連生空包蛋黑天鵝疑同性戀
方瑞洋/新化報導

台南縣府經營的新化虎頭埤風景區，放養的黑天鵝連續兩年產下未受精蛋孵化失敗，園方人員束手無策，農委會畜試所彰化種畜繁殖場畜產科技系主任吳國欽昨表示，有一夫一妻配偶觀念的黑天鵝產下「空包蛋」的原因很多，同性戀行為也是其中之一。

兩年多前，新化虎頭埤風景區管理所為推動生態觀光，買了五對共十隻黑天鵝放養水中，為避免遭遊客侵犯攻擊，特選在湖中央最深處劃定水域輔謍峞A組成黑天鵝家族。

虎頭埤風景管理所花卉部主任蔡三安表示，十隻黑天鵝自動配成五對棲息水中，去年產下十多粒蛋，無論黑天鵝自行孵化或送人工孵化都失敗，期間黑天鵝遭偷抓或民眾惡作劇及意外死亡等共失去六隻，剩下的四隻又配成兩對形影不離，今年也產下十多粒蛋，再度送人工孵化都因未受精宣告繁殖失敗。

虎頭埤黑天鵝家族損兵折將又面臨絕後命運，園方人員對於黑天鵝正常成長，為何連年產下空包蛋，均不知所措。

畜試所彰化場主任吳國欽表示，黑天鵝產下未受精蛋的原因很多，包括天鵝發育不完全、營養太好太肥、棲地水池受到細菌感染、飼養環境不良、飼料成份不當等，此外，人為管理也會改變黑天鵝習性出現同性戀等常令人誤以為黑天鵝有交配行為，其實可能是兩隻母的同性戀，其雖配對交配，但再怎麼生蛋都是「空包蛋」。
