Site description (2015 baseline)
Cape Jules is a rocky peninsula of ~1 km in length and across, indented by a prominent cove on its northern coast. It is situated ~8 km west of the Zélée Glacier Tongue and ~18 km east of Cape Bienvenue in Terre Adélie.
The IBA qualifies on the basis of the Adélie Penguin (Pygoscelis adeliae) colony present and comprises all of the ice free area at Cape Jules.
The nearest permanent station is Dumont d'Urville (FRA), ~40 km to the west at Pointe Géologie.
Key biodiversity
Barbraud et al. (1999) counted 41 559 breeding pairs of Adélie Penguin at Cape Jules in 1997/98. This compares to approximately 56 399 breeding pairs (95% CI: 34 446, 92 123) of Adélie Penguin at Cape Jules as estimated from February 2011 satellite imagery (Lynch & LaRue 2014).
The Barbraud et al. (1999) survey also recorded 93 pairs of Snow Petrel (Pagodroma nivea), two pairs of Cape Petrel (Daption capense), 46 pairs of South Polar Skua (Catharacta maccormicki) and confirmed Wilson's Storm-petrels (Oceanites oceanicus) as breeding.
Non-bird biodiversity: None known.
