Approaching the Errera Channel is a scenic, narrow waterway between Ronge Island and the Arctowski Peninsula on the mainland. It was discovered by the Belgica expedition and named for the Professor Léo Errera of the University of Brussels, a benefactor of the voyage. Errera is home to Danco and Cuverville Islands. Cuverville Island supports one of the largest known gentoo penguin colonies. This can be apparent from miles away, given the right wind direction. Early in the season, snow cover impedes bbut doesn't stop penguins accessing their nests and an intricate network of "penguin highways"is carved into the snow.
Up from the rookery at Cuverville, steep cliffs lead to the island top (seem here ) The cliffs are also home to skuas that are vigorous in defending their well-hidden nests.
