New Zealand Pigeon (Hemiphaga novaeseelandiae)
Hemiphaga is a genus of large pigeons from New Zealand. The two are traditionally considered conspecific, but in 2001 it was proposed that Hemiphaga chathamensis should be considered a separate species instead of a subspecies of Hemiphaga novaeseelandiae. It is here listed as a species, although few authorities outside New Zealand have followed this.
