Study on the Winter Food of Hazel Grouse Cao Yuekun Biology Department, Fushun Normal Collage

本文报道了花尾榛鸡冬季食性研究的情况，发现在冬季稳定期（１２月至１月）取食地和食性都有变化．取食地主要是次生阔叶林，而取食的树种简单，仅取食桦树、榛树和杨树．但以桦树为最喜树种，取食部位较宽，为叶、芽苞和花序及嫩枝，对榛树取食叶和花序，对杨树仅食芽苞．

The assay gives the readers a description about eating habit of hazel grouse in winter. The researchers found that their eating place and habits are changeable during winters stable period (December to January). Eating place is mainly in secondary broad-leaf woods, simply choosing birch, hazel and poplar, but birch is the most favorable one. The eating parts are wide, from leaves, buds, inflorescence to young shoots, yet to hazel only lesves and inflorescence, to poplar simply buds. The eating size assumes curve regression with the size of mouth.
