Gruiformes, Ralloidea, Rallidae: Kirchman et al. (2021) provide an updated tribe-level timetree of Rallidae. The study was based on ultra-conserved elements (UCEs) and included one sarothrurid and six rallid species not sequenced before. For the Calayan Rail the authors introduced the new genus name "Aptenorallus". Most importantly, however, they established a revised classification, rearranging several genera to render them monophyletic. [error spotting: 👹 it is pan-Rallidae that originated at 39 Ma, not crown-Rallidae as erroneously stated on page 8; 👹 in the timetree depicted in Fig.4 the genera Porzana s.s. and Gallinula s.s. have been confounded; 👹 the genus name is Coturnicops, not Cotunicops as erroneously stated on page 15]

Note: "CLASSification": I replaced the note „Neglected clades“ by this note in order to transcribe the temporally-banded avian timetree (see Note: "Temporal banding") into a rank-based Linnaean classification. As the temporal banding is restricted to the CLASS Aves, the new classification is referred to as CLASSification.

Note: "Temporal banding": I applied the approach of "temporal banding" to the family-level timetree of Kuhl et al. (2021). As a consequence, several clades currently ranked as orders and families will have to be redefined.

Note: "Temporal banding": As announced, I applied the approach of "temporal banding" to the order-level timetree of Kuhl et al. (2021). I selected two cut-off times (55mya and 65mya), resulting in 43 orders and 10 superorders.

Note: "Temporal banding": I added this note, because the tool will serve to standardise traditional classifications. In addition, I intend to apply temporal banding to avian classification in the near future.
May 10, 2021
Note: "Avian orders": This note is currently under revision, because users of the Avian phylogeny post on birdforum.net made valuable suggestions for improvement that will be incorporated under note: “Temporal banding“.

Galliformes, Phasianidae, Pavoninae, Gallini: Crowe et al. (2020) resolved the nomenclatural uncertainties surrounding both Latham’s Francolin and the red-tailed francolins by restricting the genus Peliperdix to lathami, and by designating the new genus the Campocolinus for the red-tailed francolins. The Phasianidae timetree was adjusted accordingly. [thanks to Jim from France for bringing this paper to my attention]

Psittaciformes, Psittacidae: Based on mitogenomes, Kolchanova et al. (2021) studied the phylogenetic relationships of the five extant species of Amazona parrots occurring in the Greater Antilles. The authors found that these species form a clade that colonized the Greater Antilles from mainland Central America by stepping-stone dispersal and speciation, starting some 3.5 mya. The results didn‘t affect our parrot timetree.

Accipitridae & Caprimulgidae: Sangster & Luksenburg (2021) recognised that the puported mitogenomes of both the Japanese Sparrowhawk (Accipiter gularis) and the Grey or Jungle Nightjar (Caprimulgus indicus), formerly treated as C. jotaka, are artefacts, because re-analysis by the authors showed the published mitogenomes to be chimeras, i.e. mixtures of more than one species. However, our timetrees are not affected.

Galliformes: An overview of the phylogeny of Galliformes is provided by Kimball et al. (2021). The authors built a supermatrix of all publicly available DNA-sequence data. The study covered 264 galliform species representing 88% of the total species number. With only one exception, I follow their results.

Gruiformes: The phylogeny of Rallidae has been adjusted according to the results of Garcia-R. & Matzke (2021). However, since the results are based on total evidence, i.e. combined morphological and DNA data, several proposed relationships must be considered preliminary.

Aequornithes: Following the proposition of Sangster & Mayr (2021), I added the name ‘Feraequornithes’ for
a group comprising Procellariiformes, Sphenisciformes, Ciconiiformes, Suliformes, and Pelecaniformes. In other words, the new clade comprises the same orders as Aequornithes, but without

Individual orders: I updated this section in order to include the latest changes of Kuhl et al. (2021).

Aequornithes, Pelecaniformes: I expanded the Pelecaniformes at the expense of the former Ardeiformes and Plataleiformes, which have been eliminated.

Note: „Neglected clades“: I added this chapter hoping to direct future research efforts towards
some selected clades that have largely been neglected in phylogenetic studies.
November 21, 2020
Strisores: Following Chen & Field (2020), I added the newly coined clade names Letornithes and Sedentaves
to the taxonomy of Strisores. However, I will not follow their suggestions for pan-clade names. (refer to Note: „Pan-clades“ for further information).
November 15, 2020
Note: „Avian orders“: I added this chapter hoping to launch a discussion on the question: What is an avian order?

Palaeognathae: I adopt the phylogeny of Kuhl et al. (2021). However, the reconstruction of the phylogeny of Palaeognathae remains problematic. I guess this is largely due to the fact that, apart from their neognathous sister-clade, relevant outgroups diverged a long time ago, e.g. turtles some 170mya and crocodiles some 150mya.

Higher phylogeny: I adopt the phylogeny of Kuhl et al. (2021) because of both the broad taxonomic coverage (all 106 non-passerine and 115 passerine families) and the conclusive results. The authors found that 3’UTR sequences yielded a well-resolved and stable tree-topology. Their results confirm most previous assumptions.
