A case of early breeding of Pied Avocet (Recurvirostra avosetta)

Abstract

On the 14th of April 2022, during a periodic bird monitoring activity in a wetland area located in the municipality of Mirandola (Moedna), Northern Italy, a breeding pair of Pied Avocets Recurvirostra avosetta, were recorded along with chicks aged approximately 2/3 days old. This is clearly a case of extremely early breeding seeing as, in Italy, Pied Avocets lay eggs from late April to June, based on adequate weather and environmental conditions. As for this specific case, an estimated cause of such anticipated breeding may be the previous very mild Winter months with little rainfall as well as the breeding ground offering shelter from predators.
