St Helena 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. October to early December tends to be the best period for accidentals.
A European White Stork Ciconia ciconia was photographed at Sisters Walk, on 2 October 2007; this species is a very rare accidental visitor to the island.
Sightings during the period 1998 to 2002 include Cattle Egret Bubulcus ibis, Grey Heron Ardea cinerea, White Stork Ciconia ciconia, Allen’s Gallinule Porphyrio alleni, Sanderling Calidris alba, Red Knot C. canutus and White-rumped Sandpiper C. fuscicollis.
Star rarities during the past 20 years include Murphy’s Petrel Pterodroma ultima, Purple Swamphen Porphyrio porphyrio and Amur Falcon Falco amurensis.
