Protein and sucrose intake by captive hummingbirds

This database shows the amount of protein and sucrose ingested by two captive hummingbird species (Cynanthus latirrostris and Saucerottia beryllina). We obtained intake data for both species by conducting free-choice feeding trials. We offered hummingbirds two diets varying in protein (0.2%-2%) and sucrose (5%-30%) concentrations. Experimental trials lasted 13 days. Intake data (grams of protein and sucrose consumed per day) are reported both without body mass adjustments and divided by the metabolic body mass of the individuals (mbm = g0.75).

本数据库记录了两种人工圈养蜂鸟物种（Cynanthus latirrostris和Saucerottia beryllina）的蛋白质与蔗糖摄入量。本研究通过自由选择采食试验获取了这两个物种的摄食数据。实验为受试蜂鸟提供了两种日粮，其蛋白质浓度范围为0.2%~2%，蔗糖浓度范围为5%~30%。单次试验持续时长为13天。本研究报告了两类摄食数据：一是未经体重校正的每日蛋白质与蔗糖摄食量（单位：克）；二是经个体代谢体重（metabolic body mass，mbm = g^0.75）校正后的摄食量。
