Black-faced Cormorant
Phalacrocorax fuscescens

This is the least common cormorant native to Australia and the one with the smallest distribution, being found only on coastlines on the southern shores of the country. They are medium-sized at 60-70 cm, placing them in the middle of the five Australian cormorant species. They are much more marine-based that the other four, favouring harbours, islands and rocky coasts. The main ID challenge is to separate them from a juvenile Little Pied Cormorant, but the Black-faced has a longer, straighter beak with a hooked tip.
