This week started with our usual routines and turned into the best “fieldtrip” ever. We cruised through our work of counting penguins and weighing chicks and then we saw a wonderfully calm weather window. We had an extremely favorable, gentle forecast, which allowed us to make a special trip out to the Joubins – a special group of islands that our field team only has the opportunity to see once or twice a year because they are located outside of our boating limits. We packed two boats as a safety precaution and sailed westward.

The krill was thick and the ocean was pulsing with hungry predators. We spotted a humpback whale on our journey out, shortly followed by hundreds of crabeater seals and numerous penguins swimming around. Crabeater seals have very specialized teeth, which enable them to filter the ocean water while devouring krill. Some crabeaters were in the water while many others were laying on the large pieces of ice that drifted past us. There was even a leopard seal in the area, which could’ve been bad news for the “crabbies”. The much bigger leopard seals will eat crabeater seals given the right situation.

We made it to our first study island and were pleasantly greeted by Adelie, chinstrap, and gentoo penguins. This island was particularly fascinating with all three of these penguin species breeding together in the same colony. Many of the chicks were quite young but looked healthy.

Throughout the day, we continued to explore island after island, surveying nesting birds and taking in the unblemished beauty of this Antarctic paradise. As the day came to a close, we packed our boats and made the journey home through gentle seas safely back to the U.S. Palmer Station.

In our local area, the giant petrel eggs have been hatching and there are some excited parents! The chicks are darling fuzzy balls of fluff. Their cooperative parents take excellent care of them and allow us to do our measurements with no complaints. When we return the chicks, the parents snuggle them under the safety of their bodies.

The gentoo chicks are still small but growing quickly, and most of the Adelie chicks are huge. The Adelie parents are incredibly busy trying to keep the begging chicks full. During the upcoming weeks we should start to see the Adelie chicks venture away from their parents into little chick groups within the colony. They will also start to lose their down.

Thanks for reading; I will report back soon.
