- (a) Includes birds reported as Common Terns (illustrated on Plate 30 in Bradley and Norton 2009a).
- (b) Counts by R. Zambrano.
- (c) Widely scattered on small cays and rocky islets.
- (d) Shift sites frequently.
- (e) Upper limit includes birds reported as Common Terns.
- (f) Birds move between sites in the U.S. and British Virgin Is.; the total population was estimated as 2,500 pairs by Pierce (2009); this combined estimate was not taken into account in the totals listed by Bradley and Norton (2009b).
- (g) Count by Lowrie et al. (2012).
- Islands where nesting Roseate Terns have been reported in the past, but not in recent surveys: Hispaniola (Dominican Republic), Marie Galante, Los Roques (Venezuela), Curaçao, Bonaire. No recent surveys have been reported for the Bay Is., Honduras, where Roseate Terns nested in 1971, or from the Turneffe Is., Belize, where they were thought to be nesting in 1866. Unidentified terns were reported nesting in 1995 on Serrana Bank, Colombia (Bradley and Norton 2009a), where Roseate Terns had previously been seen in the breeding season (Nisbet 1980).
