    Clements 2024 checklist update

    I hope there will be a website with a good interface that allows for quick and easy viewing of information concerning taxonomy and nomenclature. I always found the pages of avibase, worldbirdnames and others somewhat clumsy to use.

    Latest IOC Diary Updates

    Ah, so that's the difference. I wonder if there's really a need for these different lists that differ only very slightly...? Same applies to the list with red highlights.

    I can't find any differences between the 'LifeList+' and 'LifeList+full ssp' sheets.

    Has the WGAC published a list?

    I don't think this was posted before (and I'm quite surprised I have apparently not checked the WGAC site since January?!), so here you go... Working Group Avian Checklists | International Ornithologists' Union

    Inaccessible bird species

    I will stick to the number generated by ebird as otherwise I'll never be done with checking information over and over again. Category E is a rather arbitrary one anyways that only highlights the rarest reported species. Some are rarely reported as their ranges are hard to reach others are just...

    Inaccessible bird species

    The following category E species now have more than 10 observations on ebird (number of observations in brackets). Is anyone aware of any reasons why they should not be deleted? Santa Marta Sabrewing (21) Somali Pigeon (12) Manus Dwarf-Kingfisher (13) New Ireland Dwarf-Kingfisher (15)...

    Inaccessible bird species

    I'm updating the spreadsheet: First I need to incorporate the taxonomic changes from IOC 14.1 and 14.2. The following will be added to the spreadsheet. Quite many IMHO: From 14.1 Nicobar Hooded Pitta (Pitta abbotti) Cat D2 White-gorgeted Fantail (Rhipidura coultasi) Cat E Guadalcanal Fantail...

    Latest IOC Diary Updates

    I might be willing to agree with you, but in this particular case new genetic information have nothing to do with the name change, instead there is obviously a change in real-life usage of the name within it's range, as has been pointed out above. I wonder, if Bearded Reedling was changed back...

    Latest IOC Diary Updates

    Until the very last sentence, I was sure this was going to be a statement pro-change. There's just as much reason to change the name as there is to keep it. In the end, I highly doubt it's a matter that will have any significant influence on anyones life here. I am in favour of coming up with...

    Madeira - late July 2024

    Very nice trip report and beautiful pics. Reminds me of my trip last autumn. I wonderwhat the first cetacean pocture shows, as it's neither a Pilot Whale nor a Dolphin. Could it be a Bryde's Whale?

    Procellariiformes

    Looking at the trees it's more of a complete reshuffle than just simply splits. All very counterintuitive given the phenological similarities, but apparently quite well supported

    Procellariiformes

    No, 3-way split for Wilson's, two-way solit for Elliot's and a new taxon within the Pincoya complex. Apparently the Wilson's s.l. have quite different non-breeding ranges

    ABA Big Year 2019

    If I remember correctly the reason is simple: Weigel didn't use ebird during his big years (which was heavily criticized by many ebirders, as he definitely used the platform to gather information)

    Birdwatching in Brandenburg

    You're probably aware that mid-July is not a very good time for birding, so you may miss some of your targets despite being at the right spots. Tiergarten is the spot for Goshawk, but they're not rare anywhere, Hawfinch should be available in pretty much any forest or park with trees. The...

    Extinct vs extant IOC

    While there are some discrepancies to the IOC list, I guess this is basically what you're looking for. https://searchforlostbirds.org/ Otherwise you may want to have a look at the Inaccessible birds thread https://www.birdforum.net/threads/inaccessible-bird-species.435949/

    2024 Taxonomic Changes - Costa Rica Specific Changes

    Nice write-up. Just one small comment. You write that Brown Boobies in the Pacific will become Cocos Boobies and those in the Caribbean stay as Brown Booby. The way I understand it, there's also a large portion of birds in the Pacific that remain as Brown Boobies and only a minority of birds...

    Giant Hummingbird

    I found this blog that had a lot of illustrations that I find quite helpful. I've seen Northern Giant Hummingbird in Ecuador and I've also seen Giant Hummingbird in Peru in August, shere I presume both species occur side by side at that time of year (since it's winter in Patagonia), so I'll...

    The ultimate range maps

    For me the ultimate maps are created by iNaturalist, which for some reason has yet to gain traction among birders. Choose any species you like, go to maps and add the GBIF layer. Doesn't get much better than this IMHO Here's House Sparrow...

    Time calibration and Linnean ranks in birds

    I really love this as a mind game, as it really helps understanding some things. On the other hand, I really don't like some of the outcomes, with the changes to Passeriformes being the worst and having little to no real-life value. The more I think about it, the better I think the current...

    Accipitridae

    I was quite surprised that I had seen no mentions of Goshawk (and others) requiring new genuses (Astur, Tachyspiza, Aerospiza, Microspizias). However, I notice the paper is still only in preprint and has not been mentioned here (albeit having been posted last July already). So here we go...
