This striking little neighbor is the Cardinal. During courtship, the male feeds the female. Wikipedia states that this bird was once prized as a prized pet species but its sale as a cage bird has been banned for nearly 100 years. Cardinals are extremely territorial and can relentlessly attack their mirror images in windows.
