Abstract

Knowledge of nesting behaviors of tropical birds, even for the magnificent Resplendent Quetzal, comes from few records of observations outside the nest. However, the popularity of the bird in the Monteverde Cloud Forest Preserve inspired the Tropical Science Center to place a camera inside one of the box nests just before the 2000 nesting season. I studied the images taken during the entire nesting period. Upon analysis of the data, I found that parental care and behavior changed significantly as the chick aged. Additionally, only females slept in the nest, and although both the male and female brooded and attended to the young, the female spent significantly more time in the nest than the male (p < 0.05). As the chick aged, the time that the parents spent in the nest decreased significantly (p < 0.0001). Observations recorded by others from outside the nest concur with this data. Nest predation is high in tropical environments; thus, having both parents alternating care in the nest may increase the chances of a successful brood. However, in my study of the quetzal, the duties were not necessarily equally shared, leaving the female more vulnerable to predation. Existen pocos registros sobre el período de anidación para los quetzales y las observaciones son del exterior del nido. Pero la popularidad de los quetzales en el Bosque Nuboso Monteverde causo que el Centro Científico Tropical pusiera una cámara en el nido después del periodo 2000 de anidación. Yo estudie las fotos que se tomaron durante el periodo entero de anidación. Después del análisis, yo encontré que los padres no estuvieron en la madriguera mucho como el pollito, también que solamente la madre dormía en el nido. Aunque los dos padres empollaron y atendieron al pollito, la madre pasaba más tiempo en la madriguera que el padre (p < 0.05). El tiempo que los padres pasaron en el nido disminuyo significativamente conforme el pollito creció (p < 0.0001). Observaciones del exterior de la madriguera concuerda con los datos. EI riesgo de predación está en el crecimiento en los trópicos. Entonces teniendo los dos padres se puede aumentar la probabilidad de tener una nidada exitosa. Pero en esta investigación del quetzal las obligaciones entre los padres no fueron equivalentes.
