The distribution shown in the map is described in the text before and after the maps.
- Other images:
- Sonagrams. As the call shown in the sonagram is described in the text, the Alt text of the image has been set to ‘Sonagram’.
- Tables. As tables will be changed from images to text, as time permits, only simple Alt text has been added to the images as an interim measure.

- Not applied
- subspecies changes noted but not applied unless species split or lumped – AviList subspecies are not confirmed yet
- English name for Australian species as per WLAB 4.3 not AviList unless WLAB 4.3 does not cover the situation. WLAB 4.3 English names for subspecies used if elevated to species.

- extinct (Norfolk Island Ground-Dove, White Gallinule)

NOTE the other conservation statuses (ABAP, EPBC, NZTCS) have not been updated.
- Accessibility changes.
- Links underlined and external links flagged with
.
- Headings improved in about a third of entries. In some cases, this has required the addition of headings not in the HANZAB books.
- To extend the navigation options, a Page Contents tab, showing all the headings in order of appearance, has been added to the right centre of pages with more than four headings.
- note that on mobiles in portrait mode this tab might be off the screen to the right if the entry contains a wide table – either scroll to the right to see the tab or use landscape mode.

Release 1.2 (10 June 2025)
- Atherton Scrubwren revised.
- Accessibility changes.
- To support screen readers, Alt text added to:
- Maps of distribution: ‘Map of distribution’ for map of HANZAB region; ‘Map of world-wide distribution’ for map of world-wide distribution. If the map does not show all of the distribution, then the Alt text will be ‘Map of part of distribution’ for map of only part of the the distribution in the HANZAB region (usually just Australia and/or New Zealand) and ‘Map of part of world-wide distribution’ for a map of only part of the world-wide distribution. The distribution shown in the map is described in the text before and after the maps.
- Other images:
- Sonagrams. As the call shown in the sonagram is described in the text, the Alt text of the image has been set to ‘Sonagram’.
- Tables. As tables will be changed from images to text, as time permits, only simple Alt text has been added to the images as an interim measure. For example, ‘Table of food items’, ‘Table of weights’, ‘Table of population at breeding localities’. In some cases, tables with a caption have had the caption updated to described the contents.
- Banding recovery maps. Alt text ‘Map of banding recoveries’.
- Figures with only a limited caption (eg. Fig. 1) will either have the caption changed to be more descriptive or Alt text added to describe the image.
- Breeding season chart. ‘Chart of breeding season by month’.
- Some limited work has been done to the heading levels to improve accessibility (more work required; for example see Albert’s Lyrebird).
- To support screen readers, Alt text added to:
- Species which have been revised now flagged above the title with release date and release number in brackets. Also a list of the revised species has been added. The date of the last change and release number has also been appended to Content Updates if there are dated updates for the page.
- FAQs added and included in site menu.

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.
