Lesser Noddy Anous tenuirostris migration from a non-breeding area in the northern Maldives to a breeding site in the Seychelles

The Lesser Noddy Anous tenuirostris occurs in large numbers in the northern Maldives during the northeast monsoon season (December to April). These birds do not breed in the Maldives, but their breeding site(s) are unknown. We attached GPS Argos satellite transmitters to seven Lesser Noddies roosting on Gallandhoo Island (Haa Alifu Atoll, northern Maldives) on 25 March 2022. Only one transmitter provided data, but it tracked the migration of one Lesser Noddy to the Seychelles, where the bird first roosted on the island of Poivre before moving to the large nesting colony on Cousine. The tracked bird departed the Maldives on 02 April and arrived in the Seychelles on 10 April, covering approximately 2400 km in eight days. Our results highlight the potential benefit of enhanced cooperation and knowledge exchange between the Seychelles and Maldives for improving conservation of Lesser Noddies in the Indian Ocean.
