In early winter, the gray-faced buzzard-hawk passes through on its way south from Japan. When a cold front rolls through and the temperature plummets, birds that are usually resident at higher elevations, such as the green-backed tit and the Taiwan yuhina, move down to the lower elevations to avoid the cold, and the colors on the dead acacia change once again.
秋冬之際，從日本一路南下的灰面鷲路過此地；寒流來襲，氣溫驟降，青背山雀、冠羽畫眉等高海拔鳥兒下山避寒，相思樹上又將是另一番景色了。
