- Аннотация: In the premigration period, weather plays a role in the ability of animals to accumulate energy stores before the onset ofmigration, affecting survival. In the context of rapidly changing climate, our goal was to study the effect of short-term weatherconditions on the Common Crane (Grus grus) movement in the premigration period. We analyzed the daily distances andthe maximum displacements using GPS telemetry data. We studied the relationship between weather conditions (averagedaily temperature, daily precipitation, and wind speed), age, the presence of offspring, and crane daily movements. The studywas conducted at premigration staging areas in the European part of Russia. We found no differences in daily movementdistance between adults with and without chicks and subadult individuals. A positive relationship between daily distancesand maximum displacements and wind speed, and a negative relationship with average daily temperature and precipitationwas observed. The influence of weather conditions on movement patterns can further affect the quality of migration in therapidly changing climate.
