I was following the cardinal with the camera when he flew down to the ground. That's when I realized that Mrs. Cardinal was eating at the bird feeder. (Amazing since the sparrow family that lives nearby tends to try to chase the cardinals away.)
While I was snapping photos of Mrs. Cardinal, I realized that my iris bloomed while I was at work! So after the birds flew away from the feeder, I ran outside and took photos of the iris.
