Current Totals

As of May 28, 2018, the TiF list contains 10928 species in 2406 genera, 251 families, and 46 orders.

Comparison with IOC list, version 7.1

(not updated since last year) As of May 31, 2017, the TIF list contained 10898 species. The differences between the TIF and IOC lists involve over 270 species (103 species removed, 172 species added, compared to IOC 7.1). Of the 103 species on the IOC list that I have not included, about 75% are New World species that neither of the AOU committees has accepted. I will eventually reconsider both these and the extinct species. Adding all of the extras would bring the TIF list to 11000 species, 172 more than the IOC 7.1 list (10828).

IOC English Names

Although I started with the Howard-Moore list, I am now using the IOC list as a baseline. Every species gets an IOC-style name. That doesn't mean its the only name, or that it exactly matches the IOC name. Four percent of the species have two names. This usually happens because of differences between the IOC name and the AOU name (NACC or SACC). In such cases, I usually give the IOC name second, even in cases where I think the AOU name is stupid (E.g., redstarts for the Myioborus whitestarts). A few other non-IOC names have also been retained.

Some IOC-style names don't exactly match the true IOC name due to differences in taxonomy. For example, IOC recognizes two species of Laniisoma—Brazilian Laniisoma and Andean Laniisoma. In this case, I currently follow SACC taxonomy which has only one Laniisoma. However, their English name is entirely different (Shrike-like Cotinga). Keeping in mind that the species has been known as the Elegant Mourner, I added the IOC-ish English name Elegant Laniisoma.

The IOC-style names have been fully Americanized (gray, not grey; AOU-style hyphenation). I'm also a little more aggressive than AOU in adding hyphens to break up two-part names that don't scan well. I also favor hyphens when it makes the “last name” of the bird clear. Hyphens greatly improve the results when sorting bird names by last name. I know some people fight flame wars about it, but to me, bird names that differ only in hyphenation and/or American vs. British spelling, such as Grey Pileated Finch and Gray Pileated-Finch, are essentially identical (and are the IOC name).


Stephen Nawrocki has updated his enhanced excel spreadsheet of the TIF world list to Version 2.79. Numbering now matches the csv files.

Four lists are also available in csv format. Three of the lists use the TiF species list for that area. The ABA list has been modified to match the ABA species list.

The ABA list includes only ABA species, but in TiF order. The AOU and South American lists have a slightly different species list than the AOU's corresponding lists.

Piculets: The Latin American piculets have been rearranged based on Shakya et al. (2017). Their results suggest that some adjustment of species limits will be needed, but that awaits further studies. A hybrid piculet I saw in Minas Gerais (Brazil) earlier this year suggests the issues go beyond found by Shakya et al.

Surprisingly, they found that the Olive-backed Woodpecker, Dinopium rafflesii, is sister to Gecinulus. As a result, I've placed it in the monotypic genus Chloropicoides (Malherbe 1848-49).

Other changes prompted by Shakya et al., include rearranging Piculus and Yungipicus and adjusting the position of the Red-headed Flameback, Chrysocolaptes erythrocephalus and of the Helmeted Woodpecker, Celeus galeatus. Even though Shakya et al. (2017) and Dufort et al. (2016) have differences in the overall arrangement of the woodpeckers, I continue to follow Dufort et al. (2016) which seems to use more data.
[Picidae, Piciformes, 3.08]

August 6

Rails: The former Gray-necked Wood-Rail, Aramides cajaneus now goes as Gray-cowled Wood-Rail / Gray-necked Wood-Rail, Aramides cajaneus, with the former English name used by both the AOS NACC and SACC, and the latter used by IOC.

