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 →

GBIF citizen-science records
It is estimated from how often the Little Black Cormorant is recorded against all the birds logged in Denpasar (391 verified sightings), calibrated against known sighting rates.
