Yesterday, a female house sparrow and a male house finch were having a conversation while perched on a railing that surrounds my rooftop garden (in NYC), as evidenced in the pictures atop this blog entry, where you can see them sharing the railing with my kiwi vines.
Normally the coloration of male house finches is red, and, knowing this, caused the little sparrow to be very concerned as to what caused this particular finch to have a white-colored face and a white head. The sparrow listened very carefully and with great empathy as the house finch confided in the sparrow saying that he had a case of leucism.