I've also rearranged the Laterallini based on tree B in Stervander et al. (2019). As a result, Atlantisia is merged into Creciscus and the Gray-breasted Crake returns to Laterallus as Laterallus exilis. [Rallidae, Gruae I, 3.04]

August 5

Dry Forest Sabrewing: The Dry Forest Sabrewing, Campylopterus calcirupicola, is recognized as a separate species related to the Gray-breasted Sabrewing, Campylopterus largipennis. See SACC #756 and Lopes et al. (2017). Lopes et al. and SACC #755 suggest there are additional species in this complex. I saw this bird in June at Lapa Grande State Park (Minas Gerais, Brazil).
[Trochilidae, Apodiformes, 3.10]

Cupwings: Pnoepygidae is now referred to as the Cupwing family. The English last names have been changed to reflect this. [Pnoepygidae, Paroidea & Sylvioidea I, 3.11a]

August 2

Today's changes are from AOS Supplements #58 and #59. These changes are NOT included in the latest CSV files. I did not adopt the Cassia Crossbill split because I have skepticism about it, even though it seems to have the strongest case of all potential North American Red Crossbill splits.

Thayer's Gull: Thayer's Gull, Larus thayeri, has been lumped into Iceland Gull, Larus glaucoides in accordance with the AOS 58th supplement.
[Laridae, Charadriiformes, 3.05]

Automolus Foliage-gleaners: The Chiriqui Foliage-gleaner, Automolus exsertus, has been split from the Buff-throated Foliage-gleaner, Automolus ochrolaemus. See AOS Supplement #59, which is based on the analysis of their response to calls by Freeman and Montgomery (2017).
[Furnariidae, Furnariida II, 3.06]

Baird's Junco: Baird's Junco, Junco bairdi has been split from the Yellow-eyed Junco, Junco phaeonotus as per the AOS 58th Supplement. The phylogeny follows Friis et al., 2016), where Baird's Junco is not even sister to the Yellow-eyed Junco.
[Arremonidae, Core Passeroidea III, 3.05]

White-collared Seedeater: The White-collared Seedeater, Sporophila torqueola has been split into Morellet's Seedeater / White-collared Seedeater, Sporophila morelleti and and Cinnamon-rumped Seedeater, Sporophila torqueola based on the AOS 59th Supplement and Mason et al. (2018). As with the Juncos above, they are not sister taxa.
[Thraupidae, Core Passeroidea V, 3.06]

Comparison Spreadsheet: Richard Jackson has provided an updated TiF-based spreadsheet cross-referenced to the IOC list, the 16 volumes of HBW, and the two volume HBW/BirdLife Illustrated Checklist (ICBW).

CSV Files: The CSV files have now been updated to version 3.10. These updates reflect changes to my personal list that have not been posted yet.

Subspecies List These changes are reflected in two speadsheets provided by Dale Mitchell. These are a subspecies list and family-genus finder (both of which I have slightly edited).

I've made many changes in the babbler clade based on the recent paper by Cai et al. (2019). Most of the changes have been minor. Nonetheless, there have been changes to Sylviidae, Paradoxornithidae, Timaliidae, Pellorneidae, Alcippeidae, and Leiothrichidae. Zosteropidae will be affected too, but things are more complex there and with one exception will wait for a later update.

The following changes deserve mention:

  • The Abyssinian Catbird, Parophasma galinieri, becomes Sylvia galinieri. (Sylviidae)
  • Atraphornis and Melizophilus have been separated from Curruca. (Sylviidae)
  • The Reed Parrotbill, Paradoxornis heudei, becomes Calamornis heudei. (Paradoxornithidae)
  • Cholornis has been merged into Conostoma. (Paradoxornithidae)
  • Neosuthora has been merged into Suthora. (Paradoxornithidae)
  • Sinosuthora has been merged into Chleuasicus. (Paradoxornithidae)
  • The White-collared Yuhina, "Yuhina" diademata, becomes Parayuhina diademata. (Zosteropidae)
  • Trichastoma has been resplit from Pellorneum. (Pellorneidae)
  • I was previously doubtful about where the two species of Melanocichla belonged, but not nearly doubtful enough. Melanocichla has been moved to Timaliidae from Leiothrichidae. (Leiothrichidae)
  • Malcolmia, Chatarrhaea, and Malacocircus are subsumed in Argya. (Leiothrichidae)
  • Kupeornis has been merged into Phyllanthus. (Leiothrichidae)
  • Stactocichla merged into Leucodioptron. (Leiothrichidae)

Updated Jackson Spreadsheet: Richard Jackson has provided a new version of his spreadsheet comparing the TiF, IOC, HBW, and HBW/BirdLife Illustrated Checklist (ICBW) bird lists.

