Not everyone is shrinking: increases in body mass and wing length in a Sand Martin (Riparia riparia) population in northwestern Italy over two decades

open access: yesIbis, EarlyView.
In recent decades, vertebrates, particularly birds, have exhibited notable morphological changes in response to climate change. In birds, these temporal trends usually entail a decrease in body mass and an increase in wing length, sometimes interpreted as a compensatory strategy to maintain migration.

open access: yesIbis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.
