5 thoughts on “New Zealand Pigeon (Hemiphaga novaeseelandiae): Revise global status?”
The following comment was received from John Innes via email [with Carpenter et al. 2021 attached]:
Here are some data for NZ pigeon Hemiphaga novaeseelandiae (kereru) showing South Island decline but only to ca year 2000. I suspect that these data are outside the recent 3-generation period. Recent accounts of kereru increases are from primarily urban counts and may not represent the situation in back-country. There is a new national Atlas survey going on now that will resolve this somewhat, but you won’t get these data in time for the reviews you are doing now. The species is definitely widespread still. I haven’t worked your criteria through in detail. Given the documented SI declines in Carpenter et al., I would recommend retaining Near Threatened until the new Atlas data are available.

Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested by so many people in commenting. The window for consultation is now closed and we are unable to accept any more comments until 21 February 2022. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’s Red List status on this page on 21 February 2022, when discussions will re-open.
Based on available information, our preliminary proposal for the 2022.1 Red List would be to adopt the proposed classifications outlined in the initial forum discussion. In recognition of the comment above and the uncertainties associated with trends away from urban areas, the overall population trend has been changed to ‘Unknown’.
There is now a period for further comments until the final deadline on 27 February 2022, after which the recommended categorisations will be put forward to IUCN.
The final 2022.1 Red List categories will be published on the BirdLife and IUCN websites in July 2022, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisations to be put forward to IUCN
The final categorisation for this species has not changed. New Zealand Pigeon is recommended to be listed as Least Concern.
