In this study, although the design adopted a standardized fixed-point counting method and attempted to make up for the insufficient number of sample points by increasing daily observation time and multi-day repeated observations, there are still some design limitations. First, only one observation point is set up for each habitat, and the spatial representation is limited, making it difficult to capture the heterogeneity within the habitat. Secondly, although multiple observation dates are set, the statistics are mainly used for the daily statistics of 11:00 and 13:00, which may miss the peak activity of many birds in the early morning or evening, which may affect the true reflection of species abundance. In addition, the total distance between the three sample points is only 230 meters. Although a certain spacing is maintained between each point, the short distance movement of birds may still lead to the risk of individual repetition counting, reducing the independence and accuracy of the data. Furthermore, some species have a small sample size, which affects the reliability of statistical analysis. Nevertheless, the design successfully captured the habitat preferences of some birds under limited resources and time, especially providing a preliminary scientific basis for the differences between low-shrub forests and shore forests. Future research can improve the representativeness and statistical effectiveness of the research by increasing the number of sample points, covering a wider time period and expanding the spatial scale.
