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 activities should be performed close to the end of the nesting period for minimal disturbance of parents and nestlings. Our results also provide information to aid wildlife guards in protecting active nests from poachers when chicks are close to fledging.
我们研究了绯红金刚鹦鹉（Ara macao）在哥斯达黎加中太平洋保护区的六个活跃巢穴中的亲鸟定时探访情况。随着雏鸟长大，亲鸟在巢内的总时间显著减少。研究结果为科学家规划对雏鸟的侵入性活动（如佩戴无线电项圈或采集生物样本）提供了指导方针。这些活动应在育雏期接近尾声时进行，以尽量减少对亲鸟和雏鸟的干扰。我们的研究结果还为野生动物保护人员提供了信息，以帮助他们在雏鸟接近羽翼丰满时保护活跃的巢穴免受偷猎者的侵害。
