Introduction

The Tristan da Cunha archipelago comprises three main islands: Tristan, Inaccessible and Nightingale at 37ºS 12ºW, with Gough Island (40ºS 10ºW) the only other temperate oceanic island in the South Atlantic Ocean (Ryan 2007). Tristan and Gough are important breeding sites for 25 species of seabirds (Ryan 2008; Ryan et al. 2014; 2015; Robertson et al. 2016), and a further 30 species of non-breeding seabirds have been reported from the islands (Ryan 2007; Visser et al. 2009; Ryan 2010). We report three additional species from the islands based on observations from 2017 to 2019.
