It is a commonly kept bird in zoos across Europe and Asia. In Europe there have already records of birds escaped from the cages and breed in large numbers in the wild. It was in year 1984 when the first Sacred Ibis individual in the wild was recorded in Guandu, Taipei. Since then, the Sacred Ibis populations had spread to the various coastal wetlands across many cities and counties in the western Taiwan. Furthermore, there are also records of clustering breeding in this species. Therefore they are now regarded as an invasive species in Taiwan. The population surveys of Sacred Ibis were carried out twice each during the breeding and non-breeding seasons in year 2009 across various counties and cities in western Taiwan as well as at major estuaries in Yilan County. Furthermore, behavioral monitoring and reproductive analysis were carried out in Guandu area. We have found record of Sacred Ibis in Taipei, Hsinchu, Miaoli, Taichung, Yunlin, Chiayi and Tainan. The population size is estimated to be between 500-600 individuals. In Guandu of Taipei and Nanliao of Hsinchu it is confirmed that there are breeding and nesting colonies while in Guandu wetlands of Taichung county as well as in Houlong-Xikou of Miaoli County there are records of joint feeding of adult birds with juvenile birds who had just left their nests, indicating that nesting clusters possibly occur in the Central area of Taiwan. Research methods during this year included: (a) the number of Sacred Ibis in Taiwan`s population, estimate 4 times in this year; (b) Testing the hatching success rate by used egg oil in different date, and calculate the best operation time. And we will make a video film to explain our processes.埃及聖&#40558族群成長繁殖巢區生殖成功Sacred Ibispopulation growthbreeding areabreeding success
