Mauritius January – July 2013, Rodrigues, Ile Aux Cocos

The other major place of interest for birders in Rodrigues is Iles aux Cocos, not because it hosts any endemics, but because several thousand terns breed here. The current estimate lies around 45.000. Sooty Terns, Common White Terns, Common Noddies and Lesser Noddies use this island and the neighbouring Iles aux Sables year round to breed and rest. Although they have a peak from September to November. We however visited in June and still saw plenty of individuals of both species with ease. When visiting in the arctic winter however, much more waders will be around than the single Whimbrel we observed.

Iles aux Cocos is open for public and can be reached by a one hour boat ride from Baie du Nord. Be prepared to wade the last few km to the islet, for the waters are very shallow around it. Several boat men and tour packages are available and a list of all boat men can be obtained in the tourist office in Port Mathurin. We used James (002308750557) from Rodrigues Vacances and paid 1.000 MRU including landing fee, lunch, drinks, pick-up and drop-off. We found this to be a fair price and were happy to pay this for the tern spectacle, which I didn´t want to miss.
