Long-distance migrant passerine breeding in mires of flooded plains in C and E Europe. There has been a steep decline in recent decades due to habitat destruction. Most remaining populations are in Poland and Belarus, with some in Lithuania and Russia and a relict population in Pomerania, Germany. Winters in flooded Sahelian grasslands in W Africa, S Mauritania, Senegal and Mali (Salewski et al. 2009, Poluda et al. 2012).

Conectividad global para Carricerín cejudo

Migrates W in autumn from the breeding grounds, with the whole population then more or less following the NW coasts of Europe to France (Julliard et al. 2006, Jiguet et al. 2011), then traversing Iberia to reach Atlantic W Africa. Data-loggers show that adults from Lithuania and Belarus move inland later in winter, e.g. to Mali (Salewski et al. 2013, Tanneberger & Kubacka 2018). Spring migration is more direct - from W Africa to the breeding grounds above the W Mediterranean basin.

Recuperaciones por condición para Carricerín cejudo

The majority of recoveries are of first-year birds ringed on autumn migration and later recaptured on migration, with few on breeding sites. Very few (<1%) Aquatic Warblers have been found dead. Winter recoveries in Senegal in Dec-Feb are a largely a result of a concentrated effort to study the species in the Djoudj National park in the 2000s. Recent effort to ring migrants in the W and SW has also increased the numbers of recoveries. Further developments in tracking might provide new insights for this poorly known species in the future.

Movimientos anuales para Carricerín cejudo

The first migrants recorded in W Europe in autumn include a higher proportion of adults than later in the year, illustrating the earlier migration of experienced individuals. There is no detailed information to compare the movements of breeding populations from C and E Europe, although adult males breeding in Lithuania and Belarus have been tracked with light loggers (Martin Flade & AWCT pers. com.).

Conectividad por mes por región para Carricerín cejudo

Autumn migration in W and SW Europe starts during the last dekad of Jul, peaking mid-Aug, althought there are some late records of migrants in mid-Sep, including adults with heavily worn plumage. Spring encounters are along the Mediterranean coasts of Spain, France and Italy during Apr, reaching the breeding grounds in May. From adults tracked with light loggers, they cross the Sahara mid-Aug-mid-Sept in autumn, and mostly in the first two dekads of March in spring (Adamik et al. 2016).
