As a result of twice receiving comments on photos I've posted of Fox Sparrows over the past year, I am now well conditioned to regularly look more closely at this species than I used to. I just wish I could say the same thing about Gyrfalcon :-)  Nevertheless - we had a Fox Sparrow show up this afternoon that clearly contrasts to the one we regularly enjoy watching in our backyard. 

Below is a set of side-by-side images of the Fox Sparrow we've come to expect to see everyday. I identify it as member of the Sooty major subspecies group.

The next two images are of the (new) sparrow we noticed today foraging along side the bird pictured above which I think might be a Red Fox Sparrow. I say this primarily because of its streaked back and to a lesser degree its more reddish looking plumage.

All four photos were taken at approximately 12:30 pm today - thank you in advance for your comments.
