Does anyone have a percentage or number to compare with the 93 @Rayane cited Zurich having in total?
Was curious about this myself so did a bit of digging a day or two ago; as far as I can tell there are 12 species:
African Pygmy-goose
Bernier`s Teal
Pitta-like Ground Roller
Madagascar Fody
Crested Drongo
Crested Coua
Malagasy Blue Pigeon
Malagasy Lovebird
Madagascar Crested Ibis
Lesser Vasa
Greater Vasa
Madagascar Partridge
Of these, all but the lovebird, coua, partridge and fody are in single digits, and the ground-pitta and drongo are down to one individual apiece. The fody and partridge comprise something like 80% of the birds there.
