Abstract
CACERES, Aimy and WILLIAMS DE CASTRO, Martha. Females' percentage of the bluehead macaw Primolius couloni (Sclater, 1876) kepts in captivity in four wildlife management centres in Peru. Ecol. apl. [online]. 2006, vol.5, n.1-2, pp.137-140. ISSN 1726-2216.
A total of 46 Primolius couloni individuals were studied in four different wildlife management centers in Peru: Huachipa Zoological Park, CIRES-Peru Breeding Center, Jean De Conick Breeding Center and Mundo Silvestre Breeding Center. The goal of this research was to determine the percentage of females of Primolius couloni kept in captivity with the objective of helping different wildlife management centers in developing future reproductive plans. The results show that 10.26% female Primolius couloni are kept in captivity. This mounts only to four females out of 39 successfully sexed individuals. The low amount of female Primolius couloni kept in captivity could be due to: high female stress susceptibility during capture and commercialization; males could be captured more often than females or to a lower amount of females than males in wildlife populations.
