Global Short Term Trend: Decline of 10-70%
Comments: Range-wide trends are poorly documented, but in most of the range this species undoubtedly has declined in population size over the past three generations (three generations is at least 45 years and may be as high as 60-75 years).
In Florida, extent of occurrence, area of occupancy, population size, nesting range, and number of known nests have been increasing in recent decades (Mazzoti et al. 2007, USFWS 2007). The maximum number of nesting females in Florida increased from 20 in 1975 to 85 in 2004 (Mazzoti et al. 2007).
See Schwartz and Henderson (1991) and Thorbjarnarson (1988) for information on status in Haiti.
Global Long Term Trend: Decline of 10-90%
Comments: Area of occupancy, number of subpopulations, and especially population size have undergone a major long-term decline, but the degree of decline is uncertain.
