Introduction
The relationships within the Pyrrhura species complex are partly unresolved. In this study, a comprehensive phylogenetic analysis of the Pyrrhura picta-leucotis complex was carried out, covering all species except P. subandina.
Material and Methods
We made a morphological analysis of 745 preserved specimens of all the taxa in differen...

The order Polycladida comprises a highly diverse and cosmopolitan group of marine turbellarian flatworms. Owing to the great morphological diversity and the absence of a molecular phylogeny, the classification of this group has always been controversial. Here we seek to add resolution by reporting the results of molecular phylogenetic analysis base...

... It has been used by MW before for a phylogenetic reconstruction of many other bird taxa, including parrots (Kraus & Wink 2015). The PCR (polymerase chain reaction) amplifications were performed in 50 µl reaction volumes containing 1 × PCR buffer (Bioron, Ludwigshafen), 100 µM dNTPs, 0.2 units of Taq DNA polymerase (Bioron, Ludwigshafen), 200 ng of DNA and 5 pmol of primers for cytochrome b (as described inArndt & Wink 2017). Thermal cycling involved five minutes at 94°C, followed by 35 cycles of 40 seconds at 94°C, 40 seconds at 52°C, one minute at 72°C and a final extension at 72°C for ten minutes. ...
Philippine taxa currently assigned to Blue-backed, Azure-rumped or Müller's Parrot Tanygnathus sumatranus are distinctive both morphologically (larger bill, red vs. pale yellow iris, royal blue vs. glossy turquoise-blue rump, paler green head and duller green underparts; and males having darker green mantles and no blue on the carpals and scapulars) and genetically (as distinct from Indonesian T. sumatranus as T. lucionensis is from T. megalorhynchos). We therefore propose T. everetti (with subspecies burbidgii and freeri; race duponti synonymised with nominate) to be elevated to species rank with the name Blue-backed Parrot, leaving Indonesian T. sumatranus (with subspecies sangirensis) as Azure-rumped Parrot. The taxonomic status of T. e. burbidgii (Sulu Islands) and T. s. sangirensis (Talaud Islands), both notably larger than their respective nominates, deserves study.
... Seiner Revision des P. picta-leucotis-Komplexes sind allerdings nur del Hoyo & Collar (2014) gefolgt. Für die nun vorliegende Studie haben Arndt & Wink (2017) 745 Exemplare in Museen nahezu weltweit untersucht, mtDNA (cytb) der meisten Taxa sequenziert und in begrenztem Umfang auch Lautäußerungen (meist Flugrufe) ausgewertet. Auf der Basis dieses Materials legen sie eine überarbeitete Revision dieses Artenkomplexes vor. ...
... Dem BSC wird dieses Vorgehen allerdings nur in wenigen Fällen gerecht. Nach Arndt & Wink (2017) lassen sich die Sittiche des Pyrrhura picta-leucotis-Komplexes genetisch in sechs Gruppen mit insgesamt 15 Spezies gliedern: I. P. amazonum Hellmayr, 1906;P. pallescens Miranda-Ribeiro, 1926;II. ...
This report is the thirteenth of a series and presents the results of a comprehensive literature screening in search for new bird taxa described in 2017, namely new genera, species and subspecies worldwide. We tracked names of four new genera, eight species and eight subspecies new to science, which were correctly described according to the International Code of Zoological Nomenclature. The new genera are within Trochilidae, Leiotrichidae, Muscicapidae, and Thraupidae. One each of the new species refer to Trochilidae, Strigidae, Psittacidae, Pipridae, Rhinocryptidae, Meliphagidae, Muscicapidae, and Thraupidae; three belong to Passeriformes, the remainder to Non-Passeriformes. New
subspecies were named within Apodidae (2), Accipitridae (1), Psittacidae (3), Paradisaeidae (1) and Aegithalidae (1). One new genus (Remsenornis, Thraupidae) fell in synonymy immediately after publication and another new genus name (Elliotia, Trochilidae) is preoccupied by an older genus name for a beetle und thus not available. The description of one new parrot species (Amazona, Psittacidae) most probably is based on aviary-bred hybrids. In several cases, the populations in question now considered to represent a new species were known since long (in genera Megascops, Myzomela, Sholicola). However, only substantial studies of type specimens of related species, songs, genetics and/or ecology led to description of new formerly unrecognized species. The descriptions of most new taxa concern the Neotropics (two genera, five species, three subspecies), Indo-Malaya (two genera and species each) and Austral-Papua (three new subspecies). The distributional areas of new species often are minute, consequently also the size of the populations concerned. Due to their limited ranges, species new to science are often already endangered when detected or newly defined. In a sequence by genus/species/subspecies, the newly described taxa have the following origins: Palaearctic (-/-/1), Neotropics (2/6/3), Indo-Malaya (2/2/1), and Austral-Papua (-/-/3). Multiple splits of widely distributed species refer to Southeast Asian swifts (Collocalia) and Atlantic/Pacific terns (Thalasseus). We suggest possible flaws in new descriptions
and certain splits regardless of the species concept addressed.
... These individuals may represent intergrades with nearby populations that have varying amounts of bright or dark red on the forecrown (P. r. parvifrons, P. r. roseifrons, or P. orosaensis; Arndt 2008, Arndt andWink 2017). Further sampling and genetic analysis of these populations is needed to sort out taxonomic relationships. ...
The Grey-breasted Parakeet (Pyrrhura griseipectus) is a globally endangered Psittacidae endemic to the Brazilian Northeast region. It has been recently recorded only in the state of Ceará. We report, however, the occurrence of Pyrrhura griseipectus in the state of Bahia based on photographic records, videotaping, audio recordings and reports of the local communities. We also discuss initial data on habitat use and natural history in the new sites in Bahia, besides implications for conservation. We also report observations of P. griseipectus in mangroves and restinga, as well as in abandoned coconut plantations, habitats still not recorded in the literature as habitats of the species. Interactions with plant species are described, including their use for feeding.
