Conservazione

The species is still common with an estimated global breeding population of 9.4 million. However, its numbers have declined with the loss of suitable wetland habitat and wholesale draining of marshes will lead to local extinction. Still, the species is widespread enough not to qualify as threatened according to the IUCN.
