100,000 - 1,000,000 individuals
Comments: Total adult population size is unknown but apparently exceeds 100,000. Bancroft and Bownman (2001) and Rich et al. (2004) reported population size as 15,000 in the United States (Florida). Population estimates for other regions are relatively old. Blankenship (1977) reported that the Bahamas may have as many as 30,000 pairs. Arendt et al. (1979) estimated that theDominican Republic may have 5,000-10,000 pairs. In the mid-1970s in Puerto Rico, the estimated breeding population was 6,000 on Isla Mona, about 4,000 on Puerto Rico proper, 300 on Isla Culebra, and 400 on Isla Vieques (Wiley 1979). The largest nesting population is probably in Cuba (Bancroft and Bowman 2001).
Birdflife International (2008) reported the global number of mature individuals as 550,000 and cited the Partners in Flight: North American Landbird Conservation Plan (Rich et al. 2004) as the justification, but that document deals only with the United States and Canada and does not provide population estimates for other regions.
