英语听力：Wild China 美丽中国：彩云之南-5（在线收听） |
On the far side of the great Nujiang gorge, the plant hunters made a remarkable discovery. Far from the tropics, they seemed to be entering a steamy, vibrant tropical jungle--the forest of Gaoligongshan. The flora here is unlike anywhere else in the world. Next to subtropical species, alpine plants grow in giant form. Crowning the canopy, rhododendrons up to 30 meters high. In April and May, their flowers turn the forests ruby red, attracting bird species found only here. Constant moisture in the air means that the branches are laden with flowering epiphytes, fiercely guarded by tiny sunbirds unique to these valleys. Nectar feeders, these are the hummingbirds of the old world tropics.
The forests of Gaoligongshan are home to some of China's rarest wildlife. This is a female Temminck's Tragopan. She has a colorful male admirer. He's hoping to woo her with his peculiar peekaboo display, but she's not about to be rushed. His colorful skin wattle reflects more light than feathers do. To her, this is like a neon sign. Seeing his chance, the male makes his move.
Constant moisture in the Gaoligongshan forest means that throughout the year, there are always fruits on the trees. Such abundance of food encourages a high diversity of fruit eaters more commonly found in the tropics. The black giant squirrel is found only in undisturbed rainforest. At close to a meter in length, it's one of the world's largest squirrels. |
