摘　　要：2004年2月11日～6月10日,用直接观察法中的随机取样法和扫描取样法,对四川南充市及郊区(北纬30°41′～ 30°51′, 东经106°01′～106°07′)白头鹎的食性和取食空间生态位进行了研究.结果显示:白头鹎为杂食性鸟类,主要在乔木树冠、灌丛、菜地、草地和空中取食约30种植物的芽、嫩叶、花、花蜜、果实及昆虫.在育雏以前以植物性食物为主,动物性食物的频次仅占食物总频次的1.77%.育雏时,其捕食动物性食物的频次占食物总频次的55%.From February to June, 2004, the feeding and spatial niche of Pycnonotus sinensis were studied in Nanchong City and outskirts （30°41′- 30°51′N, 106°01′-106°07′E） by taking a random sample or scanning. The results showed that Pycnonotus sinensis was omnivorous bird and mostly fed on eating bud, tender leaf, flower, nectar, fruit and Lepidoptera insects in crown of arbor, shrub, vegetable plot, grassland and sky. Before brood, it ate mainly plant food and the rate of animal food was only 1.77 %, yet the rate of animal food reached 55 % during brood.
