Wandering albatross chick ringing- they're so grown up!


It seems a long time ago that I was visiting the Wanderer study area every day awaiting the arrival of the first Wandering albatross egg, which finally arrived on the 12th December 2012. The eggs are extremely hefty weighing in at around 500g, so not surprisingly the birds that emerge from them turn out to be very large indeed. The chicks spend the winter months being battered by snow, wind and rain hunkering down on their nests, awaiting the next meal brought back by one of their devoted parents.  By mid August the chicks are large enough to be ringed and receive their very own metal ring with a unique seven digit number that will identify them for life. The chicks in the main study area also receive a darvic, which is a plastic coloured ring with three digits on it. The reason for this is that at fledging time I have to visit the study area daily to see when each chick fledges. With the darvic rings I don’t have to get too close to be able to see who is who, thereby minimising disturbance to the birds. They live up to their name of wandering albatross, as just before fledging they leave the nest and can walk fairly big distances to find the best spot for takeoff. It really helps to have the darvic rings to avoid confusion.

In mid-August I got out the ringing pliers and what looked like far too many rings and began. There are just fewer than 500 chicks to ring this year, which does sound a lot, but 20 years ago there were at least double this number.  Ringing can only be done on dry days, which on Bird Island aren’t all too common, so although it is now approaching the end of September I still haven’t quite finished. Ringing an albatross chick is a whole different ball game to ringing the smaller birds I was used to before I came to the island, but you soon get used to it. The chicks definitely have their own personalities, with some being very placid and barely batting an eyelid, whereas others are feistier and peck you in the legs/bum while you are getting the ring on. However once the ring is on most of them have a little shake and flap and settle back down on the nest. Every single chick on the island gets a ring, so Jerry (penguin man) has been helping me ring chicks in the further away areas of the island.

I’m saving a few chicks for when my replacement Jess arrives in just under seven weeks. I will need to train her in how to handle these big chicks ready for her to do it all again next year.

The chicks are now losing their fluffy white down, and their dark grey body feathers and white faces are coming through. Over the next few years they will become as white as their parents. They will spend the next few years at sea, wandering the oceans going as far away as Australia, South Africa, and South America. Some have even been known to make full circumnavigations of the globe, which we have learned from putting geolocators on them. Hopefully I’ll get a few more back this year so we can see where they have been.
