Breeding Biology of Brown NoddiesAnous stolidusat Their Southern-Most Breeding Site, Gough Island, in Comparison to Other Sites

Brown Noddies (Anous stolidus) at Gough Island, the southernmost breeding site for this species, exhibit high breeding success rates—81%—and synchronized breeding schedules with other mid-latitude Atlantic populations, suggesting a single meta-population. Egg-laying occurred between 2–12 December, with incubation lasting 37 days and fledging after 46 days, though chicks remained dependent on parents for up to 11 more days. Hatching (88%) and fledging success (92%) were notably higher than at other sites. The study monitored 19 nests over three seasons, measuring growth in eight chicks and six fledglings during the 2005/06 season, revealing similarities in chick size, growth rates, and pre-fledging fasting behavior with noddies from other Atlantic locations.
