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.
