Great Woodswallow

The great woodswallow (Artamus maximus), also known as the greater woodswallow, giant woodswallow or New Guinea woodswallow is a species of bird in the family Artamidae. As its name implies, it is the largest member of the genus Artamus, averaging 20 cm in length and 61 g in mass. In appearance the great woodswallow is very similar to the more widespread white-breasted woodswallow but can be distinguished by its darker black upper side plumage and by the presence of a semi-oval black patch below the throat.
