Range Description

Sylvia undata is restricted to southern and western Europe and north-west Africa, where it is patchily distributed but locally common to very common in Spain (including Balearic Islands), Portugal, Andorra, Morocco. Algeria, Tunisia, France (including Corsica), United Kingdom and Italy (including Sardinia) (del Hoyo et al. 2006). The European breeding population, which constitutes more than 95% of the global population, underwent a large decline during 1970-1990 (Tucker and Heath 1994). The stronghold is located in Spain which holds 983,000-1,750,000 pairs (V. Escandell in litt. 2009), but the population here decreased by 4.6 % per year between 1998-2011 (V. Escandell in litt. 2012). France holds the next largest population (150,000-600,000 pairs) but the trend here is unclear. Trends are unknown in Portugal (10,000-100,000 pairs), Italy (10,000-30,000 pairs) and Andorra (c.20-30 pairs) (BirdLife International 2004). In the UK it has recently increased rapidly and extended its range northwards, reaching a total of 3,214 territories in 2006 (Wotton et al. 2009). If trends in Spain are reflected elsewhere in Europe, the European breeding population may have declined nearly 30% over the last 12.3 years (three generations).
