Populations from S Europe tend to be resident; migratory behavior increases with latitude. All migratory European populations/individuals show a clear NE-SW axis of movement with obvious parallel migration and therefore strong connectivity with winter distribution mirroring breeding distribution. Birds from NW and W Europe to W Scandinavia move SW to Iberia, with some reaching NW Africa. Birds from E Fennoscandia to C and E Europe overwinter from E Iberia/S France to Italy. 

Recuperaciones por condición para Pardillo común

The vast majority of recoveries (almost 90%) are of birds found alive, mostly recaptures by ringers (~80%). Before 1991, however, around 40% of recoveries were of birds found dead, sick, wounded or shot. This pattern clearly changed in more-recent years when these fates accounted for less than 5% of recoveries, with ~98% being of birds seen alive, mostly recaptures from ringing.

Movimientos anuales para Pardillo común

Migration in autumn starts in Sep in N latitudes, clearly occuring in Oct across much of Europe. Birds stay in their wintering sites mostly Nov-Mar/Apr with return passage, across much of Europe, peaking in Apr. Arrival in the most N breeding quarters may be as late as May.

Conectividad por mes por región para Pardillo común

Breeders from W Scandinavia migrate through C Europe mostly in Oct (autumn) or Apr (spring) and are mainly at their wintering sites Nov-Feb. The relatively longer-distance migrants from NW and W Europe are mainly on passage through the W Pyrenees in Oct, and then overwinter in Iberia. In  S England and France most movements are short-range. The concentration of encounters in Belgium is mainly due to birds on passage from Scandinavia, en route to SW Europe. Breeders from C Europe are found from E Iberia to Italy in Nov-Feb; those from E Europe are encountered from southern France to the Black sea area.

There are data from NW, W, C and N European regions. Recent analyses of recovery data show high connectivity between breeding and non-breeding areas for pipilans, the British & Irish subspecies (Dunning et al. 2020), which is a short-distance migrant. Mainland populations of flavirostris, roughly follow a N-S or NW-SE axis of migration.

Overall, most recoveries are of recaptured birds  (91%). This percentage is similar between periods: changing from 86% before 1961 to 97% from 1991 to present. There is a very high concentration of recoveries in Belgium, most in Oct-Nov, but also in Mar, as a result of intensive ringing campaigns using sound-lures designed to capture actively migrating finches.

Movimientos anuales para Pardillo piquigualdo

Movements S to lowlands of coasts and estuaries, principally around S Baltic and N Sea, start from late Aug-late Sep; migration peaks in Oct-Nov. Twite are present in C Europe from Oct, remaining to Mar-Apr. Birds return to the breeding quarters as soon as weather conditions improve, which can be as early as Jan, up to Apr. N Scandinavian populations reach their breeding sites by Apr-May.

Birds from the British Isles mainly overwinter there (Raine et al. 2006), but some cross the English Channel and are the mainly found in Belgium in Oct-Nov, but many of these of birds are probably still on passage and may go as far as N Italy (one encounter). Scandinavian birds (mainly from W Norway) move N-S, with most recoveries in winter (Oct-Mar, concentrated in Nov-Feb) in S Scandinavia to northern half of C/E Europe.

Manx Shearwater by Helen Smith

Manx Shearwater P. puffinus is a monotypic black and white medium-sized tubenose of the Atlantic Ocean, breeding on islets off Iceland, Faeroe Islands, British Isles and NW France, but also Atlantic islands (Azores, Madeira, Canary Islands). Also breeding off NE Canada and Massachusetts. In winter, distributed across the whole Atlantic, down to the Cape of Good Hope and the Cape Horn, but absent from the Gulf of Guinea. Closely related Yelkouan Shearwater P. yelkouan is endemic to the Mediterranean, breeding from French islands to the eastern waters, wintering in the Black Sea too. Balearic Shearwater P. mauretanicus breeds only on Balearic Islands, and disperse in the Atlantic, especially the Bay of Biscay and Chanel, in the non-breeding season.

The available data concern predominantly puffinus, ringed in the British Isles, and dispersing to many directions, to the West, South West and South. There are some recoveries to very long distances, in southern Argentina and South Africa. There are also numerous recoveries in Europe, across British waters, the North Sea and in the Gulf of Biscay. Tracking data of puffinus concern only the breeding season (Guilford et al. 2008; Wischnewski et al. 2019). Very few local recoveries of yelkouan along French and Italian coasts. Few recoveries of mauretanicus too, but more spread around Balearic Islands, from the Algerian coast to the Bay of Biscay.

The relative dates of recoveries along South American coasts suggest a progression towards the South as the non-breeding season progresses, with records along Brazil in October-November, and along Argentina from November to February. Recoveries in the Bay of Biscay are mainly from March to May, suggesting that Manx Shearwaters moved to these waters on their way back to the breeding colonies. Movements between breeding colonies occur between March and September.

