The Study Of Feeding-nestling Behavior Of White Spoonbill(Platalea Leucorodia) In Breeding Season In Qixinghe Nation Nature Reserve, Heilongjiang Province, China

White Spoonbill is a large wader belong to Threskiorothidae, and was listed as the Second Category of nation protection birds, From May to June in 2015, the technology of camera trapping was firstly used in Qixinghe National Nature Reserve of Heilongjiang Province. There were 5 White Spoonbill nests to be laid 15 Camera trapping and 19000 effective data were got. The results showed:both the adult took responsibility of feeding during the brooding period. A total of 247 times of feeding were recorded, and earlier stage, middle stage and later stage were 80 times,124 times and 43 times respectively. The peak period of feeding turned out to be 3:00-4:00 and 17:00-19:00 in a day. The behavior of protecting stopped until 10 days-age,406 times of protecting behavior and 6530 minutes in total; there were significant negative correlations between protecting time and the youth. There were 679 times of Nest-building, 5:00-7:00 and 17:00-19:00 turned out to be the peak period in earlier stage and middle stage, no peak period in later stage. Preening behaviors were continued in whole brooding period, 1129 times in total. The preening behavior happened at 4:00-5:00 and 18:00-19:00 turned out to be the peak period in a day. The resting behavior were divide into standing-rest and lie-Resting, and standing-rest began at May 20 stopped until June 26,1138 times of standing-rest and 16423 minutes in total; but lying-rest behavior happened after 12 days age of young birds or raining times in middle stage and later stage only,342 times of standing-rest and 4866 minutes in total.The strong active regularities between parents were recorded during the whole brooding period.They exchanged at 19:00-20:30 in nest, one looking for food far from the nest, and usually returned at 3:00-4:00 the next day, then began feeding the youth; other times they exchanged one time during 3-4h, ensured that there was one of the adult keeping in the nest and the other one looking for food out of the nest. Some behaviors happened accidentally, such as alerting, deporting, shooking and driving. Statistics showed that the proportion of each behavior of adult Eurasian Spoonbill during brooding period were as follows:Standing-rest 28.76%, Preening 28.68%, Nest-building 17.16%, Protecting 10.26%, Lying-rest 8.64%, Feeding 6.22%, Others 0.28%.
