A woodpecker of Saguaros eats the brains of mourning doves. This strange behavior was filmed in a desert area near Tucson, Arizona by ornithologist Harold Greeney. Taking advantage of the absence of the parents, a pic of the Saguaros or woodpecker of the Gila hit the head of the chicks violently with its beak to extract the brain. According to the ornithologist, the bird was mainly interested in the cerebral-spinal fluid contained in the skull of the chicks, a valuable source of water in the desert. The pic is essentially insectivorous, but they can also drink nectar, eat fruit and chick eggs quite comparable to a skull eventually. At the end of the video you can see one of the parents doves back to the nest, but it's too late. One of his cubs fell from the nest and the other almost died.
