Great Spotted Woodpecker Nest

While out with the Brownies yesterday we found this Great Spotted woodpecker nest  the chicks are just about to fledge so they are sticking their heads out of the hole calling for food. You can tell the age and sex of a great spotted woodpecker by the colour on its head. Chicks just after they fledge the nest have a bright red head. Once they have done their postjuvenile moult females have an all black head and males have a black head with a red stripe at the back
