I recently noticed that the white-winged tern is marked as “introduced” in New Zealand in like 20+ checklists (but bizarrely not on the New Zealand checklist itself) with no evidence to suggest that they are introduced. I’ve done a lot of digging and I can’t find anything online that suggests that they are introduced in New Zealand, instead they are considered vagrant. I also find it unusual that anyone would “introduced” a species of tern in the first place, it’s not like people eat them or anything. The only reason I’m not changing it myself is because this seems like a lot of effort, so whoever did it must have had a reason, and so I’m unsure if there’s some hidden knowledge about this that I don’t know about that prove that White-winged terns are “introduced” in NZ??
It’s marked as introduced on the following checklists:
- Auckland
- Canterbury
- Hawke’s Bay
- Manawatu-Wanganui
- Nelson
- Northland
- Taranaki
- Waikato
- Wellington
- Christchurch
- Franklin
- Kapiti Coast
- Napier
- Nelson, NE
- Selwyn
- South Wairarapa
- Waimakariri
- Canterbury Region rough outline
- Canterbury Regional Council
- Christchurch District
- Christchurch sandy beach and estuary,
- East Coast Palmerston to Bluff
- Greater Christchurch City area
- Kaitorete Spit
- Kauri Kingdom
- Lake Onoke
- New Zealand Zone
- North Island
- South Island
- Te Waihora/Lake Ellesmere
- Waimakariri River Regional Park
- Wellington Region Coast
Do any curators know what this is about?
