It's challenging trying to take pictures of the birds in the winter in the mountains, but its worth it. When they are not top of the trees singing, Pine Grosbeaks come down looking for food. And when they do, that's my time to take their pictures. The females have the yellow colour and the males the red. I know they have moved in when I start hearing them in later part of the fall and that's when I start spending some time taking their pictures.
