some observations from the Bishop Museum: "generally vilified for its noisy habits, "quarrelsome" and opportunistic nature, disturbance to domestic pigeons, fruit-eating and nest-robbing habits, and the possibility of its adversely affecting native bird populations". Also, a song "about as musical as a cat-fight". And, somewhat mysteriously, "later writers again castigated the myna in Hawaii, pointing out its role in spreading noxious weeds including Lantana, serving as a host for parasites and avian diseases, predating seabird nests, setting buildings afire with lighted cigarettes, and perhaps competing with 'o'os for cavity nest sites". The Myna has even managed to make the list of 100 of the world's worst invasive alien species (the list has only three birds, and two of them are presently in Hawai'i).
I guess success breeds contempt. As an occasional visitor to the islands I don't have anything in particular against the bird, other than knowing of its possible impact on native species, which is debated. They are ubiquitous and loud, but also intelligent and comical. They were introduced to the islands in 1866 in an effort to control an insect pest, the Cutworm Moth. Apparently they did so, but once the pest was under control, they started to eat everything else and spread widely.
But really, aren't they just so cute?
