Researchers from the Department of Zoology at the Poznan University of Life Sciences participated in a large-scale, long-term study of the effect of climate change on the production of young in more than 100 bird species. The results of the research were published in the prestigious scientific journal Proceedings of the National Academy of Sciences.

According to the study, which was carried out with the participation of Zuzanna Jagiełło, a PhD student, as well as Dr Janusz Kloskowski and Dr Marcin Tobółka, 201 populations of 104 bird species from all continents were examined over the period 1970-2019. It was shown that reproduction among most species is declining, but that these changes vary between species and even between populations of the same species. 

Migratory birds and those with larger body sizes show a decrease in reproductivity with increasing global temperatures, while sedentary, small-bodied species are raising more offspring. Species that have several broods per season also show an increase in the number of young.
