Dunnocks breed in variety of scrub and woodland/ forest habitats with dense undergrowth, from sea level to the upper tree line. In W Europe they often occupy hedges, farm woodland, suburban and urban gardens (Hatchwell 2020). Widely distributed from the British Isles & the Iberian Peninsula to the Ural Mts, with the highest abundance in W & C Europe (Keller et al. 2020). Intra-European migrant - high-latitude populations are migratory, while those from mid- and lower latitudes are partially migratory, altitudinal migrants or resident.

Conectividad global para Acentor común

Diurnal migrant moving on a broad front (Michalik et al. 2020) with altitudinal migration in C & S Europe. General movement pattern in migratory populations follows NE-SW direction. Breeding populations from NW, W & S Europe are mostly resident or make short, within-region movements. Birds breeding in the Low Countries take SW routes to winter in SW France and the Iberian Peninsula, S to Morocco. N European birds move SW, those from Scandinavia are encountered mainly in W & SW Europe, while the Finnish population migrates mainly to C & SC Europe (single encounter in Greece). The C European population winters in SW & SC Europe, some birds reaching N & NW Africa (Algeria, Morocco). Birds breeding in the Baltic countries and N European Russia winter in N Italy and adjacent areas of SC Europe.

Recuperaciones por condición para Acentor común

There were few recoveries before the 1990s, with increasing numbers in the 21st century. Encounters occur year-round, with a slight peak (22%) in Sep-Oct (autumn migration). Encounters in May-Jun are largely of adults, while from mid-Jul to Nov they are mostly juveniles. Most recoveries are in NW Europe (61%), with many also in W, C, N & SC Europe (37% combined). Recoveries of birds found dead have decreased from 58% pre-1961 to 2% after 1990, while those based on live birds markedly increased from 40% pre-1961 to 98% after 1990, largely due to an increase in recaptures. Shooting accounted for few recoveries - mainly in the past (4% pre-1961) - primarily in the W & C Mediterranean region.

Movimientos anuales para Acentor común

Post-breeding dispersal and autumn migration in migratory populations start from Aug, with movements concentrated in Sep-Oct and progressively decreasing in Nov. Local breeders have mostly left the N European breeding grounds by the end of Nov. Wintering areas in NE Spain are occupied between mid-Sep and mid-Apr (Pons 2001). The very few encounters in N Africa come from Nov-Mar. Spring migration takes place from late Feb, but mostly in Mar-Apr. There are sedentary populations in the British Isles, W, SW and S Europe - the latter three regions receive most of the migrants originating from N, C and partly E Europe. Long-distance recoveries from SE Europe are almost lacking, this region possibly holds wintering birds primarily from N European Russia.

Migratory and resident strategies may both occur in any population (Csörgö et al. 2001, Bønløkke et al. 2006, Bairlein et al. 2014). Birds from the migratory populations start dispersing as early as late summer, with most autumn migration in early to mid-autumn. In N Ukraine the species migrates in autumn almost equally to W & SW, based on visual data (Khymyn 2020). In C Europe autumn migration lasts from mid-Aug to mid-Nov, progressing N to S at a rate of 50-60 km/day (Hudde & Vohwinkel 1997). The migrants from N, C and to some extent E Europe join the local resident populations in W & S Europe during winter. Wintering sites are occupied until early to mid-spring, when return migration begins. N European populations undertake the longest migrations on the continent. The Black Sea region mountain populations undertake mostly local altitudinal movements.
