The Royalcam nest.
Enjoy this short video of GLG arriving at the nest on the 8th of December. She has now been on the nest for 9 days.
Royal Albatross Returns To Take Over Incubation Duties
Changeover times can be around 2 weeks, adult albatross are perfectly adapted to going without food for this time.
Changeover times longer than 13 days are managed by the ranger team.
The Royalcam pair will receive GPS tags.
Geo Positioning Tags are very light weight and are cable tied to the strong back feathers between the wings. They will fall off after around a year when these feathers are moulted. We will receive the data via satellite so do not need to retrieve the device to see the information that it has gathered of the bird’s whereabouts.
Each parent will be tagged while on the nest. The egg will be placed in the incubator during the process and returned once the adult is settled on a dummy egg on the nest. We hope to gain foraging location insights from the data. Updates of their foraging tracks will follow once the next changeover has occurred. RLK will also have some band maintenance done while being handled for deployment of the tracker.
Today's GPS tag update of juvenile toroa from Pukekura tagged 25th of September and 5th of October 2024. They fledged between the 27th of September to the 14th of October 2024.

Thanks to the generous donations on the Otago Peninsula Trusts give-a-little page we can share the tracking of 10 juveniles including the orphaned Top of Bluff Track.
The starting point was at Pukekura, Dunedin, New Zealand and they have travelled across the south Pacific Ocean to the waters of South America.
They will not make landfall until they return to Pukekura in 4 to 10 years’ time. The five males and five females were 230 to 264 days old at fledging. The distance across Te Moana-nui-a-kiwa | Pacific Ocean, is over 9000 km.
The Top of Bluff Track orphans tag had been functioning well, but we have had no further updates from this tag since early December. An analysis of the tag track data will be carried out to determine likely causes of tag failure. It is possible that he has not survived. The 9 other tags all off the coast of South America continue to function well.
The return rate of adolescents at 5 years of age (approximately) is up to 30% of the number fledged in any given year.
In other news, Amīria, the Royalcam chick from 2018, has returned to Pukekura and has been banded YA43.
