    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

    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.

    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    I am glad I am not learning German animal names with this book as they are full of errors and outdated names.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...
