from ABC previous Bulletins

A field trip to Ascension on 7–20 February 2008 coincided with the Common Myna Acridotheres tristis breeding season. Since their introduction in 1879 mynas have adapted to the barren island and to shortages of invertebrates and fruit, and the lack of nest holes in trees and buildings. In addition to scavenging deserted eggs, they predated many hundreds of eggs of Sooty Terns Sterna fuscata. At the rubbish dump mynas were nesting communally and more than 20 nests, two containing chicks close to fledging, were discovered at the end of c.70 cm- long tunnels excavated (presumably by the mynas themselves) c.20 cm below a shallow lava crust. The ability to adapt to harsh conditions makes this aggressive species a serious threat to the island’s native avifauna.

In 2007, Masked Boobies Sula dactylatra successfully re-colonised the main island; this was facilitated by the recent successful feral cat eradication programme. On 3 May, 186 pairs were incubating eggs on ‘Letterbox’ peninsula, on the remote eastern side. On 22 May, a second expedition from the Army Ornithological Society found 151 apparently occupied nests. Twelve pairs had successfully hatched a chick, one nest contained a predated egg and in another nest the egg was missing (both predated by rats). An Ascension Frigatebird Fregata aquila was found dead at Waterside on 21 May, entangled in nylon fishing line and a fish hook through the lower mandible. A European Turtle Dove Streptopelia turtur was seen at Travellers on 17 May; this is a new vagrant to the island.

Ascension Island is so far off the main migration routes that vagrants are very scarce. The island is, however, very much under-watched and much is undoubtedly missed. A full list of vagrants up to 2002 is given below and see also (Bourne & Simmons 1998).
