On June 11 2025 the first version of the AviList was formally launched. You can download the list from the AviList website here: The Checklist v2025.

AviList Core Team. 2025. AviList: The Global Avian Checklist, v2025. https://doi.org/10.2173/avilist.v2025

The list will be updated once a year.

The IOC bird list is hosted on a dedicated World Bird Names website. The list has most recently been updated twice a year, usually in January and July. The current version of the IOC bird list is v15.1, released February 28 2025.

My previous blog post dated July 19 2025 provided a summary of how AviList v2025 differs from IOC bird list v15.1. In that blog post only a detailed analysis at Order/Family level had been completed, although some indications of how species were being treated were also provided.

This blog post provides some lower level detail about the Non-Passerine species in AviList v2025 and highlights the differences from IOC bird list v15.1.

Here is a summary of the major amendments:

Revision and resequencing of families

32 Non-Passerine families have a new or modified English name. The species in 40 families have been resequenced. 33 other families have been partially resequenced. For other revisions and an overview of how the sequencing of Non-Passerine Orders has changed, see my previous blog post of July 19 2025. Within some Non-Passerine Orders, there has also been a resequencing of families.

In AviList v2025 there are 4308 ‘known to be extant’ Non-Passerine species (net -68 vs. IOC v15.1) ascribed to 107 families.

The AviList will be used as the basis for 2026 editions of ATWB Companion Guides. Work has begun on the implementation of the extensive changes involved. Some 2026 editions will be released in late 2025, while others may be delayed to sometime during 2026.

*********************************************************************************

Some details …

Each of the ATWB 2026 Companion Guides has a number of important features, including:

– A complete taxonomic listing of bird species

– An indication of where each bird family and species can be found in its native state

– Spotlighted species that have a restricted regional or worldwide range

However, perhaps the key feature of all eBooks in the Companion Guide series is the way you can quickly and simply access relevant, up to date online information about every featured bird species. If your reading device is connected to the internet, a single click will take you to a search results page for a species, from where you can continue to search for additional information to whatever level of detail you desire.

In future, the ‘All the World’s Birds’ series of Companion Guides will derive its taxonomy, English names and scientific names from The Global Avian Checklist (AviList), an open access resource maintained by the AviList Core Team. The AviList is hosted on The Global Avian Checklist website, which provides access to the list in two different formats.

The version of the AviList that will be used in the ‘All the World’s Birds 2026’ series of Companion Guides is v2025, formally launched on June 11 2025. Alongside the Checklist, the AviList Core Team has provided a register of corrections, v2025 errata, which can be found here. The corrections that are available at the time of publication will be incorporated into the ATWB 2026 series of Companion Guides.

KEEP IN TOUCH

Sign up to this blog to be informed about releases of new titles in the All the World’s Birds Companion Guide series, and of developments in the AviList.

The project to develop The Global Avian Checklist (AviList) began in 2016. At the time, three major global bird lists were being updated regularly, including the IOC World Bird List managed by the International Ornithological Congress (IOC). The aim of the AviList project was to harmonise bird taxonomy, scientific names, and English names to create a single reference checklist.

More information about the project can be found here: The Global Avian Checklist.

On June 11 2025 the first version of the AviList was formally launched. You can download the list from the AviList website here: The Checklist v2025.

AviList Core Team. 2025. AviList: The Global Avian Checklist, v2025. https://doi.org/10.2173/avilist.v2025

The list will be updated once a year.

The IOC bird list is hosted on a dedicated World Bird Names website. The list has most recently been updated twice a year, usually in January and July. The current version of the IOC bird list is v15.1, released February 28 2025.

This blog post provides a summary of how AviList v2025 differs from IOC bird list v15.1. At present, only a detailed analysis at Order/Family level has been completed, although some indications of how species are being treated is also provided.

 

New Orders

Family: Cathartidae – New World Vultures has been moved from Order ACCIPITRIFORMES to new order CATHARTIFORMES.

Family: Galbulidae – Jacamars and Family: Bucconidae – Puffbirds have been moved from Order PICIFORMES to new order GALBULIFORMES.

 

Revision of families

There are 255 families of extant species in the IOC bird list v15.1.

In the AviList, this number has been reduced to 251 through the following changes:

Family: Bucorvidae – Ground Hornbills has been embedded within Family: Bucerotidae – Hornbills

Family: Scotocercidae – Streaked Scrub Warbler has been embedded within Family: Cettiidae – Bush Warblers and Allies

Family: Alcippeidae – Alcippe Fulvettas has been embedded within Family: Leiothrichidae – Laughingthrushes and Allies

Family: Icteriidae – Yellow-breasted Chat has been embedded within Family: Icteridae – New World Blackbirds, Troupials, and Allies

Of the 251 families, more than a third have an English name that is different from the English name in the IOC bird list v15.1. Some of these changes simply replace ‘&’ by ‘and’, or insert ‘and’ instead of a comma.

One family has a modified scientific name. This is Family: Eulacestomatidae – Ploughbill.

 

Resequencing of Non-Passerine Orders

There are 45 Non-Passerine Orders in the AviList.

Compared to the IOC bird list v15.1 (43 Non-Passerine Orders), the most significant changes in the sequencing of Orders are as follows:

Order PHOENICOPTERIFORMES (Flamingos) is moved from position 22 to position 8.

Order PODICIPEDIFORMES (Grebes) is moved from position 21 to position 9.

These moves place the two Orders at the beginning of the subclass NEOAVES (TYPICAL BIRDS).

