Sorry, but it is -- or at least, can be. Experts on crows do not get to decide what we call groups of crows. Not even experts on language do -- English lacks a governing council, so it's a murder of crows if most people agree that it's a murder of crows. This point is conceded at the end for "pack of wolves" and "pod of dolphins", which have entered common usage. Maybe the others will or won't, but it won't be up to zebra experts to decide if it's a dazzle of zebras, or simply a herd.
