The Baudin's black cockatoo, a large and striking bird, has primarily blackish plumage highlighted with undertones of brown. It's impressive in size, with the upperparts of its body and wings featuring scattered white or light yellow specks.

Additionally, females have more prominent and numerous specks on their head, neck, and underparts compared to males.

Key differences and behavior
Baudin's Black Cockatoo (Calyptorhynchus baudinii) primarily inhabits the forests of southwestern Australia, whereas the Yellow-Tailed Black Cockatoo (Zanda funerea) is found in southeastern Australia, including urban areas. Baudin's Cockatoos are monogamous and known for life-long partnerships, with the female preparing the nest. In contrast, Yellow-Tailed Cockatoos select nest sites in ancient trees (over 200 years old) and rely heavily on old tree hollows. Dietary habits vary; Baudin's Cockatoo feeds on seeds of eucalyptus and other native trees, adapting to seasonal changes, while Yellow-Tailed Cockatoos also consume wood-boring larvae by peeling bark. During breeding, both species display courtship behaviors like mutual preening, but Yellow-Tailed Cockatoos are notable for aerial acrobatics. Baudin's Cockatoo, being lighter at 1.2-1.7lbs, is more predisposed to visit bird feeders than the Yellow-Tailed Cockatoo, which weighs 1.3-2lbs and shows preferences for natural foraging.
