Sustaining all life on Earth
“Since time immemorial, we have used wild plants and animals for our most basic needs: from the air we breathe, to the food we eat, to the materials we use for shelter and comfort. The human well-being and prosperity that is derived from the direct exploitation of wildlife, habitats and ecosystems should not be to the detriment of the building blocks of a rich and diverse biosphere.”
|– Ivonne Higuero, Secretary General of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora), World Wildlife Day, March 3rd 2020.|
|For the custodians of Bird Island this all starts with preserving the natural environment, something they have been doing since the lodge opened in the 1970s. With the creation of the Bird Island eco-lodge and its conservation work, the protection of the island and the natural wildlife could be ensured. Today, Bird Island is home to a thriving seabird colony of Sooty Terns, sea turtles that nest on the island’s shores, along with other amazing wildlife. Visitors to the lodge are able to experience this whilst the livelihoods of many are maintained. We hope that Bird Island continues to serve as a guide in the balance between man and the natural environment.|
Now, what’s been happening on our little island? Read on to find out.
It has been a very busy turtle nesting season here on Bird Island. These lovely creatures were emerging almost every day with this activity only slowing down about a week ago! We were lucky to have an extra pair of hands during this time from volunteer Sam Cooper, whom we welcomed to our shores after Bea Barclay’s departure in December. Like Bea, Sam is a budding naturalist. After visiting the island last year following a stint with Global Vision International on the main island of Mahé, Sam kindly offered his services during this monitoring period. Sam has been a welcome addition to our team, patrolling the island up to four times a day during the peak of the nesting season.
|What do the numbers say?|
From the data collected we can see that in the 2018/19 season the Green turtle nesting numbers were exceptional. Between the period 21st August and 5th March we recorded 146 nests whereas in the same period of the 2019/20 season just 29 were recorded. This does not reflect the entire monitoring period but is a good indicator that the 2018/19 season was definitely a peak year. In comparison, the Hawksbill numbers are relatively similar from year to year. Nests recorded between 21st August and 5th March of 2018/19 were 254 and 273 in the same period of the 2019/20 season.
|Memorable turtle encounters|
As we all know wildlife can sometimes find themselves in distress. A female turtle found herself in such a situation not long ago where she had completely wedged herself into a bush far inland, at the northern point of the island. On approach we feared that she had already perished since her head was drooped and was motionless. With a bit of determination however, we gained access to her and proceeded to try and free her from her predicament. We kept her cool with a regular dousing of sea water whilst doing our best to clear a path for her out of the bush. The rescue took almost an hour but she finally found her way back to the sea. We’d like to thank our Conservation Officer’s daughter, Isla Rose, who was on hand to run up and down the beach and continuously re-fill a bottle with sea water for the turtle. We felt truly rewarded a few days later when we encountered the same turtle nesting in a much more sensible spot on the island’s West Beach.

Sea turtle survival
Did you know that turtle nests sometimes have to be relocated? Valid reasons to relocate a nest include the threat of erosion by wave action, constant flooding, predation of a nest by crabs and disturbance of a nest by human activity or in some cases other wildlife. For example, we recently had a case where a nest was accidentally dug up by another nesting female. We have had to carry out a number of emergency relocations in the last month for these various reasons. This is a very important part of the conservation work on the island, where intervention by us is required if the eggs are to survive until hatching. Most recently, an entire nest of Green Turtle hatchlings emerged from a nest that we had to relocate earlier on in the season. We will keep monitoring the success rate of other relocated nests.

In addition to our more regular visitors, the interesting sightings lately include:
- 68 Saunders’ Terns (Sterna saundersi) A
- 3 Pacific Golden Plovers (Pluvialis fulva) A
- 3 Bar-Tailed Godwits (Limosa lapponica) A
- 3 Common Snipes (Gallinago gallinago) V
- 1 Blue-Cheeked Bee-Eater (Merops persicus) V
- 1 Corncrake (Crex crex) V
- 1 Amur Falcon (Falco amurensis) V
- 1 Rosy Starling (Sturnus roseus) V
The most exciting of all was the Rosy Starling! This bird was spotted on the 31st January by guest Craig Nisbet. It is only the second record of such a bird on the island and there are only 5 previously accepted records of Rosy Starlings in the Seychelles by the Seychelles Bird Records Committee.

It’s Seagrass Awareness Month!
The importance of seagrass is often overlooked, with many failing to see the vital role it plays in helping to maintain a healthy marine eco-system. Seagrasses act as nurseries, providing food and shelter for juvenile fish, crustaceans and other marine life. They are a very important food source which is why you find so many turtles in the waters surrounding Bird Island. They support fisheries and also store carbon in their soils. Healthy seagrass meadows slow down water currents and reduce wave action, preventing erosion and building coastlines. We experienced a very strong storm surge in early December which brought an unusually large amount of seagrass and seaweed up onto the beaches. We are now in March and some remains on the East coast. The advantage of these wrack lines (washed up seaweed and seagrass) is that they provide the beach great natural protection from erosion. Normally, high spring tides will gradually clear the beaches of these wrack lines.
‘Blue carbon workshop – State of knowledge of seagrass habitats in Seychelles’
Conservation Officer Jo was invited by SeyCCAT to attend a two day workshop earlier this month, which focused on the current state of the knowledge of seagrass habitats in the Seychelles. It has been established that these habitats are of great importance to the Blue carbon economy and so there is an interest in mapping the seagrass beds in the archipelago. There is a possibility that Bird Island will get involved in the project. Stay tuned!May 12, 2020 4:03 pm
