This first picture captures a male Cardinal (red circle) and a Blue-jay (blue circle). I'm not sure whether or not the Blue-jay here is male or female--I'm told they can only be distinguished by their behavior. These two were on the ground picking up some of the scraps that had fallen from the feeders. We've also seen female cardinals but I don't have a picture of those (they are lighter red with bright orange beaks).
The picture below is of one of the more rare birds to come by our home (only a couple of times have we seen this variety). It's called a Rose-breasted Grosbeak. The kids liked this one and thought it looked "chunky."
This next bird looks (to me) like something you might see in the tropics with it's bright yellow feathers. It's called an American Goldfinch. It looks very similar to the Yellow Warbler but the black above the eyes give the Goldfinch away. This variety is pretty common in our area and we see these almost daily at our feeders.
Below are two more American Goldfinches. The bright yellow one on the right is the male, and the one on the lower bar with light brown tones is the female. I'm told that the males turn bright yellow in Spring and Summer but are on the paler/duller side in Fall and Winter.
This last picture is of two Chipping Sparrows. These are also very common at our feeders.
We've seen other birds too like the House Finch and the American Robin but I don't have pictures of those. We will be posting more pictures of birds soon!
