This new study identifies 39 separate avian colonisations of New Zealand and 11 in situ “radiations” consisting of two or more descendant species present upon human arrival, the largest being the Moa (9 species) and the NZ wrens (7 species). In total, 30 species of the focal group have gone extinct since humans arrived, spread across 15 colonist lineages, 12 of which lost all of their descendant species.
