【Abstract】 From April to May 2000, the behavior of 4 pairs of wild red-crowned cranes in breeding season was studied by objective sampling and all-events sampling in Zhalong National Natural Reserve. The results indicate that the behavior of red-crowned cranes can be divided into 6 types, namely, feeding, resting, guarding, walking-around, pluming and breeding (including wooing, mating, nidificating, laying egg, hatching, nestling nursing). Red-crowned crane sets up territory for ensuring the success of breeding. The behavior changes in different phase in breeding season. Feeding is the most frequent behavior before laying eggs, while the frequency of breeding reaches to the highest as the decrease of the resting and increase of guarding during egg-hatching phase.更多还原
