Taxonomic note

Trichoglossus haematodus, T. forsteni, T. capistratus, T. weberi, T. rubritorquis, T. moluccanus and T. rosenbergii (del Hoyo and Collar 2014) were previously lumped as T. haematodus following Christidis and Boles (1994), and before then were split as T. haematodus and T. rubritorquis following Sibley and Monroe (1990, 1993).

Population
Estimate Data quality Derivation Year of estimate
Population size 10000-19999 mature individuals poor estimated 2014
Population trend decreasing - suspected -
Generation length 5.7 years - - -
Number of subpopulations 1 - - -
Percentage of mature individuals in largest subpopulation 100% - - -

Population justification: The population is thought likely to be moderately small (i.e. approaching as few as 10,000 mature individuals).

Trend justification: The population is suspected to be in decline owing to habitat loss and unsustainable levels of exploitation.
