2017 seabird updates from Cousine Island

Lesser Noddy breeding success
Breeding success of Lesser Noddy on Cousine are investigated annually during the seabird nesting season, from June to October. A total of 150 nests (divided into 15 different ‘plots’ of ten nests) were selected around the island. The nests were visited weekly to determine the status of each nest, and the contents (adults present, egg, stage of chick) recorded using binoculars and a mirror attached to a long pole.

350 pairs of Brown noddies are estimated to breed on Denis Island

In February 2016 a Brown noddy (Anous stolidus) census was conducted on Denis Island by Green Islands Foundation (GIF) staff and volunteers to estimate the size of the breeding population. Brown noddies are commonly ground nesting but are seen far more frequently nesting in the crowns of coconut trees on Denis Island, possibly due to the presence of mammal predators in the recent past before the eradications of rats and cats.

Following the removal of an introduced species, island restoration can follow two general approaches: passive, where no further intervention occurs and the island is assumed to recover naturally, and; active, where recovery of key taxa (e.g. seabirds) is enhanced by manipulating movement and demography. Continue reading “Deciding when to lend a helping hand: a decision-making framework for seabird island restoration”

Seabird Census Complete

On Cousin Island Special Reserve, Nature Seychelles staff and volunteers complete two main seabird censuses annually, coinciding with the two different monsoon seasons. At these times censuses are conducted for the year-round nesting birds, such as White-Tailed Tropicbirds (Phaethon lepturus), Tropical Shearwaters (Puffinus lherminieri), and White Terns (Gygis alba).
