A recent study published in the journal Polar Biology indicates that earlier snowmelt due to climate change in the Arctic is leading to earlier nesting by Arctic breeding birds. So far, the birds seem to be adjusting their breeding schedules to coordinate with changing conditions. It is not known whether the birds will be able to continue to adjust or whether a threshold will be reached at which further adjustment is impossible. Artic nesting birds include many of the shorebirds that migrate through Ohio.
