Survival of radio-collared nestling Puerto Rican Parrots

Abstract

Remnant population of the critically endangered Puerto Rican Parrot (Amazona vittata) survives in the Luquillo Mountains of northeastern Puerto Rico (Snyder et al. 1987). During the last three decades, intensive research and management have reversed a precipitous population decline to one of continual population growth (Wiley 1980, Snyder et al. 1987, Lindsey et al. 1989, Lindsey 1992). Prior to Hurricane Hugo in 1989, the wild population had grown from 14 birds during the mid-1970s to 47 (Meyers 1995). The hurricane reduced the population to about 22-24 birds; however, by early 1994, the population was estimated at 38-39 individuals (Meyers 1995). Population surveys for late 1994 (post-breeding) and early 1995 were 42 and 33, respectively (E J. Vilella and E Ndfiez, pers. comm.).
