I spent some time yesterday watching birds at the feeders, and had the opportunity for close observation of the birds. I wanted to share some of my shots of the Goldfinches today. Looking at the amount of black in their scalp feathers makes me wonder if like the black bib of House Sparrows, feathers during winter have lighter tips that wear away in time for breeding. I wonder if the feathers on the face and scalp are brighter gold under the dark colors. The only problem with that theory is that darker colors wear away slower and are tougher than light. It certainly could be lighter beige covering gold though for upcoming breeding. I need to read on this.
