The little black cormorant (Phalacrocorax sulcirostris) is a member of the cormorant family of seabirds.

The species is now placed in the genus Phalacrocorax that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The genus name Phalacrocorax is the Latin word for a cormorant. The specific epithet sulcirostris combines the Latin sulcus meaning "furrow" with -rostris meaning "-billed". The species is monotypic: no subspecies are recognised.
A molecular phylogenetic study published in 2019 found that the little black cormorant was sister to the Indian cormorant. It is estimated that the two species split 2.5–3.2 million years ago during the late Pliocene. The little black cormorant is a small cormorant measuring 60–65... Wikipedia →

Possible
About 30% of wildlife watchers report a Little Black Cormorant sighting in Royal National Park on a given day, based on 768 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 178 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
September to November
In those months about 40% of wildlife watchers report a Little Black Cormorant in Royal National Park on a given day, against about 20% in February to May, the lowest months.

GBIF citizen-science records
It is estimated from how often the Little Black Cormorant is recorded against all the birds logged in Royal National Park (768 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.
