Method Primary source abstract: "[Investigators] review the conservation status of, and threats to, all 346 species of seabirds, based on BirdLife International’s data and assessments for the 2010 IUCN Red List."
Comments P.1770 left column bottom paragraph: "Seabirds are excellent candidates for sensory‐based conservation because they employ a range of sensory modes, display complex behaviours and cognition (Schreiber & Burger, 2001), and are often highly threatened (Croxall et al., 2012, IUCN, 2014, Paleczny et al., 2015). Seabirds have experienced steep recent population declines – 28% of the ∼347 seabird species are globally threatened and 5% are critically endangered (primary source)."
