摘要

2016年8月至2017年3月,在孟加拉国Jahangirnagar大学校园研究了板栗尾椋鸟的食物和摄食行为。共观察了414次,结果表明,它们是杂食性的,动物性饲料占67.15%,植物性饲料占20.53%。它们主要以昆虫幼虫为食(39%),其次是甲虫(16%)、花蜜(14%)、食物垃圾(12%)、水果(7%)、蜻蜓(7%)、豆妈咪(3%)和蠕虫(2%)。在5种摄食方式中,板栗八哥的主要摄食方式是悬挂(37.92%),其次是啄食(6.76%)。利用最多的取食植物是雨树(33.76%),其次是白翅草(30.55%),板尾椋鸟最喜欢的栖息高度为6 ~ 9m(44.9%),其次是3 ~ 6m(31.6%)。贾汉吉纳格尔大学;科学通报8(1):17-23,2019 (6)

Food and feeding behaviour of Chestnut-tailed Starling, Sturnia malabarica at Jahangirnagar University Campus, Bangladesh
Food and feeding behaviour of Chestnut-tailed Starling, Sturnia malabarica were studied at Jahangirnagar University Campus, Bangladesh, from August 2016 to March 2017. A total of 414 observations were made on the feeding maneuver and it was noted that they were omnivorous consuming 67.15% animal diet compared to 20.53%plant diet.They predominantly consumedinsect larvae(39%) followed by beetles (16%), nectar (14%), food wastes (12%), fruits (7%), dragonflies (7%), damselflies (3%), and worms (2%).Among the five types of feeding modes recorded,hang-upmode (37.92%) was major feeding technique in Chestnuttailed Starling while pecking mode (6.76%)was least used. Rain tree (Samanea saman) (33.76%) followed by White siris (Albizia procera) (30.55%) was recorded as the most utilized foraging plant while mostly preferred perching height by Chestnut-tailed Starling was 6-9m (44.9%) followed by 3-6m (31.6%).