Most recoveries of puffinus concern movements between breeding colonies during the breeding season, mostly from March to October. Recoveries along South American Atlantic coasts have been obtained in all months, but less numerous from May to September. Recoveries far South off Africa are from November and January. There is an extra-limital recovery of a British Manx in Australia in November 1961. Balearic birds are recovered outside the Mediterranean mainly in July to September, with birds returning to the Balearic Islands from November onwards.

Most populations are resident, or undergo local winter dispersal to lower altitudes or coastal farmlands. Some migration in a south-westward direction, e.g. from the North to Central Europe to the West of Europe, or from East to South-Central or South East Europe. Movements also attested by winter recoveries in e.g. Iberia and Mediterranean coast of France, where the species does not breed. Possible long-distance movements from Central Russia as suggested by regular Mediterranean wintering records of an Asian sister species in Europe (Pine Bunting Emberiza leucocephalos), though no ringing efforts in the extreme East of the range. Reported wintering site fidelity in migratory populations wintering in NE Spain (Herrando et al. 2011), also changes in the wintering grounds between different years and movements due to cold spells (Cramp & Perrins 1994). No evidence of sex- or age-specific dispersal strategies (Lehikoinen et al. 2017).

Recuperaciones por condición para Escribano cerillo

As for many passerines, recoveries are mostly birds retrapped alive (globally ~80%). This has increased as a result of increased ringing effort since the 2000s, especially in NW and N Europe. Half of the recoveries before 1961 were of dead birds, but this has fallen to ~3% in recent years.

Most yellowhammers leave the northernmost part of the species range in October, and return in April. Records of breeders away from their region (North, East, …) are scattered from the first decade of October to the second decade of April. Movements from the West to Mediterranean wintering grounds seem to be more restricted in time, from late October to early March. The large ringing effort on in the North-West provide evidence that yellowhammers of ssp. caliginosa do not leave the British Isles.

Conectividad por mes por región para Escribano cerillo

Difficult to describe connectivity among months as most birds stay in their breeding region throughout the year, but some links can be described. In the North, movements within the region in October to move southwards, April to come back on breeding grounds, with very few recoveries elsewhere in Europe, despite an important ringing effort. Birds from Central Europe are present year-round in their region, but some recoveries in Mediterranean countries from mid-October to early March (Gyurácz et al. 2017). Less ring recoveries of caliginosa in Northern Scotland in mid-winter, but might be due to low ringing effort to recapture birds. Only two recoveries of British birds on the continent (in November and January), in countries with important winter ringing effort, so anecdotical.

Conectividad global para Gaviota tridáctila

A very pelagic gull (e.g., Bogdanova et al. 2011), so many recoveries show natal/breeding dispersal, rather than breeding-wintering migratory movements. Philopatry assessed to be relatively low (Coulson & Nève de Mévergnie 1992). Overall, dispersal occurs widely over N Atlantic, rarely to S Atlantic (W African coasts) or other areas (Mediterranean up to Ukraine). Return to breeding colonies normally not before the third summer, and adults move less than immatures (Barrett 1997). Birds from N colonies tend to winter N than birds from S colonies (Barrett & Bakken 1997), though connectivity is weak, overall, a finding also supported by genetic studies (McCoy et al. 2005).

Recuperaciones por condición para Gaviota tridáctila

Overall, most recoveries due to birds seen alive identified with leg ring(s) or other means (53%), followed by recaptures of ringed individuals (32%). Up to 1990, a high proportion (ca. 50%) of recoveries due to birds found dead, sick/wounded, and yet also a proportion of recoveries due to shot (up to 27% before 1960). From 1990 to present, a high majority of the recoveries are due to birds found alive, most (59%) identified with leg ring(s) or other means.

Large, predominantly black waterbird, relying almost entirely on fish. Breeds in small to very large colonies, found both in freshwater as well as marine habitats. Very large, near cosmopolitan breeding range. In Europe, disjunct breeding distribution from France and UK east to Black Sea region, Belarus, Baltic states, and N to northernmost Norway. Northern and eastern populations migratory, western and southern populations largely resident with some dispersal. European population 401,000-512,000 breeding pairs with increasing trend. Prone to drowning in fishing nets, some populations controlled.

UK birds move due S to Atlantic coast of France and NW Spain. Birds in W Europe largely resident, Some move to France, fewer Spain and Tunisia. Central European breeders mainly move SW, some reaching Tunisia and French and Spanish Mediterranean coasts, minority moves SSE to Greece. Northern and eastern populations move longest, predominantly to Spain and Tunisia, one reached S Mali.  Males stay closer to breeding areas than females (Bregnballe et al. 1997). Minority of eastern populations move due S to Greece. Birds breeding northern Black Sea coast move to Middle east in winter or remain in area. Birds breeding Wolga Delta winter southern coast of Caspian Sea or further S to Persian Gulf.

