Abstract

The influence of weather variables (visibility, windspeed, temperature, precipitation, cloudiness, and duration of sunshine) on growth of Little Auk chicks was analysed by means of stepwise multiple regression. We found a statistically significant negative influence of precipitation on chicks 1-5 d old, a negative impact of wind, and a positive effect of visibility on the growth of chicks older than 5 d. Based on a day-to-day analysis we found five days throughout the chicks' development in which their growth was influenced by visibility or precipitation. Characteristically, we detected the influence of these variables on chicks' growth in times of changing weather conditions. Air temperatures measured in three nests were stable and close to ambient temperature. Only in one nest was the temperature significantly correlated with ambient temperature. We conclude that some weather variables clearly influenced changes in body weight of Little Auk chicks, although their effect on postnatal development was weak.
