林夜鹰、黄冠啄木鸟、雪雁在浙江的发现记述

New Distribution Record of Caprimulgus affinis, Picus chlorolophus and Anser caerulescens in Zhejiang Province

摘要: 本文记述了2022—2023年3种浙江省鸟类分布新记录，分别是林夜鹰Caprimulgus affinis、黄冠啄木鸟Picus chlorolophus和雪雁Anser caerulescens，其中，林夜鹰和黄冠啄木鸟可能为气候变暖等因素导致的分布北扩，雪雁可能是因为北方冬季极寒天气和食物匮乏或在迁徙途中脱离队伍等南下；从居留型看，推测林夜鹰在浙江的居留型应为留鸟或夏候鸟，黄冠啄木鸟在浙江的居留型应为留鸟，雪雁在浙江应为迷鸟。本次的发现结果是对浙江鸟类多样性数据资料的进一步补充。