Almost two-thirds of all recoveries are of dead birds; among which 20% are shot or otherwise taken, remainder is other causes of death. Reports of shot birds biased towards France and Italy, few in N. Europe, almost none in low countries. Dead birds from other causes are relatively evenly distributed in coastal areas throughout Europe. Ringing recoveries very few, ring readings almost one-third, mainly in UK, Netherlands, Denmark and Germany.

During winter Nov-Feb most re-encounters in N. Africa, SW, SC, W and C Europe, UK/Ireland and coast of Norway. From begin Mar numbers in NW Africa and Middle East decrease, fewer in France and fewer on Norway coast. From begin April N. Africa and SE Europe largely vacated. Begin May re-encounters more concentrated in colonies in NW, W, C and N. Europe. Begin Jun. whole of S. Europe vacated and marked concentrations in low countries, Denmark, coast of UK and France and Baltic coasts. First encounters in northernmost colonies begin May, until mid Aug. First birds return to N. Africa in Oct, more dispersed re-encounters in inland France, Spain, Italy. Birds re-appear in Middle East only end Nov.

Winter re-encounters in Nov-Mar in N. Europe entirely confined to coast, and connected to northernmost breeding sites in Jun-Jul. Breeding birds in May-Jul connect to wintering sites in France, Spain, Italy and NW Africa. Few birds winter in E. Europe, encounters in Nov-Mar on Baltic, Black Sea and Caspian Sea coasts connected to close-by breeding sites. Breeding birds in May-Jul connect to wintering sites scattered over C, SW, SC and SE Europe in Oct-Feb. Wintering birds in W. Europe Oct-Mar connect to breeding sites in UK and Ireland, Denmark and Baltic in May-Jul, but not to Northernmost colonies. Breeding birds in May-Jul connect to wintering sites in France, Spain and Tunisia in Oct-Mar. Breeding season encounters in May-Jul in SW, SC and SE Europe mainly connect to more northern breeding sites in May-Jul.

Michele Mendi

A long-distance migratory passerine, breeding from W Europe/NW Africa to C Asia, and wintering across the Sahelian belt up to E Africa (BirdLife International 2021). In Europe, it avoids the coldest regions, incl. Scandinavia, the Baltic area, E Europe, Iceland, Ireland and the N half of UK; also some main mountain ranges like the Alps.

Conectividad global para Ruiseñor común

Few recoveries S of the Sahara, hampering us to obtain firm conclusions only using ring-recovery data. Recoveries in Europe/N Africa draw parallel migration patterns, with birds breeding in regions further W also passing further W (Iberia, NW Africa) than populations from further E regions (C Mediterranean, or SE Europe). Recent works using light-level geolocators show high connectivity in Africa (Sahelian belt), due to the existence of parallel migration patterns (Hahn et al. 2014), thus confirming what is sensed in Europe/N Africa. Detours in autumn larger for the W population than for the C/E European populations (Hahn et al. 2014). W/C nightingales change more often their wintering sites (>80%) than E birds (18%) (Hahn et al. 2014).

Recuperaciones por condición para Ruiseñor común

Most recoveries (96%) due to birds captured alive thanks to ringing. Before 1960, however, almost 30% of recoveries were due to birds found dead/sick/wounded. Since then, most recoveries fit to the general pattern show above.

Movements to S patent in Sep in Europe. Already in Oct, the amount of recoveries in Europe drops substantially hence reflecting that most birds would be then in Africa. Recoveries in the Sahelian belt from Nov to Mar (though take this with caution due to low sample size). Return to Europe patent in Mar. Recoveries suggest arrival to breeding quarters mostly in Apr. Few recoveries in Europe in winter. Nightingales wintering in S Europe (e.g. Guadalquivir region in S Spain) is becoming a frequent phenomenon (Morganti & Pulido 2012). Duration of autumn migration estimated to be ca. 70 days, and the spring one 30 days (Hahn et al. 2014).

Detailed data only possible if combining ring-recovery data with results from light-level geolocators. Departure from breeding sites in early Aug for the W/E populations, ca. 2 weeks later for the C population (Hahn et al. 2014). Important stopovers in Aug/Sep in: (1) W birds: Iberia, S France, Italy (more rarely), W/E Atlas; (2) C birds: Italy, E Atlas, Lybia; (3) E birds: SE Europe, E Sahara (Hahn et al. 2014). Recoveries in Mediterranean islands very common (e.g., Rubolini et al. 2005; Gargallo et al. 2011). Arrival to winter quarters in Oct. Departure in spring from Africa rather similar across populations, in Mar. Arrival to breeding quarters in Europe in Apr.
