For home range analysis, we applied the Minimum Convex Polygon (MCP 100%) and Kernel Density Estimation (KDE 50%, 95%) methods to define the core habitats (core habitat) and overall home ranges. The results showed that black-tailed gulls ( Larus crassirostris) primarily used coastal and forested areas adjacent to the coast during the breeding season. Meanwhile, outside the breeding season, they tended to expand their home ranges to include ports and industrial areas. In the case of the black wood pigeon ( Columba janthina), individuals BW1 and BW3 exclusively used the Japanese black pine community ( Pinus thunbergii) throughout the day and night (100%), indicating a stable habitat preference. In contrast, individual BW2 exhibited different habitat uses, using both the Okamoto maple Korean beech community ( Acer okamotoanum–Fagus engleriana) (41.0%) and the Japanese black pine community ( Pinus thunbergii) (39.9%). Analysis of habitat use patterns by time of day revealed that black wood pigeons tended to explore a broader area for foraging during the day. Meanwhile at night, they moved into densely forested areas with a high concealment capacity. Additionally, seasonal changes influenced the movement patterns of black-tailed gulls, as they shifted from natural habitats to areas with high human activity after the breeding season. This study has provided important insights into the spatial ecological characteristics of island-dwelling birds and underscores the need to establish habitat conservation strategies that account for species-specific and seasonal differences. In avian home-range studies, it is crucial to employ various analytical methods and approaches to assess the long-term ecological impacts on home range dynamics.
