Taxonomic note
Cibois et al. (2016) found that Procelsterna sits within Anous, which is accepted and results in P. cerulea changing name to Anous ceruleus (HBW and BirdLife International 2018). Procelsterna cerulea and P. albivitta (del Hoyo and Collar 2014) were previously lumped as P. cerulea following Sibley and Monroe (1990, 1993).

Population justification: The combined populations of Anous ceruleus and A. albivitta are estimated to number 27,000-120,000 individuals, but the total for A. cerulea is unknown.
Trend justification: The overall population trend is stable, although some populations have unknown trends (Delany and Scott 2006).
