Unfortunately these GBTs are first time parents and might end up have one chick reach flying stage, or no chicks. Even sandy-colored chicks laying on sand and parents being aggressive toward SBBGs, are useless against SBBGs"s good eyesight.

Great to see this species nesting in NZ - even if this attempt fails it will still be a historic achievement in the history of GBT in NZ.

Visited the site this morning but just stayed on the edge of the SBBG colony as one of the GBT pair and a Caspian joined in with 60 or 70 SBBG to give me a hurry up. Weather turned really nasty so left them in peace.

Hi all,
Do you think someone should up date the correct name for this bird now that it has been split. Just keeps it all tidy.
Sub species looks clear, macrotarsa.

Great report.

A fortnight following my previous visit I finally managed to return today. It was the first time I encountered people fishing off the end of the spit. A lot of the vegetation appeared flattened and there were tyre tracks close to where the nest was and the nest was empty. The only birds still present were the SBBGs and the pair of Caspian terns. Close to the bridge, about 1 Km west of where the nest was, one GBT momentarily hovered above me as I walked back along the water's edge then it disappeared across the other side of the spit.

Shame on people for disturbing the breeding colony, but next year the parent GBT will breed again.

GBT eggs take 22 days to hatch and chicks start flying at 4 or 5 week-old.

Oh dear how frustrating Glenda. Do you think it’s worth mentioning to DoC so they can ensure people don’t disturb the birds in the future?

Great report.

Hi Steve, are there separate common names recognised for the ssp? NZBO doesn't mention them.

They’ve recently been split by the IOC with macro tarsh now becoming the Australian Tern split from the Gull-billed Tern of south east Asia etc.
