Abstract

Fifteen juvenile Puerto Rican Parrots (Amazona vittata) from wild nests in 1985, 1986 and 1987 were radio monitored an average of 110 +_ 15.9 (SE) d (range 4-209 d) post-fiedging.. Minimum survival was 67% (n = 3) in 1985, 100%( n = 4) in 1986 and 43% (n = 7) in 1987. Most mortality (three of five deaths) occurred during the first 35 d following fledging. A major cause of mortality was predation by raptors. This research shows that additional studies are needed to define mortality causes to juvenile and adult free-flying Puerto Rican Parrots and to develop management guidelines to increase survival.