June 6

Birds-of-Paradise: Based on Irestedt et al. (2017), the riflebirds have been returned to genus Ptiloris and the Superb Bird-of-paradise, Lophorina superba is split into:

  • Lesser Superb Bird-of-Paradise, Lophorina minor, monotypic.
  • Vogelkop Superb Bird-of-Paradise, Lophorina superba, inc. niedda.
  • Greater Superb Bird-of-paradise, Lophorina latipennis, inc. addenda, feminina and latipennis.

Note that Irestedt et al. argue that superba does not apply to birds from the Vogelkop Mountains, but to those usually called feminina. They establish a new name inopinata for the Vogelkop birds and refer to the Vogelkop Bird-of-paradise as Lophorina niedda. They also call the Greater Bird-of-paradise Lophorina superba. Given that the type of superba has been considered to be from the Vogelkop, I didn't find their arguments convincing.

Also, I've added Raggi's Bird-of-Paradise as the primary name of Paradisaea raggiana, the point being that it is named for Francesco Raggi.
[Paradisaeidae, Corvida III, 3.04]

Scrub-Robins: Aedonopsis Sharpe 1883, replaces Tychaedon Richmond 1917 on the grounds that Aedonopsis Sharpe 1883 is not preoccupied by Aedonopsis Rey 1872, which is not available due to the fact that it is merely an incorrect spelling of Aedonops Brehm 1863. See Raty, BirdForum 2018.
[Muscicapidae, Muscicapoidea II, 3.13]

May 20

Chaetura Swifts: Continuing the Ridgely splits (Ridgely and Greenfield, 2001), I've split Tumbes Swift, Chaetura ocypetes, from Short-tailed Swift, Chaetura brachyura.
[Apodidae, Apodiformes, 3.09]

Cardinalidae: Another IOC/Ridgely and Greenfield (2001) split is Olive Tanager, Habia frenata, from Carmiol's Tanager, Habia carmioli.
[Cardinalidae, Core Passeroidea V, 3.05]

Thraupidae: Still following IOC and Ridgely and Greenfield (2001), Yellow-tufted Dacnis, Dacnis egregia (inc. aequatorialis) has been split from Black-faced Dacnis, Dacnis lineata.

Also, the Black-and-chestnut Warbling-Finch, Poospiza whitii, has been split from the Black-and-rufous Warbling-Finch, Poospiza nigrorufa based on Jordan et al. (2017), Shultz and Burns (2013), and SACC Proposal 753.
[Thraupidae, Core Passeroidea V, 3.05]

May 19

Elaenias: Based on Tang et al. (2018), I have rearranged Elaenia and returned Chilean Elaenia, Elaenia chilensis, to Sierran Elaenia, Elaenia pallatangae.
[Tyrannidae, Tyrannida II, 3.06]

Furnariinae: I have accepted several splits from IOC and Ridgely/Tudor (2009). Subspecies are allocated as in IOC.

  1. Pacific Tuftedcheek, Pseudocolaptes johnsoni, is split from Buffy Tuftedcheek, Pseudocolaptes lawrencii.
  2. Pacific Hornero, Furnarius cinnamomeus, and Caribbean Hornero, Furnarius longirostris, are split from Pale-legged Hornero, Furnarius leucopus.
  3. Striped Woodhaunter, Automolus subulatus, is split into Western Woodhaunter, Automolus virgatus and Eastern Woodhaunter, Automolus subulatus.
  4. Plain Thornbird, Phacellodomus inornatus is split from Rufous-fronted Thornbird, Phacellodomus rufifrons
  5. Creamy-breasted Canastero, Asthenes dorbignyi is split into Pale-tailed Canastero, Asthenes huancavelicae, Rusty-vented Canastero, Asthenes dorbignyi, and Dark-winged Canastero, Asthenes arequipae.

