    Bogota skin

    Basically, in the early 1800s (primarily), European and American museums purchased specimens from local collectors in Colombia via some sort of clearing house in Bogota. In many cases, there was no information provided as to where the specimens actually were taken, but it is assumed that it was...

    Turdidae

    Yes, there are Zoobank codes under each newly named taxon. Catharus arcanus sp. nov.: urn:lsid:zoobank.org:act:25B3DB71-FE5E-4FBF-A2CE-8D270CBA7250 Catharus berlepschi nebulus ssp. nov.: urn:lsid:zoobank.org:act:EAE392CC-A763-4E5E-8F6F-68921515C9A2 Catharus opertaneus tenebris ssp. nov...

    Can a species that includes subspecies also stand alone?

    Are you asking: when a formerly monotypic species has a new subspecies named, which population becomes the nominate (receives the same name as the species name)? If so, then the answer is: whichever population is the one that was originally named becomes the nominate subspecies. That is to say...

    Trochilidae

    I can't assess what you, or anyone else, saw... but if it was paler than a White-bellied Hummingbird it certainly doesn't sound like a Taphrospilus! They are more heavily speckled below and so would appear darker overall. If there are seasonal movements (certainly plausible), it would speak more...

    Trochilidae

    Yes, it is at the San Marcos museum in Lima.

    Trochilidae

    Is there evidence to look at? I am not aware of any besides the one specimen. While I was there I saw a lot of Amazilia chionogaster, but never a Taphrospilus.

    Trochilidae

    Well, mostly. Basically, there has been no evidence that this species occurs at Ampay regularly and, assuming the initial specimen was actually collected there (and not accidentally mislabeled), we assumed it to represent an elevational vagrant of T. hypostictus. I think the reason it was...

    Passeriformes

    It is my opinion that Bret has jumped at shadows on this one... the island form of M. maculatus is not appreciably different from nominate birds of the Guianan Shield area in plumage or voice. The last time I discussed the two populations with him, I think he basically agreed that that may be...

    Olive Sparrow and Olive Warbler

    Welcome to the world of common bird names. Don't try to look for phylogenetic signal therein, you will be mostly very disappointed. But it does show how much convergence has occurred in bird evolution when it comes to morphology.

    Olive Sparrow and Olive Warbler

    No, they are all still in the same family. You may be confused because of the recent separation of Passerellidae from Emberizidae, which means there are still a lot of sources that are not updated. In addition, many former members of "Emberizidae" in South America have been shifted to the...

    Olive Sparrow and Olive Warbler

    Maybe, but I suspect it has to do with the fact that no one has called the committees' attention to the issue. Many/most allow proposals from outside the committee to make such corrections, it just requires someone to do it.

    Olive Sparrow and Olive Warbler

    Interesting. Surprising that there has been no effort to have any of the main taxonomic committees accept this change.

    Olive Sparrow and Olive Warbler

    I think you have this a bit confused. Olive Sparrow is part of the New World Sparrow family, Passerellidae, which includes all North American sparrows and towhees (minus the members of Passer: House and Eurasian Tree sparrows. These are the "true sparrows" in family Passeridae). Emberizidae is...

    Olive Sparrow and Olive Warbler

    Is "Arremonidae" a family now? I thought New World Sparrows were Passerellidae. Even if Arremonidae was a family, its type genus would be Arremon, not Arremonops.

    Fringillidae

    It seems this paper, despite the claim of being published electronically as of 17 July, is only available as an abstract on the defunct website of the journal, not on the new one here: https://openornithologyjournal.com/index.php But more interestingly, the lead author is also the journal's...