The following Orders have been moved from the beginning of NEOAVES to occupy positions mid-way through the sequence of Non-Passerine Orders:

Order CAPRIMULGIFORMES (Nightjars)
Order STEATORNITHIFORMES (Oilbird)
Order NYCTIBIIFORMES (Potoos)
Order PODARGIFORMES (Frogmouths)
Order AEGOTHELIFORMES (Owlet-nightjars)
Order APODIFORMES (Treeswifts, Swifts, Hummingbirds)

The other big mover is Order OPISTHOCOMIFORMES (Hoatzin), which is relocated from position 32 to position 16.

 

Resequencing of Passerine families

The standout changes in the sequencing of Passerine families include the movement of two blocks of families to positions farther down the structure. There are 144 Passerine families in the AviList (147 in IOC bird list v15.1).

Families Cnemophilidae – Satinbirds, Melanocharitidae – Longbills and Berrypeckers, Notiomystidae – Stitchbird, and Callaeidae – New Zealand Wattlebirds have been moved from positions averaging 33 in the sequence to positions ranging from 61 to 64.

Families Dulidae – Palmchat, Bombycillidae – Waxwings, Ptiliogonatidae – Silky-flycatchers, Hylocitreidae – Hylocitrea, and Hypocoliidae – Hypocolius have been moved forward by a similar amount to immediately precede Family: Regulidae – Kinglets.

Only one family has been moved significantly in the other direction. Family: Hyliotidae – Hyliotas is relocated from position 107 to position 70 in the sequence.

Also of note is the reordering of the 13 families that make up the New World Suboscine Passerines (excluding Sapayoa). Their sequence has largely been reversed, with Family: Pipridae – Manakins appearing first and Family: Furnariidae – Ovenbirds and Woodcreepers coming last.

 

Species overview

Within some families, there has been a wholesale resequencing of species. Others have been subject to a partial resequencing.

Both the English and scientific names of species appear to align well with those in IOC bird list v15.1. However, there are some instances where species have been ascribed to a new or different genus, or have a new species epithet. An example would be 11 Fruit Doves that have been moved from genus Ptilinopus to new genera Megaloprepia and Ramphiculus.

 

The AviList will be used as the basis for 2026 editions of ATWB Companion Guides. Work has begun on the implementation of the extensive changes involved. Some 2026 editions will be released in late 2025, while others may be delayed to sometime during 2026.

On February 28 2025, the International Ornithological Congress (IOC) released the latest version of its world bird list (v15.1). This was later than usual, as vX.1 versions of the bird list are normally released during January:

Gill F, D Donsker & P Rasmussen  (Eds). 2025. IOC World Bird List (v15.1). doi :  10.14344/IOC.ML.15.1.

The IOC bird list is hosted on a dedicated World Bird Names website, which provides access to the list in various different formats. The list is updated twice a year.

The details of the changes in the v15.1 release can be found by clicking on the Updates tab on the IOC website. Here is a summary of the major amendments:

There was an unusually high number of deleted species: 36. This may be due to progress having been made towards the harmonisation of the IOC bird list with other global taxonomies. In 2018, the Working Group on Avian Checklists (WGAC) was formed to record and later reconcile the differences between the major taxonomies, with the intention of creating a single worldwide list. Work began on compiling the new list in February 2021 and is now in the process of being concluded.

Genus Accipiter within Family: Accipitridae – Kites, Hawks, Eagles has been split into five genera, which has resulted in a partial resequencing.

Genus Mirafra within Family: Alaudidae – Larks has been split into four genera, which has resulted in a partial resequencing.

Genus Salpornis of Spotted Creepers within Family: Certhiidae – Treecreepers has been moved to new Family: Salpornithidae – Spotted Creepers.

Additionally, there have been some minor re-orderings of species, including:

Genus Cyanocorax of Magpie-Jays, Jays in Family: Corvidae – Crows, Jays has been resequenced.

In the IOC bird list there are now 11113 extant species (net +81) ascribed to 253 families.

The two releases of the IOC bird list this year (v14.1 and v14.2) are summarised in detail here.

The changes include the splitting of Red Grouse from Willow Ptarmigan to restore this UK/Ireland endemic taxon to species status.

A good proportion of the additional species has arisen from the splitting of:

– Common Cicadabird into eight species across n Australasia

– House Wren into seven species across the Americas and e Caribbean islands

– Island Thrush into 16 extant and one extinct species across the Philippines, Greater Sundas, n, ec Australasia, Samoa and Fiji in wc Pacific Ocean, and Christmas Island in ne Indian Ocean

All the v14.2 changes will be reflected in the 2025 editions of the ATWB Companion Guides. These editions will be released commencing September 2024.

All the v14.1 changes will be reflected in the 2025 editions of ATWB Companion Guides. These editions will be released commencing August 2024, after publication of the next version (v14.2) of the IOC bird list.

*********************************************************************************

Some details …

Each of the ATWB 2024 Companion Guides has a number of important features, including:

– A complete taxonomic listing of bird species

– An indication of where each bird family and species can be found in its native state

– Spotlighted species that have a restricted regional or worldwide range

However, perhaps the key feature of all eBooks in the Companion Guide series is the way you can quickly and simply access relevant, up to date online information about every featured bird species. If your reading device is connected to the internet, a single click will take you to a search results page for a species, from where you can continue to search for additional information to whatever level of detail you desire.

The ‘All the World’s Birds’ series of Companion Guides derives its taxonomy, English names and scientific names from The IOC World Bird List, an open access resource maintained by the International Ornithological Congress (IOC). The IOC bird list is hosted on a dedicated World Bird Names website, which provides access to the list in various different formats.

The version of the IOC bird list used in the ‘All the World’s Birds 2024’ series of Companion Guides is Version 13.2, published July 16 2023.
