尾下覆羽 的英文怎麼說
中文拼音 [wěixiàfùyǔ]
尾下覆羽
英文
lower tall coverts-
Dark - centred undertail coverts = dark - sided flycatcher ( white in grey - streaked )
暗色為中心的尾下覆羽=鮮卑? (烏? ) (灰斑?的是白色的)As you cannot see the rumps of any of these birds and the undertail coverts lack salmon tones i would be reluctant to call them lesser cuckoos
由於在圖片中無法看到這幾只鳥的腰部而且尾下覆羽不帶橘紅色味,個人對稱?們為小杜鵑有所保留。
