متن کاملScarlet Macaw (Ara macao) (Psitaciformes: Psittacidae) parental nest visitation in Costa Rica: implications for research and conservation.
We studied temporal parental visitation of Scarlet Macaws (Ara macao) to six active nests in the Central Pacific Conservation Region of Costa Rica. Total parental time in the nest decreased significantly as the nestlings aged. Results provide guidelines to scientists for planning invasive activities to nestlings, such as placement of radio collars, or biological sample collection. These activit...
متن کاملComparative analysis of microsatellite variability in five macaw species (Psittaciformes, Psittacidae): Application for conservation
Cross-amplification was tested and variability in microsatellite primers (designed for Neotropical parrots) compared, in five macaw species, viz., three endangered blue macaws (Cyanopsitta spixii [extinct in the wild], Anodorhynchus leari [endangered] and Anodorhynchus hyacinthinus [vulnerable]), and two unthreatened red macaws (Ara chloropterus and Ara macao). Among the primers tested, 84.6% s...

Even eight to ten millennia later, when the Spanish conquistadores arrived on the shores...