Baron's Spinetail, Cranioleuca baroni, has been lumped into Line-cheeked Spinetail, Cranioleuca antisiensis. See Seeholzer and Brumfield (2018) and SACC Proposal 762.
[Furnariidae, Furnariida II, 3.05]

Locustellidae: The Grassbirds (Locustellidae) have been rearranged based on Alstrom et al. (2018a). Two species have changed genera: The Fan-tailed Grassbird moves from Schoenicola to Catriscus and the Bamboo Warbler moves from Bradypterus to Locustella. The genera Buettikoferella and Megalurulus have been merged into Cincloramphus. Bowdleria and Eremiornis have been merged into Poodytes. Amphilais has been merged into Bradypterus. Chaetornis has been merged into Schoenicola. Finally, part of Locustella has been separated as the new genus Helopsaltes Alström et al. 2018 (type species certhiola).
[Locustellidae, Paroidea & Sylvioidea I, 3.11]

April 8

Santa Marta Screech-Owl: The recently described Santa Marta Screech-Owl now has a scientific name, Megascops gilesi (Krabbe, 2017).
[Strigidae, Afroaves II, 3.09]

Striped Manakins: Based on Lane et al. (2017), the Striped Manakin, Machaeropterus regulus, has been split into

  • Striolated Manakin / Western Striped-Manakin, Machaeropterus striolatus
  • Painted Manakin / Peruvian Striped-Manakin, Machaeropterus eckelberryi
  • Kinglet Manakin / Eastern Striped-Manakin, Machaeropterus regulus

[Pipridae, Tyrannida I, 3.03]

March 2018

March 15

Tinamous: Hayes et al. (2018) showed that there is no reason to consider the Chaco Nothura, Nothura chacoensis, distinct from the Spotted Nothura, Nothura maculosa. As a result, I now consider the Chaco Nothura to be a subspecies of the Spotted Nothura, Nothura maculosa.
[Tinamidae, Paleognathae, 3.03]

Barn Owls: The Barn Owls have been rearranged based on Uva et al. (2018). Their results suggest that some adjustment to species limits will be needed, but it is not yet clear to me how best to do that.
[Tytonidae, Afroaves II, 3.08]

Owls: Koparde et al. (2018) found that Heteroglaux is embedded in Athene. Thus the Forest Owlet becomes Athene blewitti. This causes a rearrangement of Athene.
[Strigidae, Afroaves II, 3.08]

Gnatcatchers: The Gnatcatchers have been restructured based on Smith et al. (2018). The Yucatan Gnatcatcher, Polioptila albiventris, has been split from the White-lored Gnatcatcher, Polioptila albiloris. The Tropical Gnatcatcher, Polioptila plumbea has been split into:

  1. Eastern Tropical Gnatcatcher, Polioptila atricapilla.
  2. Northeastern Tropical Gnatcatcher, Polioptila plumbea.
  3. Western Tropical Gnatcatcher, Polioptila parvirostris.
  4. Maranon Gnatcatcher Polioptila maior.
  5. Northwestern Tropical Gnatcatcher Polioptila plumbiceps, including innotata, plumbiceps, and anteocularis.
  6. White-browed Gnatcatcher, Polioptila bilineata, including daguae, bilineata, cinericia, brodkorbi, and superciliaris.

A more complete description may be found in
[Polioptilidae, CERTHIOIDEA, 3.04]

February 21

Hypogramma: The genus name Hypogramma is preoccupied, and is replaced by Kurochkinegramma (Kashin, 1978). Thus the Purple-naped Sunbird is Kurochkinegramma hypogrammicum.
[Nectariniidae, Basal Passeroidea, 3.02a]

February 19

Spiderhunters: Based on Campillo et al. (2018), the Purple-naped Sunbird has been restored to genus Hypogramma (from Arachnothera) and is placed sister to Arachnothera.
[Nectariniidae, Basal Passeroidea, 3.02]

February 4

Fluvicolinae: Lopes et al. (2018) found that the Chapada Flycatcher was unrelated to the other Suiriri taxa. Rather, it is sister to Sublegatus. Lopes et al. established a new genus for it, Guyramemua, so the Chapada Flycatcher moves from Elaeniini to Fluvicolini and becomes Guyramemua affine. (corrected)

Oddly, although Lopes et al. specify that Guyramemua is neuter, they persist in writing Guyramemua affinis rather than using the neuter affine.

