My latest South Georgian adventure involved a cruise up the coast on board our Fisheries Patrol Vessel to the Bay of Isles. More specifically to Prion Island, in order to see its feathery inhabitants.

Prion Island is home to a small population of the world’s largest seabird, the Wandering Albatross. With a spectacular wingspan of 3.7 metres, a large adult wanderer is roughly the same length as a small car.

Approximately 30 wanderers return to Prion Island every year in December.  They lay a single egg each which will eventually hatch and be cared for by both parents over the year, before hopefully fledging.  Because of the large investment needed to fledge a wandering albatross chick, parents breed monogamously, every two years. This means that the breeding population of the island is roughly 60 pairs.

My job, this visit, was simply to check up on the downy chicks as well as record a number of parameters, such as snow cover and fur seal disturbance, which may effect the success of these giants.

By the time chicks are this developed, both parents can leave the chick in order to forage so I was incredibly fortunate to see a number of adult birds on the colony..

Albatross species forage at sea and are often caught accidentally by long lining fishermen around the world. South Georgia has one of the most sustainable fisheries in the world, with vessels forced to use particular preventative practices that reduce the risk of bycatch of seabirds (seabird bycatch was 0 in 2015). However, as a result of their spectacular size and effortless flying abilities, Wandering Albatross forage for thousands of miles, meaning birds breeding on the islands will be affected by less well managed fisheries across the Southern Ocean. Sadly, as a result of this and also consuming plastic waste, Wandering Albatross populations are falling and they are considered to be vulnerable to extinction by the IUCN.

Once chicks fledge at the end of the year, they will roam the southern oceans in search of cephalopods (squid), crustacean (krill) and small fish until they are old enough to breed, covering up to 120,000 km in a year.

The island is also home to breeding Giant Petrels and Gentoo penguins. With this year’s Giant Petrel fledglings still covering the island, next year’s breeders had already arrived and were already courting and building nests.

Gentoo penguins tend to return to their colonies every evening to roost rather than remaining at sea. As we awaited a pick up on the beach, I was able to put my GoPro in the water and get a glimpse of them in their more natural habitat.

Before rats were successfully eradicated from South Georgia, islands provided the only safe haven for South Georgian Pipits. These small areas of refuge allowed populations to survive allowing recolonisation of the mainland, post rats
