HANZAB book structure
HANZAB Taxonomy
For sources used to compile the taxonomy below and treatment of conflicts see notes after the taxonomy.
For an expanded version of the taxonomy see Expanded HANZAB Taxonomy or All taxa in current taxonomy.
For previous taxonomy, see Previous taxonomies.
The taxonomy above is derived from the following sources:
- AviList 2025
- orders, families and species and the taxonomic sequence
- English name for species not in WLAB 4.3
- WLAB 4.3 (Birdlife Australia)
- For English names of Australian species
- Checklist of the Birds of New Zealand, Sixth Edition, 2024 (Ornithological Society of New Zealand) referenced as NZCL 2024
- Rarity committees of Australia (BARC) and New Zealand (NZ RAC), accepted records.
- Birdlife International datazone website for the species recorded in Antarctica, French Southern territories, Heard and MacDonald islands, Bouvet Island, and South Georgia and South Sandwich Islands (Accessed 23 March 2023).
Where the treatment varies between these sources, it may be noted by comments in the text or by presenting each variation with comments. Eg. subspecies cooki of Red-fronted Parakeet Cyanoramphus novaezelandiae in WLAB 4.1 is elevated to species level (Norfolk Island Parakeet Cyanoramphus cookii) in NZCL 2022. See Taxonomic changes since HANZAB book published in Red-crowned Parakeet (the NZCL 2022 name for Red-fronted Parakeet) or HANZAB Index+ for the treatment adopted.
