2500 - 100,000 individuals
Comments: World population in the late 1980s was 3000-5000 breeding pairs, with about 2000 of these in the U.S., and with 3/4 of the U.S. breeding population occurring in Texas (Spendelow and Patton 1988). In the U.S., most abundant in winter along the Texas coast and in southern Florida (Root 1988). Relative abundance (birds per 100 survey hours) on Christmas Bird Count for 1959-1988 was 0.39 in Florida, 3.29 in Texas, and 1.48 survey-wide (Sauer et al. 1996).
