2007年10至2008年3月，笔者利用定点观测法对半边湖的鸟类资源再次进行了监测。调查到国家一级保护鸟类2种：东方白鹳和白鹤；国家二级保护鸟类三种：小天鹅、灰鹤、普通狂；其它鸟类6种，共计11种956只。对比2006年10月至2007年2月的调查结果发现：三峡大量蓄洪、滥种速生杨、滥捕鱼虾等因素是半边湖珍稀鸟类减少的主要原因。

From October 2007 to March 2008, the author had monitored bird resources in Half Lake using fixed-point observation again. The investigation shows that there are 11 sorts of birds for the total of 956 live in the lake region, among them are two national level protection Birds ： Oriental white stork and white crane; three national secondary protection birds： little swan, crane, general mad; the other six kinds of birds. Contrast to the invostigation from October 2006 to February 2007, the author finds that the main causes of the birds reducing in Half Lake region lie in the following facts： a large number of flood storage in the Three Gorges, the over-fast growing species, fish and shrimp fishing.
