Application of point count method in forest birds survey

Point count method has the advantages of being easy to implement and allowing randomization and systematization in sampling, and is particularly suitable for counting birds in fragmented or spatially complex habitats. Because of this, it has become the most popular method for counting forest birds. In this paper, the assumptions, types, and limiting factors of using point count method in bird survey were introduced, with the focus on the appropriate selection of sample size, sampling points and sampling time, and the durations of efforts. The disadvantages of point count method were also pointed out, and the use of this method in conjunction with net-catch was suggested, aimed to improve the accuracy of bird survey.
