摘　　要：彩鹬Rostratulabenghalensis是一类中小型涉禽，主要分布于我国华北东部、西南和沿海地区，是江西吉安地区常见留鸟。为了解当地彩鹬的繁殖生态，我们于2011—2012年对其繁殖进行了调查研究。结果表明，彩鹬3月中旬开始营巢，巢为典型的水面浮巢，平均巢外径为161．62mm，巢内径为108．61mm，巢深为39．14mm；3月下旬至4月中旬产卵，窝卵数为3．46（2-4），平均卵重为11．76g，卯大小为36．35mm×25．41mm。彩鹬雄鸟承担大部分营巢和孵卵工作，孵卵期18—19d。雏鸟为早成鸟，出壳后不久便能在水中活动，随亲鸟离开巢区。Painted snipe （Rostratula benghalensis） is a kind of small waders mainly distributed in the east of north China, southwest and coastal area of China, and also a resident bird in Ji＇an, Jiangxi Province. The breeding ecology of painted snipe was investigated from 2011 to 2012. The result showed that the nesting of painted snipe was from middle March, and the nest was typical water floating. The parameter of the nest was 161.62 mm× 108.61 mm× 39.14 mm. Painted snipe laid eggs from late March to middle April, and the clutch size was 3.46 （2 - 4）. The average weight of the eggs was 11.76 g, and the average size was 36.35 mm × 25. 41 mm. The male bird undertook the most work in nesting and incubating which u- sually lasted for 18 - 19 days. The fledgling were precocious and able to swim after hatching, and they would leave the nest following the parent birds.
