The black-browed albatross (Thalassarche melanophris), also known as the black-browed mollymawk, is a large seabird of the albatross family Diomedeidae; it is the most widespread and common member of its family. Mollymawks are albatrosses in the family Diomedeidae and order Procellariiformes, which also includes shearwaters, fulmars, storm petrels, and diving petrels. These birds share certain identifying features. They have nasal passages that attach to the upper bill called naricorns, although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as being an energy-rich food source for chicks and also for the adults during their long flights. The albatross also has a salt gland above the nasal passage which helps to remove salt from the ocean water that they imbibe. The gland excretes a high saline solution through the bird's nose.

Rare
Under 5% of wildlife watchers report a Black-browed Albatross sighting in Great Otway National Park on a given day, based on 70 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 124th most-seen of the 175 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Black-browed Albatross in Great Otway National Park on a given day, against under 5% in September to June, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-browed Albatross sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 7
Of the 7 parks where we can rate Black-browed Albatross sightings, Great Otway National Park ranks 5th at under 5%. The best odds are in Tierra del Fuego National Park (Argentina, about 10%), Península Valdés (Argentina, about 10%) and Booderee National Park (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-browed Albatross is recorded against all the birds logged in Great Otway National Park (70 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
