Another foggy day

The high pressure continues to build and the resultant pollution and fog fill the valley.  The sun worked hard to get through today, finally really showing up about noon. 

Lots of harriers and kestrels at the refuge, with two mature bald eagles in their normal spots on the dead trees.  A blue heron floated in but landed far down the stream so no pictures.  A marsh sparrow ( need to look this guy up to be more definitive) was eating seeds on a thistle covered in hoarfrost - very pretty.  And a rough-legged hawk would fly back and forth between power poles so I could get a picture of him/her!
