Kia ora koutou (hello everyone)
The Royalcam nest.
Larger chicks can handle warm days more easily; the days are also getting shorter.
Note: NZ Daylight saving time ends on the 6th of April, the clocks will go back 1 hour at 3am on Sunday.
Since hatching at 286g on the 28th of January, the Royalcam chick at Signal Station Trig has grown to 4.4 kg on day 63 (Tuesday 1st of April). This is a 0.3 kg decrease on last week’s weight. Today’s weight is 150g below average for a female but still well within a healthy weigh range. There were quite a few chicks’ weights drop this week which is likely due to recent calm weather.
Weighing is now weekly on Tuesday’s weather allowing and is now a 2-person task using a small basket. A larger basket will be used in coming weeks.

Comparisons of average male and female chick weights and all the past Royalcam chicks are included. Rangers use weight data to determine when a chick requires feeding intervention.
There have been 3 feeds from both parents since the last weigh in. The gaps between feeds are getting longer which is normal.
Feathers are starting to come in underneath the down. They are part of the secondary down structure which will fall off once the feathers are big enough. The black feathers on the wings will be visible first.

On cold days well-fed chicks will be warm with the food that is supplied by their parents and the growing feathers add a further layer of protection.
Satellite Tracking
GLG’s last GPS update was on the 25th of March. She fed her chick on the 28th of March and the 30th of March. The tag did not appear to be present on the 30th of March. Tag loss is expected to happen as the feathers moult.

RLK/A85 GPS is still functioning, and this is his update for the last 7 days.
Four GPS tags on Juveniles that fledged last September are still active.
These are maps of each tag and their last 30 days of activity off the coast of South America.
