    Diederik or Dideric?

    Given that Didric is the French version of Diederik, it makes sense he wrote it that way in his description. As the boers had arrived long before 1806 it is most logical that Diederik is the original name

    Help with this deer from Brazil (Pantanal, Mato Grosso)

    Looks like a red brocket.

    Seals? Alaska, recently

    These look like Steller's sea lion to me with their bulky heads. It can't be much else anyway.

    What is a species?

    The one benchmark of speciation is that there are no benchmarks and it makes no sense to use a blanket one for genetic differences or time of separation. Nature is far too complicated for that. Btw your 10 mya example is more often used for splitting or lumping genera than species. Many good...

    Field Guide to Birds of Greater Southern Africa

    Keith Barnes mentioned on his Facebook that a standalone guide for Angola is already in the works, hence its exclusion here. As Angola is generally not visited in the same trip as the other Southern African countries (where cross-border trips are more the norm), that does make sense.

    Which Lesser Galago in Rwanda

    Should be northern lesser galago ssp sotikai.

    Shrew, Switzerland / France (Sorex, Crocidura sp. ?)

    Yep Crocidura russula too.

    Shrew, Switzerland / France (Sorex, Crocidura sp. ?)

    I don't see any red teeth and the general colouration looks good for Crocidura russula.

    Best guide(s) for European fledglings and juveniles

    The "Handboek Europese Vogels" by Nils van Duivendijk should cover that gap, it is currently only available in Dutch, but given your user name that could be fine, if not an English translation is in the works.

    Lynx Edicions - What Next ?

    I am glad I am not learning German animal names with this book as they are full of errors and outdated names. Noticed quite a lot of errors in the Spanish bovid names too (basically everywhere where a lump occured). Why does the entire HMW series feel so rushed that such errors just keep popping...

    Lynx Edicions - What Next ?

    I ended up buying All the Mammals of the world , mainly for the new primate illustrations (so much better) and the proper bovid taxonomy, as well as to see what has happened since HMW was published. While the book looks stunning it seems it has suffered from the same errors as the original...

    Lynx Edicions - What Next ?

    Nopes, the illustrated checklist still listed (basically) all the bogus Bovidae splits, the current book follows the mammal diversity database which doesn't accept these splits.

    Lynx Edicions - What Next ?

    More then 10 years too late, but better late then never... I know it won't happen, but if they would rerelease volume 2 with sane taxonomy and volume 3 with the new illustrations, I would exchange my original copies in a heartbeat...

    New edition of Fågelguiden (Collins Bird Guide).

    That is my issue with a number of bird guides and identification books. Like it or not, but these introduced species are here to stay and far more likely to be encountered than a bobolink or Pechora pipit in Europe.... They are part of the local avifauna and keeping up to date with their...

    Paintballs to be shot at fearless Dutch wolves

    Some more background. This is a privately owned national park of approx 5000 hectares, which is completely fenced. It used to be connected to other parts of the Veluwe, but these corridors were closed once wolves arrived in the country. This is obviously bad news for wild boar and red + roe...

    Handboek Europese vogels

    Received my copy too yesterday and this book really is something else. There is an insane amount of (advanced) knowledge in this book, but with a smart lay-out that makes the ID features easy to understand. It really is a pity that it is too bulky to take into the field. I too miss the maps...

    Mystery Bird of Prey, Nairobi KE

    Thank you, that might fit indeed. Feels foolish to be fooled by such a relatively familiar species. But going through online images, their posture is quite often not classical, which completely changes their appearance...

    Mystery Bird of Prey, Nairobi KE

    April 2016 I photographed this bird of prey in a garden just west of Nairobi at an altitude of roughly 2000 metres. It clearly is not one of the resident Mountain Buzzards, but it's real ID has puzzled me. I initially identified it as a Steppe Buzzard (Buteo buteo vulpinus), but this ID has...

    HBW and BirdLife Taxonomic Checklist v6 (December 2021)

    Where do you find all those splits/changes? In the excel documents I download there are only 39 rows on the changes tab.... Only Galliformes, Gruiformes and Caprimulgiformes seem covered...

    E readers

    I have used a field guide once on my e-reader (a pdf file), but while it is possible, it is a pain in the ass compared to a tablet, as navigation is much more tricky, zooming is more tricky and the quality of the b&w pages is much lower. So would not recommend it...

    Field guide recommendations for dragonflies and butterflies needed

    For butterflies I am very happy with the Collins guide from Tolman & Lewington, which seems to pack in more information than the haahtela guide. It has served me very well across Europe.

    Lynx's Checklist of Mammals of the World - my two cents

    I think we are more or less on the same line here, I don't believe in true species concepts either and would always argue for presenting multiple lines of evidence. The BSC in a way is a good species concept in the sense that if different populations cannot interbreed they for sure should be...

    Lynx's Checklist of Mammals of the World - my two cents

    That there is data in the Ungulate Taxonomy book (which I also own and have studied in detail) doesn't mean that the data in there supports all the splits, far from it... Many splits (Klipspringers are the easy example) are not supported at all by the data and it is made worse that the relevant...

    Lynx's Checklist of Mammals of the World - my two cents

    I disagree, the level for accepting splits is extremely inconsistent in the literature and as they have just copied the literature there is a gigantic inconsistency in the new checklist as to what is a species (and many bovid splits in the current checklist aren't even supported by data). That...