The Gray Monjita becomes Nengetus cinereus rather than Taenioptera cinerea. The monotypic genus Nengetus was established by Swainson in 1827. The Gray Monjita had historically been in the genus Taenioptera (Bonaparte 1825), of which it is the type (e.g. Catalogue of the Birds in the British Museum). However, although Bonaparte alluded to Taenioptera as a subgenus in 1825, he did not actually establish the name until 1831. Thus Nengetus has priority.
[Tyrannida II, Tyrannidae, 3.05]

February 3

Fluvicolinae: The Fluvicolinae have been rearranged based on Fjeldså et al. (2018). Although their phylogeny seems generally more reliable than what I cobbled together from previous work, some of the nodes are still poorly resolved. I have mostly followed their Figure 2. However, although their work suggests that Empidonax is not monophyletic, I have not made changes to Empidonax due to some weakly supported nodes.

I have carved up Xolmis. To do this, I moved the Black-and-white Monjita, now Heteroxolmis dominicanus, to Heteroxolmis and the Fire-eyed Diucon, now Pyrope pyrope, to Pyrope. I've also moved the Black-crowned Monjita, Neoxolmis coronatus, Rusty-backed Monjita, Neoxolmis rubetra, and Salinas Monjita, Neoxolmis salinarum, to Neoxolmis from Xolmis. Finally, the Gray Monjita, now Taenioptera cinerea, has been placed in Taenioptera.

Finally, there are some splits. Darwin's Flycatcher, Pyrocephalus nanus, the extinct San Cristobal Flycatcher, Pyrocephalus dubius, and Scarlet Flycatcher, Pyrocephalus rubinus, are split from the Vermilion Flycatcher, now called Pyrocephalus obscurus. See Carmi et al. (2016).

Further, the Blackish Chat-Tyrant, Ochthoeca nigrita, and Maroon-belted Chat-Tyrant, Ochthoeca thoracica, have been split from the Slaty-backed Chat-Tyrant, Ochthoeca cinnamomeiventris, based on a combination of Fjeldså et al. (2018), Ridgely and Greenfield (2001), Hilty (2003), and Garcia-Moreno et al. (1998).
[Tyrannida II, Tyrannidae, 3.04]

Shortwings: Based on Kyriazis et al. (2018) and the HBW-Checklist (del Hoyo and Collar, 2016), I've split the White-browed Shortwing into:

  • Himalayan Shortwing, Brachypteryx cruralis
  • Chinese Shortwing, Brachypteryx sinensis
  • Taiwan Shortwing, Brachypteryx goodfellowi
  • Sumatran Shortwing, Brachypteryx saturata
  • Javan Shortwing, Brachypteryx montana
  • Flores Shortwing, Brachypteryx floris
  • Bornean Shortwing, Brachypteryx erythrogyna
  • Philippine Shortwing, Brachypteryx poliogyna
  • Mt. Apo Shortwing, Brachypteryx mindanensis

Yes, the typo has been fixed. The Lesser Shortwing, Brachypteryx leucophris, is also embedded within this clade.
[Muscicapidae, Muscicapoidea II, 3.12]

January 28

Wagtails and Pipits: The Wagtails have been rearranged based on Drovetski et al. (2018) and Harris et al. (2018).

Based on Van Ells and Norambuena (2018), the New World Pipits have been rearranged. Futher, two species have been split and one has been lumped.

  • Peruvian Pipit, Anthus peruvianus, has been split from Yellowish Pipit, Anthus lutescens
  • Puna Pipit, Anthus brevirostris, has been split from Short-billed Pipit, Anthus furcatus.
  • South Georgia Pipit, Anthus antarcticus, has been lumped into Correndera Pipit, Anthus correndera due to very small DNA differences between them.
