Winter is upon us and a flock of winter migratory birds has again stopped over on Penghu Island. On Nov. 1, six large ducks appeared at the Penghu Chenggong Reservoir and flocked on the water for a leisurely swim and to hunt for food. A bird watcher, surnamed Lee, who discovered the birds, informed the Wild Bird Society of Penghu, who verified the birds as rare migratory “bean geese.” Because bean geese are naturally wary, the society has called upon the public not to disturb their ecological environment and to admire the birds from a distance.

According to the literature, bean geese are classified as a rare winter migratory bird. The male and female are identical in appearance, and they are naturally wary and predisposed to living in wide-open spaces. They remain alert with their necks outstretched while feeding on grass and seedlings and emit a dull honking sound.

Although bean geese are a type of large duck, they differ from normal geese in that they are innately wary and become agitated easily. If their resting environment is not large enough, they will not dare to linger; therefore they are rarely seen in Penghu and Taiwan in general. It is thought that the birds have appeared in Penghu Chenggong Reservoir this time due to the high level of rainfall this year. With the reservoir’s water level full-to-brimming, the surface area of the lake is comparatively large, which also makes it easy for the birds to hunt for food. This is why the bean geese chose the reservoir as their temporary stopover point, which has provided a feast for the eyes of bird watchers.

根據文獻記載,「寒林豆雁」屬稀有冬候鳥,雌雄同型,生性機警,以家族型態生活在開闊陸域環境,連覓食草類、秧苗時都會引頸警戒,還會發出深沉的喇叭聲。

雖然寒林豆雁是大型鴨子,跟一般看到的鵝一樣大,但因為生性機警,易受驚擾,所以如果棲息環境範圍不夠大,不太敢停下來,因此較少出現在台灣和澎湖,此次現身澎湖成功水庫,猜測與今年雨量豐沛,成功水庫儲水滿水位,因此湖面相當廣闊,同時容易覓食,才會選擇在成功水庫做為短暫休息點,讓鳥友們大飽眼福。
