“I found a greater crested tern on our beach – it is ringed with a metal ring on the left leg and yellow plastic ring on the right leg. I haven’t managed to catch it so I don’t know the ringnumber, but I was wondering whether anyone of our fellow Seychelles’ birders remembers ringing a greater crested tern? It’s nice to know that it is currently hanging out on Denis!”
Janske van de Crommenacker, the Island Environment Manager on Denis Island spotted the Greater Crested tern (Thalasseus bergii) a few weeks ago. This is a large tern has a rather shaggy black crest and a heavy yellow-green bill. It is grey above an white below and has a forked white tail.
When feeding, these birds dive into the water to catch their prey such as fish and squid. They also pick turtle hatchlings off the water surface.
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.

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).
