Scientific name Phalacrocorax carbo Common name Great Cormorant
Population name novaehollandiae, (carboides), Australia
Breeding range Australia Non-breeding range
Red List Category Least Concern
Ramsar regions Oceania
Notes carboides and steadi sometimes lumped under the name novaehollandiae (del Hoyo et al. (1996)). Taxonomic status of small population in New Guinea remains unresolved (Marchant & Higgins (1990)). Race novaehollandiae may be a separate species; alternatively, replaced by further races carboides (Australia) and steadi (New Zealand area).

Notes

  • S6365 - Overall numbers likely to exceed 25,000 and at end-of-drought (2008) were below 100,000, thus range class 25,000-100,000 is best fit; numbers are much lower than for Little Black Cormorant.
  • T5281 - Trend: possibly fluctuating but requires confirmation.
