Yellow Variant House Finch

Yesterday afternoon I spent some time in the bird blind.  It was my first chance to photograph from the blind since adding a new log as a prop.  Boy did that thing work out!  The birds were all over it.  I had more opportunities to shoot than I could manage.

One thing that was super cool was getting to photograph this Yellow Variant House Finch.

I had never seen one of these birds before so I had to call my resident bird nerd, David Akoubian from Bear Woods Photography.  He said he thought it might be a Yellow Variant House Finch, and he was right.  After a little Googling, I found out some information about these birds.  Apparently the yellow variant is derived from diet.  I guess if their diet does not contain a certain carotenoid pigment, it causes more yellow than red coloration.  From what I read these birds are more common in Hawaii and the Southwestern US because many of the natural foods in that area lack the necessary carotenoids.  I was certainly glad to see him at the feeders.  Maybe he will hang around for a while.

Image made with my Sony A77 II and Tamron 150-600mm Lens.  Camera combo was mounted on a Sirui tripod and PH-20 Gimbal head.
