On 22 July I was astounded to see a Swallowtail butterfly in a garden at Pointe au Sel. I am familiar with the other large butterflies in Seychelles, the resident Diadem and migrants African Monarch and Painted Lady, but this Swallowtail I had not seen in Seychelles before. My first assumption was that it must … More Another new addition to Seychelles’ fauna – another invasive alien species?
With an area of just under 20 km2, Silhouette is the third largest of Seychelles’ granitic islands. In terms of biodiversity it is one of the least disturbed islands in the archipelago, its rugged and heavily forested mountains having spared it from significant human occupation. Its fauna and flora encompass a high degree of endemism … More Myna problems on Silhouette Island, Seychelles
In my early blog posts (14 January 2016 and 16 May 2016) I described the then recent arrival in Seychelles of a small moth (Euproctis species) whose hairy caterpillar (in Creole senir plim) was defoliating trees and bushes, and whose hairs could cause intense irritation to the skin of humans and domestic pets. Having fed … More Return of Seychelles’ spiders?
11.6 km2 Assumption Island lies about 1100 km south-west of Mahe, Seychelles’ largest and most populous island, and is close to Aldabra atoll, famed for its relatively undisturbed ecosystem that qualified it for World Heritage Site status. Assumption is a raised coral island and was formerly home to a vast number of seabirds, especially boobies, … More Assumption Island – a miserable past, an uncertain future
Native to Africa, Egyptian Geese were introduced into Europe as decorative additions to wildfowl collections, both private and in urban parks, and also as zoo animals. In the UK, Janet Kear (Man and Wildfowl, Poyser 1990) reported that they were introduced in the 17th century, being part of the menagerie in St James’s Park in … More Egyptian Goose added to the European Union list of Invasive Alien Species of concern
Common Mynas Acrodotheres tristis like eggs. They have been recorded eating the eggs of many species, large sad small. In the process, they can endanger the survival of some of the world’s most endangered island endemic birds. Seabird eggs are often large and thus offer introduced Mynas a substantial meal. In 2015 Christine and I, … More Mynas can express their annoyance too
Earlier posts have described progress in the myna eradication project on North Island, Seychelles. The eradication has been proceeding well and is approaching its final stages. Green Islands Foundation, who are administering the project, are now advertising for a new volunteer (https://greenislandsfoundation.blogspot.co.uk/p/blog-page_29.html) to assist with the completion of the eradication. The full advertisement is printed … More The North Island myna eradication – update January 2017
On 12 October 2016 Christine and I drove to a complex of reservoirs to the west of Antequera. In my experience these reservoirs in Spain normally attract few birds apart from gulls and the occasional Cormorant. On this occasion, however, one of the reservoirs, Embalse de Guadalhorce, held flocks of Coot and Pochards that are … More Egyptian Geese in Andalucía
The project aimed at eradication Common Mynas from North Island, Seychelles, funded by North Island and overseen by Green Islands Foundation (see blog posts of 21 May, 8 June, 11 August and 7 September) continues. Maxine Little and Jeremy Waters, the current volunteers, began work on 5 August, with Christine and me training them in … More North Island myna eradication update
“Invasive alien species” (IAS) is the term used to describe animal and plant (and even bacteria, viruses) species that have been deliberately or accidentally introduced to new parts of the world, generally through human a gency, and having been introduced they have the capacity to thrive in their new environments. In so doing they can … More Invasive Alien Species (IAS) – not just on small islands
