“Using a four-decade specimen series of 70 716 individuals of 52 North American migratory bird species, we demonstrate that increasing annual summer temperature over the 40-year period predicts consistent reductions in body size across these diverse taxa.”
A more recent study, looking at 52 species of migratory birds passing through Chicago, again found both reduced body weight and increased wingspan. https://t.co/Ejl9ZmcSH1
