| 摘 要： | 对崇明东滩白头鹤（Grus monacha)的越冬生态进行了研究。白头鹤在崇明东滩越冬期140－150d。越冬期主要食物为海三棱Biao草（Scirpus mariqueter)的地下球茎，海三棱Biao草和Biao草（S.triqueter)的根茎。受气候和季节的影响，越冬后期比前期的日活动时间增加1h。潮汐节律影响越冬白头鹤行为活动的时间分配，觅食地的选择以及集群大小。滩涂的快速围垦和滩涂植被的演替对白头鹤的越冬栖息地造成严重的影响。

Wintering Ecology of the Hooded Crane in the Eastern Tideland of Chongming Island |
| |
| Abstract: | Wintering ecology of the hooded crane (Grus monacha) in the Eastern Tideland of Chongming Island was studied. Hooded cranes stayed in the Eastern Tideland of Chongming Island for 140-150 days. During this period hooded cranes fed mainly on corms of Scirpus mariqueter and rhizomes of S.mariqueter and S.triqueter. Effected by season and weather conditions, the time spent on diurnal activities in the later wintering stage was about one hour longer than in the early wintering stage. Tide rhythm had strong influence on the time budget and flocking behavior of hooded cranes. The loss of natural wetlands caused by rapid land reclamation is a serious threat to hooded cranes and their habitats in the Eastern Tideland of Chongming Island. |
