A pair of Red Breasted Nuthatches were busy at the feeders today. I got good long looks at them as they pulled peanuts from the mesh feeder. It was a chance to really take in the differentiating feature between the male and female - the color of the top of their heads.
Males have a black cap which is in strong contrast to their slate-colored back. Females have a much lighter cap that at times seems to just merge into the slate color of her back.
White Breasted Nuthatches can also be differentiated in this manner.
I just wish the Red Squirrel would stop looking at me through the window!
