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 20% of wildlife watchers report a Little Black Cormorant sighting in Daintree National Park on a given day, based on 305 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 55th most-seen of the 208 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Little Black Cormorant in Daintree National Park on a given day, against under 5% in February–March and May, the lowest months. That is one of Daintree National Park's wettest months, with about 300 mm of rain against 50 mm in September.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Little Black Cormorant sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 23
Of the 23 parks where we can rate Little Black Cormorant sightings, Daintree National Park ranks 5th at about 20%. The best odds are in Royal National Park (Australia, about 30%), Noosa National Park (Australia, about 20%) and Wilsons Promontory National Park (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Little Black Cormorant is recorded against all the birds logged in Daintree National Park (305 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.
