THis sounds as if cepediana and ornata are on the verge of taking over
anyway, wheather helped by humans or not. Is or was there any other barrier
between the species?
Also, I would think guimbeaui-juveniles, due to their greyish coloration
would be better hidden then the more showy ornata and cepediana juves. On
green sugercanes (or banana's for that matter) the grey guimbeaui's would
stand out, of course, but I thought that in the habitat you described the
guimbeaui'slived on trees?(with bark for the juves to hide in). Why can the
cepediana and ornata's take over? You have any idea?
