Growth data of Alaska SeaLife Center captive Steller's and spectacled eider ducklings in summers of 2015-2017

Data include Steller’s eider (Polysticta stelleri) and spectacled eider (Somateria fischeri) duckling growth data collected from birds reared at the Alaska SeaLife Center in Seward, Alaska during summers 2015-2017. Ducklings were weighed twice daily (09:00 and 21:00) during Days 1-14, daily (09:00) during Days 15-30, and every 3 days from Day 31-45 (Steller’s eiders) and 31-60 (spectacled eiders). Morphometric measurements (culmen, tarsus, 9th primary length) were taken every 3 days. Data are presented as two CSV files: 2016-2017_20SPEI_20mass_20morph_20data_March2018.csv 2015-2016_20STEI_20mass_20morph_20data_March2018.csv This dataset was generated as part of NPRB project 1518本数据集包含2015-2017年夏季，于阿拉斯加州苏厄德市阿拉斯加海洋生物中心（Alaska SeaLife Center）人工繁育的斯特勒氏绒鸭（Steller’s eider，Polysticta stelleri）与眼镜绒鸭（spectacled eider，Somateria fischeri）的雏鸟生长数据。 雏鸟的称重方案如下：1~14日龄每日两次（09:00与21:00），15~30日龄每日一次（09:00），31~45日龄（斯特勒氏绒鸭）及31~60日龄（眼镜绒鸭）则每3天称重一次。 形态学测量指标（喙长、跗跖长、第9枚初级飞羽长度）每3天采集一次。 本数据集以两个CSV文件形式存储：2016-2017 SPEI mass morph data March2018.csv、2015-2016 STEI mass morph data March2018.csv。 本数据集为NPRB项目1518的研究产出。
