    Scientific name of Common Bush Tanager

    What an interesting puzzle! David Donsker dug into it a bit today and says the following: "Maybe the problem originates with Zimmer. Below is a link to his 1947 paper which lumps C. flavopectus with C. ophthalmicus. Zimmer subsumed the former into the latter without considering dates of...

    Range of Mourning Collared Dove

    Thanks, Richard ... but now you've generated another question. I have failed to encounter any reference to a population of ambigua in sw Angola and nw Namibia. Is this population shown in addition to the birds in e Angola and ne Namibia? Are any notes provided about it? Again, thanks Sally

    Range of Mourning Collared Dove

    Thanks for pointing this out. I'll correct it for the next version. I'm working in a location without many resources so I've got an additional question: Are the ambigua birds in s Zimbabwe, s Mozambique and ne South Africa a disjunct population more northerly ambigua in Angola, Zambia, etc?

    Hawk-Eagles in the Philippines

    Hello Birdforum Does anyone have some first hand or newly published information regarding Pinsker's Hawk-Eagle versus Philippine Hawk-Eagle on Mindoro? Clements, H&M, BLI, Peregrine Fund and IOC (yikes!) are vague or contradictory. Thanks, Sally

    Capitalizing Bird Names

    During the last few years, while working with the IOC team, I’ve spent hundreds of days and thousands of hours working on bird names and ranges. Along with the group, I’ve thought long and hard about and discussed ad nauseam the nuances of punctuation and the structure of names. A few weeks...

    New Capito barbet

    I apologize if this has already been mentioned but, surely, there is little complete about the specimens from which the many fossilized species are being described. The scope of the ICZN code specifically includes fossils (Article 1.2.1). Same rules apply as with extant forms. I hope the ICZN...

    Swifts and Subspecies

    I've been doing some work and some thinking regarding subspecies recently, so I've enjoyed the discussion here. Subspecies sure do encourage closer scrutiny in the lab and the field, don't they? I also enjoy the "work in progress" aspects of our knowledge as well as with the species itself...

    I don't think that this paper has been published and, perhaps, not yet submitted. My husband, Frank Gill, reported that the presentation at the Brazil IOC meeting placed Calyptura as a basal Tyrannid provisionally related to Neopipo and Platyrinchus. Sally Conyne

    Hello All Thanks to this discussion, IOC editors realized that this species was incorrectly placed in Onychoprion (a spread sheet error). We'll move it to Chlidonias with the release of version 2.2 later this month. Sally Conyne

    IOC List 2.1

    The IOC is not proposing these splits.

These decisions are made by groups such as the SACC. The 2.1 updates (based...
