Parents adjust their foraging effort according to the chick and own body condition dual strategy is one of tactics parents replenish reserves while feeding chicks. During post-breeding season, seabirds disperse recover prepare for next breeding season. Recently, we discovered Black-tailed gulls (Larus crassirostris) around Korean Peninsula occasionally long trips during late fledging, however, our understanding behavioral patterns fledging post-breeding, as well its inter-colonial differences, remains considerably limited. Here, employed 92 GPS trackers adult from six colonies peninsula (Yellow Sea—three colonies, South Sea—one colony, East Sea—two colonies). To determine investment suggested flight efficiency in each trip ratio maximum distance (i.e., straight line distance) total sum all consecutive trip). Overall, mean were lower than 57% (40.76 ± 13.07%) whereas that short over 74% (80.87 4.03%). This may suggest visited more site they flew directly between colony invest juvenile. Moreover, longer with higher observed Sea indicate a balance costs (such energy expended or food competition near sites) benefits (quantity quality obtained). Our findings revealed behavior post breeding, across which have different pressures proximity site.

In this study, GPS trackers were attached to black-tailed gulls (Larus crassirostris) breeding on five islands in Republic of Korea during April and May 2021, their flight frequency, behavioral range, altitude compared after the season. During season, frequency was lowest Dongman Island (28.7%), where mudflats distributed nearby, range activity narrow. contrast, it tended be high Gungsi (52%), colony far from land, resulting a wider activity. Although increased post-breeding season (42.7%), decreased other islands. The mean highest Napdaegi Island. most areas, higher than that However, lead lower non-breeding home expanded with no significant difference time between seasons. Our findings reveal exhibit varying ranges altitudes depending geographical location. As generalists, display flexible responses environmental changes, indicating behavior adapts evolving environment over across regions.
