Negative Positive
Title: Questionable at best
Review: As long as it sticks to New World vultures, this is a good reference. When it comes to Old World vultures, though, this guy simply doesn't know what he's writing about. He claims, for example, that the Bearded Vulture is incapable of carrying tortoises aloft (which it does regularly), and that the Asian Black Vulture is the largest vulture in Africa (it is the second smallest, out of nine species). I find it disturbing (if not surprising) that the Sierra Club would fund such a poorly researched and blatantly inaccurate volume. Anyone looking for an excellent reference on Old World vultures should check out The Vultures of Africa, by the South African Vulture Study Group.
Is the review positive or negative?
