A vagrant Franklin’s Gull Larus pipixcan in breeding plumage was observed on 14 April 2011.
In 2009, on Tristan, up to four Cattle Egrets Bubulcus ibis were noted: one on 3 April, 2–3 from 10 May, 3–4 from 3 June, with one still present on 27 June. One was also on Nightingale from 6 April to 10 June at least. An immature Little Blue Heron Egretta caerulea was on Tristan from 16 April, with a second there from 24 April; one was still present on 22 May. Possibly the first Little Egret E. garzetta for Tristan da Cunha stayed on the island on 3–27 April. A Snowy Egret E. thula was present from 16 April to 3 June. Thus, on 16 April, there were four white herons on the pool by the volcano: a Cattle Egret, a Little Blue Heron, a Little Egret and a Snowy Egret. Other vagrants included an immature American Purple Gallinule Porphyrio martinica on 18–22 April at least, with another on 1 June, a Hudsonian Whimbrel Numenius phaeopus hudsonicus at the Patches on 2–4 January at least, and a Franklin’s Gull Larus pipixcan on 19 April. An adult Purple Heron Ardea purpurea flew past a ship west of Gough Island, in the South Atlantic, at 40°25’91”S 09°59’53”W, heading towards South America on 8 April 2009; this constitutes the first record for the Tristan da Cunha group.
