New Zealand Bird Help (3 Viewers)

[Purple-Naped Nathan]

First, I got to take the Milford sound cruise and saw a few interesting birds. I think I know what a few of them are but I want confirmation as they'd be lifers.

White Fronted Tern?


Silver Gull or Black Billed Gull?



Mysterious Shearwater



From the Mirror Lakes - Hoping this is good enough to be pure Pacific Black Duck


Lake Gunn Nature Walk
For me this was the strangest one. I found nothing similar to this in a guidebook. I wasn't even sure if it was a bird at first. Looks almost parrot-like. But I'm not aware New Zealand has any white colored parrots. I do have a behind angle if that helps.



Thanks for the help!

Tern ok

105 left and 2nd from right look like silver (slightly darker mantle, fairly extensive black wings tops, red bill on lh bird.

93 looks like black billed (dark bill, faint black tips, near uniform uppers)

Screenshot looks like a possum

The Pacific Black Duck looks pure; I can't see evidence of partial Mallard ancestry.
