About the same size as the Common Buzzard and rather similar in plumage, and can be confused when seen flying. Its iris is a characteristic yellow and the bill has a distinctive shape, being rather longer and finer than Common Buzzard. They nest in trees in dense woodland, with a diet typically based on bees and wasps (the larvae, pupae and adults) and can be seeing carrying parts of wasps nest or honey combs in their talons. They also take reptiles and small birds. They breed in Extremadura and migrate across the Straits of Gibraltar in September.
