greater coverts meaning in English
大覆羽
Examples
- First warbler yellow - browed , the dark bases to the secondaries and black - centred greater coverts leave few other options
第一只是黄眉柳莺,次级飞羽暗色的基部及以黑色为中心的大覆羽留下的选择很少 - It is a very big generalization , and some species are exceptions , but generally first summer individuals can only be separated by retained juvenile remiges and rectrices or by moult limits in the greater coverts
这是一个很概括的看法,且某些鸟种是例外,但一般而言一龄夏羽个体只能以还留著的幼鸟飞羽和尾羽,或大覆羽的换羽界限来区分
