A friend told me the location of a pair of Brown Creepers building a nest. I spent yesterday morning with them, in Frontenac State Park, south of Red Wing. Brown birds working on a brown/gray tree trunk in dim light filtered through a green canopy made good color difficult for me, but my subjects were cooperative. The pair of birds made a trip to the nesting cavity — beneath a piece of bark pulled loose by a break in the tree — about once every five to 10 minutes. They brought strands of grass and what looked like fluff from thistle plants. They were working at this Sunday as well as yesterday. They stuffed a lot of material into that hole. Here is one of the color shots, and two in black and white. I told someone last week that bird photos don’t work in b&w. Well, it depends. Frontenac, by the way, was very birdy. It’s an excellent birding location during migration.
