摘　　要：2011—2013年4—10月．在山西芦芽山国家级自然保护区对虎纹伯劳的生态习性进行了观察。结果表明：虎纹伯劳在该区为夏候鸟，最早4月23日迁来．最晚9月27日迁走，居留期为147～155d。迁来初期，虎纹伯劳常在低山灌丛带、河谷地带的向阳处或电线、电杆活动。进入繁殖期。虎纹伯劳多转移向中海拔地区的疏林灌丛带。虎纹伯劳在该区的种群密度在8、9月最大，每千米遇见只数分别为0．51、O．58只；在4、6月种群密度最小。每千米遇见只数0．18只，3年在该区的种群密度平均为0．29只／km2繁殖前（5月）每千米遇见只数为O-33只，繁殖后（9月）每千米遇见只数0．58只，繁殖后比繁殖前每千米遇见只数增长76％。繁殖期5月下旬至7月中旬，5月上旬营巢，雌雄鸟共同营巢，营巢期7～8d，窝卵数4～6枚，孵卵由雌鸟承担，孵化期15～16d，雏鸟晚成性，巢内育雏14～16d，平均孵化率为89．7％，平均成活率为89．2％．繁殖力2.2只，食物主要以昆虫为主，占食物种类的98％以上。Lanius tigrinus＇s ecological habit was studied from April to Qctober in the year between 2011 and 2013 in Shanxi Luya Mountain Nature Reserve.The results showed that Lanius tigrinus was a summer bird in this area,it moved to this area on April 23 and returned on September 27 and stayed here about 147--155 d. At the beginning of migrate ,Lanius tigrinus often lived in low mountain shrubland river valley with a sunny exposure or wire pole.Lanius tigrinus moved to the woodlands shrubland of middle elevation area during the breeding season. Population density of Lanius tigrinus in the area was the greatest in August and September,every kilometer meet number was 0.51 and 0.58 respectively;Population density of Lanius tigrinus in the area reached the least in April and June, every kilometer meet number was O. 18, average population density of this area was 0.29 per kilomenter during the three years. Before breeding every kilometer meet number was 0.33 in May ,after breeding every kilometer meet number was 0.58 in September, every kiolmeter meet number incresased by 76% than before breeding. Breeding period from late May to mid July ,Lanius tigrinus started nesting generally in early May. Male and female bird nested together, nesting period was 7-8 d, clutch size was 4-6 pieces, eggs was borned by the female,the incubation period was 15-16 d,Nestlings grew to maturity late,The nest brood period was 14-16 days,average hatching rate was 89.7%, average survival rate was 89.2%, the fecundity was 2.2,insects played an important role in what Lanius tigrinus eated, accounting for over 98% of the food species
