    The wingspan of the Bucorvus leadbeateri isn't correct. In stead of 5.6 m. It should probably be something like 1.5 m

    Rob de Ruiter commented on an older version of Crested Porcupine:

    In this article a gestation period of 66 days is mentioned. This seems rather short to me. In the articles of "Bibliotheca Alexandrina" and "Animal Diversity Web" a gestation period of 112 days is mentioned. Only one of them can be true. But which one?

    The dutch preferred name "Amerikaanse oehoe" is not the "Bubo scandiacus" but the "Bubo virginianus"
