Red Turtle Dove Streptopelia tranquebarica and Spotted Dove Streptopelia chinensis are common native species in Taiwan, and coexist on TungHai University Campus. According to competition exclusion principle, if two competing species coexist in a stable environment, their resource will be partition, or one species will extinct. In Avian Ecology , the birds avoid competition by the isolation in spatial , temporal, and feeding. The aim of this study is to identify the niche relationship between Red Turtle Dove and Spotted Dove .
The result showed that these two doves coexist in the same area by the isolation in the feeding and activity habitat selection. When they are both in breeding season , because the requirement of nest sites and food resources are increased, the niche overlap indexes are also increased. Because more detail data in diets descriptions are lacked, it is hard to identify the competitions between two species exist or not , and the degree of competition.
