Research On Reproductive Behavior And Space Utilization In Captive Hooded Crane (Grus Monacha)

This study start at April to September in 2014 and April to June in 2015, This study sites located in Changchun Zoological Park. Select paired for many years and good breeding adult Hooded Crane (Grus monacha),Observe the entire pre-breeding period to finalize hooded crane behavior observed spectra and determine the scanning method,Instantaneous scanning method for ordinary behavior, including feeding, walking, caring, standing, resting, reproducting records were observed,using timing method for breeding behavior (singing, mating, dancing, hatching, etc.) were observed and recorded. The purpose is to explore the behavior rules of captive breeding Hooded Crane, providing a favorable scientific basis for Hooded Cranes breeding in captivity.The results are as follows:the mating period of the Hooded Crane’s major proportion of activity time allocation is body caring 24%, walking25%, standing 16%, feeding 15%, pacing 9%, reproduction8%, resting 2%. Each behavior between the sexes were not significantly different in the hooded crane; after entering the incubation period, all acts of gender Hooded Crane also no significant difference in the proportion of time, and the proportion of breeding behavior account for more than half of the overall behavior of the ratio, the proportion of various other acts were less than 10%. Enter the nursery early period, female Hooded Crane’s foraging behavior account for more than half of all acts, other acts proportion is still low, the performance of the main actors of the male hooded cranes are walking, standing and foraging, young cranes’mainly performance are walking, standing, resting, lying, into the later period adult crane gradually returned to mating behavior of time allocation, young cranes crane parental behavior similar proportion, and still lying.Hooded Crane with two sexes and young crane exhibited certain rules of conduct daily rhythm, are not significantly different mating behavior of each period the proportion of the sexes Hooded Crane, most acts are within the 10-25% range and low volatility and lying behavior of total days after entering the nesting incubation behavior of each period the proportion of the highest value (about 50%), other acts are in the ratio of about 10%, the female hooded crane nursery each period showed a higher proportion of foraging behavior, the proportion is between 40-60%, male hooded crane show foraging, standing and walking as the main actors, young cranes will still walking, standing, lying.Hooded Crane breeding at different stages of the utilization of cages five regions is insignificant, the utilization of the nest area hooded crane was 40% at mating period, followed by the central region of 23%, D area is 21%, A feeding area 14%, the lowest for the use of regional E zone, accounting for 3%. After entering the incubation stage, the utilization of D region increased significantly, accounting for 41% of the entire area of the nest area utilization is still high as 26%, the central region of 19%,15% feeding zone, E zone rise significantly,This accounts for 10%; pre-nursery for young cranes feeding frequently high, so the feed zone rates as high as 44%, followed by 33% of the nest area, the central area 23%, D district 3%, the E region is not use of pre-nursery late with no significant difference in the utilization of the male hooded crane utilization increased DE districts.
