About These Birds
Japanbrillenvogel
Der Japanbrillenvogel ist in ganz Ostasien ein vertrauter Gartenvogel und wird in Japan, wo er „Mejiro“ genannt wird, besonders geschätzt. Diese geselligen Vögel bilden außerhalb der Brutzeit Schwärme und sind wichtige Bestäuber von Pflaumen- und Kirschblüten. Auf Hawaii eingeführte Populationen sind allerdings invasiv geworden und konkurrieren dort mit einheimischen Kleidervögeln.
Bioko Speirops
The Bioko Speirops is a vulnerable white-eye endemic to the montane forests of Bioko Island, Equatorial Guinea. It has brown-olive plumage without the typical white eye-ring of most white-eyes. It forages in forest canopy for insects, nectar, and berries, and is threatened by habitat loss and its very restricted island range.
