Effects of climate variables on the White Stork (<i>Ciconia ciconia</i> L.) productivity in a long term study

Abstract We analysed the effects of weather and climatic patterns on productivity White Stork in Hungary between 1958 2017, using i) linear mixed effect models (LMM), ii) LMM-s extended by a single random variable or nested combination; iii) fixed iv) an additive model selected variables. As preselection, following variables were identified with substantial support: March mean temperature, precipitation, April June precipitation (negative), July temperature. The slight increase number fledged chicks over 59 years could be result increasing but itself it might not strong enough to prove that climate change will overall benefit productivity. Higher temperature values are favourable, probably because higher biomass, providing more prey, high is unfavourable until thermoregulation developed. Decreasing amounts may cause loss wetlands as suitable feeding sites. Extreme important complement picture given change.
