The stunningly beautiful Blue Vanga is just one superb example of an overall spectacular avian radiation unique to the Malagasy region. This comparatively small vanga is the only member of the family that is not endemic to Madagascar itself. The nominate subspecies occurs in forested areas below 1,600 m across much of Madagascar, although it is absent from the country’s central plateau and the far south and southwest, with separate races on two islands in the Comoros, Mohéli and Grand Comoro. Despite the species’ striking plumage and general abundance, very few natural history data are available, with just one nest having been well described. In contrast to the situation on Madagascar, the birds on Grand Comoro are at considerable risk, with very few observations since the 1970s. Taxonomists currently dispute how best to deal with the different named populations, some continuing to treat all three as a single species, while others prefer to regard the Comoros birds as representing a different (albeit closely related) species.
