Searching for the causes of decline in the Dutch population of turtle doves Streptopelia turtur

Abstract

Adult survival was therefore estimated from ringing and dead-recovery data of Turtle Dove (Streptopelia turtur) collected between 1930 and 2017 in the Netherlands. The data is divided into birds ringed as adults, and birds ringed juveniles (i.e. either as nestlings or fledged first calendar-year birds). Survival was estimated using a Seber dead-recovery model with S and r parameterisation in RMark.
