencing digestive discomfort.
