The Grey Goshawk (*Tachyspiza novaehollandiae*) is a medium-sized bird of prey renowned for its striking polymorphism, appearing in either a pure white or a distinctive grey plumage. Adults measure 38-55 cm in length with a wingspan of 70-110 cm, and females are notably larger than males, a common but pronounced trait in raptors. The pure white morph is entirely white with bright yellow legs and dark eyes, while the grey morph exhibits dark grey upperparts, a white finely barred underside, gr...
