Hi,

Know nothing about gulls from NZ, so some help appreciated.
Photo taken somewhere in the North Island, November 2006

Thanks

Thanks.
One question though: In some of them the bill is quite bright red, but in others it is very dark, is this due to age difference?
 
Cheers Andy, wasn't aware of that. Can't keep up with all the taxonomy merry-go-round!!
Yes, Luis, juveniles have a darker, brown, bill.
cheers
 
We only have three gull species, Red-billed (common thought declining), Black-billed (Endangered Inland gull) and Black-Backed (Common).

You see the odd black-bill at the coast, so I check though gull groups for them when I go places. Where i live though they are common for a few weeks then they leave.

You only have 2 now according to the IOC list which just lumped Red-billed with Silver Gull as mentioned in my previous post.

Sorry, we do have 3, Black-billed gull (Larus bulleri), Red-billed gull (Silver Gull) (Larus novaehollandiae), and Black-backed gull (Larus dominicanus ).

Silver Gull as Red Billed has been the same for a long time!
