湖北兴山红嘴相思鸟繁殖生态初报

2005年4月～2007年8月,在湖北省兴山县龙门河地区,对红嘴相思鸟(Leiothrix lutea)的繁殖生态进行了初步研究。研究结果显示,红嘴相思鸟在此地区的繁殖时间为4月中旬至7月下旬。巢多营于山坡上、山谷中的乔木林、灌木林遮蔽下的箬竹(Indocalamus wilsoni)和小灌木上,也营巢于农田边、山间小路旁、林间空地的箬竹丛或灌丛中。巢材主要有细树枝、细树根、细藤、箬竹叶、茅草叶、细草茎、青苔等。雌雄鸟共同筑巢,筑巢过程较为迅速,一般5～7d即可完成。雌鸟每天产一枚卵,产卵时间一般在清晨。窝卵数3.41±0.80(n=61)。孵卵期11～13d(n=6)。雏鸟晚成性,雌雄共同育雏,育雏期9～10d。雏鸟发育十分迅速,但离巢时身体发育尚未完善。红嘴相思鸟在此地区的繁殖成功率约为22.95%(n=61)。

The Preliminary Study on Breeding Habit of Leiothrix lutea at Xingshan County,Hubei

Breeding habit of Red-billed Leiothrix ( Leiothrix lutea) was preliminarily studied at Longmenhe Village of Xingshan County,Hubei from April,2005 to August,2007. L. lutea reproduce during the middle ten days of April to the last ten days of July in Longmenhe area. The birds built their nests on the Dwarf Bamboo (Indocalamus wilsoni) or short shrub shaded by arbor or shrubbery on slope or near the farmland and footpath. The building materials include withe,slender root,bine,dwarf bamboo leaves,grass leaves and stems,and lichen and so on. The process of building nest last 5 to 7 days and both male and female were involved in. Female lay an egg in early morning everyday. The mean clutch size is 3. 41 ± 0. 80 ( n = 61) . The altricial nestlings hatched after 11-13 d (n = 6) incubation. The parent fed their offspring for 9 or 10 days before they left nests when they have not full-developed yet. The breeding successful rate is about 22. 95% ( n = 61) in the study area.
