之前貼過用Sony RX10 M4拍的黑喉鴝,本篇為同時間用D7200拍的,等效焦長差不多,看看感光元件大小與畫質的關係吧(當然鏡頭素質也有影響,不過兩邊的鏡頭素質應該差異不大)。

黑喉鴝公鳥的冬羽與夏羽是天差地遠,夏羽黑、白對比明顯再加上紅褐色的胸口,十分漂亮,台灣在春過境時,偶爾能見到公鳥繁殖羽的風采,只可惜春過境待的時間都很短暫,少部分個體會在台灣度冬,所以冬羽個體相對容易見到。

此羽在大園沙崙待了一陣子,接受鳥友的招待變得相當穩定,有將近一個月的時間,也去紀錄了幾次,這次試用Sony RX 10M4,很輕便好用。

大園的鶺鴒.Wagtails@Dayuan.2018

White_Wagtail_SONY_00118

鶺鴒在台灣的冬季是很容易見到的候鳥(白鶺鴒有繁殖紀錄但很少),各種鶺鴒的習性十分相近,尾羽長,飛行路線宛如波浪形,喜於水域旁的地面活動覓食,尾羽上下擺動。常見的有白鶺鴒、灰鶺鴒與黃鶺鴒(每一種鶺鴒各又區分出不同亞種,個人拍攝太少,尚無法介紹至亞種),白鶺鴒為白灰色系相對好認,黃鶺鴒與灰鶺鴒則同是黃色系,辨識上就比較需要去用心比較相對應的特徵,黃鶺鴒的黃是較濃的鵝黃色,腳黑色,灰鶺鴒的黃是粉黃色,腳呈紅黃色至淺棕色,冬羽時黃鶺鴒至甚黃色部分會較少,所以常有很多朋友認錯,看腳的顏色比較不會出錯。

三坑棕三趾鶉.Barred Buttonquail paired@Taoyuan.2018/06/18

Barred_Buttonquail_5059

龍潭三坑地區是我經常去紀錄棕三趾鶉的地方,往年有Happy兄乎是每日地照顧而十分穩定,但2018下半年Happy不常去了,棕三趾鶉變得十分難等,只能偶爾巧遇看著牠們鑽入草叢……

另找一個隱蔽的角落車拍,有竹雞番鵑黑頭文鳥等,終於棕三趾鶉也從遠方走了過來,不過這個點鳥況很不穩定,拍不到什麼很正常,後來也漸獑少去了。

三坑黃頭扇尾鶯(雌).Golden-headed Cisticola@Taoyuan.2018/06/03

Golden-headed_Cisticola_2112

黃頭扇尾鶯棕扇尾鶯的雄鳥繁殖羽有明顯的不同,鳴聲差異也很大,可是其母鳥及公鳥非繁殖羽卻極為相似(黃頭扇尾鶯冬羽供參),區別點就在眉線的明顯與否,棕扇尾鶯的白眉線相當明顯。

此羽白眉線不明顯,是黃頭扇尾鶯,因為是在六月繁殖季拍到的,所以是母鳥,個人很少見到黃頭扇尾鶯的母鳥,大概是因為放鳥音時,只有公鳥會出來對嗆……
