Black-faced Cormorant
Phalacrocorax fuscescens
Like other cormorant species, the black-faced cormorant is a large aquatic bird, with a long hooked bill, webbed feet, and monochromatic plumage. This is one of the largest cormorants found in south-western Australia and has pied plumage with the upper half of its body black and the undersides white. Its face is naked and black, hence the "black-faced" name, and the tail, feet, and thighs are also black. The back feathers are glossy, and its bill is dark grey with a prominent hook at the tip. It has blue-green eyes. Voice: Black-faced cormorants are usually silent when away from the breeding colony. However, when they are at their nests, the male will emit a loud honk or guttural croak, and the female will hiss when approached.

Cape Cormorant
Phalacrocorax capensis
The Cape cormorant is a blue-black bird with a glossy shine. The entire body follows the same coloration. There is little to no sexual dimorphism, with both males and females measuring 61–64 cm and weighing 1.1-1.3 kg, along with a similar plumage. The beak is dark grey-black, and a deep yellow-orange gular pouch can be observed. The eyes are turquoise with a greenish eye-ring around them. Both non-breeding and immature adults have duller plumage, with a brown throat for immature adults. Juveniles are browner than immature adults, with grey eyes and a black, white, or speckled gular pouch. Voice: Vocalization in Cape cormorants is mostly used during the breeding season. Its use is significantly reduced, or even absent, during the non-breeding period. There are five vocalization variations in adults, and three in chicks. Adult Cape cormorants have different vocalizations for flying, courtship, maintenance, feeding, and the presence of a threat.
