Abstract:

In order to explore the influence of various environmental factors on the behavior of time distribution of Black-crowned Night Heron in spring, From March to April in 2016 year, we studied the acts of the Black-crowned Night Heron in the Xuanwu Lake, and adapted to the instantaneous scanning method to do the action sampling. The results showed that, Black-crowned Night Heron standing and the rest mainly in the main, and the two account for more than 60% in the whole action. But the actions, such as looking for food, flight and walk less than 10% all the time. The actions of cleaning up the feather are higher in proportion, about most between in 10%~30%.After calculating the actions on the earth and in the water area, indicate that the Duckling in the two habitats have different patterns of allocation of time. On the land, Black-crowned Night Heron standing is the main acts (about 41.56%), followed by the rest (about 33.55%), the actions of cleaning up in the third place, accounting for 15.86 %; the other actions such as feeding, walking and fighting was 2.64%, 6.38% and 3.46% respectively in the day.
