小燕鷗又名白額燕鷗,5至7月份過境台灣,屬於較少見的夏季候鳥,不少小燕鷗媽媽也會築巢、下蛋,孵化新的小燕鷗,苗栗縣自然生態學會理事長曹燕銘近來也發現苗栗海岸孵化小燕鷗喜訊,並與地方知名攝影師張麥斯前往記錄生態。

「牠們來這裡是繁殖後代,不是只有路過而已!」曹燕銘指出,目前苗栗海岸共有4個主要的小燕鷗繁殖場地,他每周會排定行程巡護統計,但曹燕銘發現,小燕鷗繁殖成功率相當低,以他家鄉通霄海域19巢僅1巢成功,鄰近的苑裡鎮海域19巢約6至7巢成功,竹南14巢則有6巢成功。

曹燕銘坦言,雖然下蛋的巢數不少,但實際成功率低,只能盡量避免人為影響,例如沙灘車碾壓沙灘時,若下方有小燕鷗巢穴與鳥蛋會造成小燕鷗和未孵化的生命死亡,他個人若發現沙灘車可能碾壓小燕鷗繁殖場地會前往勸說,天災無法控制,但人為的毀滅可以避免,畢竟小燕鷗每年在台灣僅有2、3個月的繁殖期。

曹燕銘也提及,設立告示牌等於是「告訴有心人這裡有保育類動物」,反而會吸引好奇民眾前往干擾或破壞,形成反效果,因此他發現的地點也不便公開。
