The ongoing decline of the breeding population of Black-tailed Godwits Limosal l. limosa in the Netherlands is not explained by changes in adult survival
The Black-tailed Godwit Limosa limosa is a characteristic breeding wader of wet grasslands in the Netherlands which has suffered a strong population decline since the 1960s. Low breeding success has been implicated as the main driver of this decline and here we examine whether changes in adult survi...
