Small warbler, feeds on insects and spiders; in autumn also berries. Nominate trochilus: W Europe to S Poland and Romania; acredula: Scandinavia to Siberia (Yenisey River); yakutensis: E Siberia (Taymyr Peninsula to Anadyr River). Unlike similar Chiffchaff P. collybita, extends widely into arctic but only marginally into Mediterranean region. Differs in being a bird less of mature woodland than of scrub, second growth, and transitions to more open habitats. Although the population is decreasing, the population is large enough to assign the status of Least Concern. All populations migratory, wintering extensively in sub-Saharan Africa from S Sénégal east to Ethiopia, south to South Africa.

S. Fennoscandian birds allegedly belonging to trochilus move NE - SW: recoveries in W and SW Europe, S UK and W Africa; alledged acredula move N - S: recoveries in C Europe, Italy and C Africa; and NW – SE to E and SE Europe, Turkey, Near East, Egypt and E Africa. Migratory divide across central Scandinavia diffuse and genetic differentiation is small (Bensch et al. 1999). Few birds move E - W, found in Iceland, Shetlands and Faroer. From UK and Ireland birds move NNW - SSE, found W Europe, Iberia and W Africa. Birds from W Europe mainly move NE - SW, recoveries in Iberia and W Africa; a minority move NNW - SSE, recoveries C Europe, Italy, E Algeria, Tunesia and C Africa. Birds from C and E Europe show directions from NE - SW to NW – SE, but from C Europe there are only recoveries in W Africa and from E Europe only in E Africa.

Until 1960 52% of the recoveries were dead birds: 8% were shot and 2,8% intentionally taken. From 1961 to 1990 11% concerned dead birds: 1% was shot and 0,4% was intentionally taken. From 1991 almost all recoveries concerned alive birds. Most dead birds were intentionally taken or shot in Portugal, N Spain and N Italy; also around the Mediaranean E coast and in NW, W, C and SE Africa.

Two main migratory axes; SW (namnetum, cyanecula, azuricollIs) (Arizaga & Tamayo 2013) or SE (svecica, magna, volgae) (Collar 2005). Subspecies azuricollis recently revealed to winter in W Africa (Lomas-Vega et al. 2019)., while namnetum migrates along the coast of N Iberia (Arizaga et al. 2006) to overwinter mainly in Portugal/N Africa (Zucca & Jiguet 2002) and cyanecula overwinters from S Europe to W Africa. Migration is on a broad front, although there is some connectivity: Bluethroats breeding further east were also located further east during autumn migration, winter and spring. There are few data for svecica  outside Scandinavia, but recoveries spread across a NW-SE axis, across to India. Studies with geolocators confirm an Indo-European flyway (Lislevand et al. 2015). Few data for the E and Caucasian populations. There are few data for the E and Caucasian populations. Birds breeding in SE Russia/Caucasus have been recovered in Israel and the E Mediterranean.

Most recoveries are of birds recaptured for ringing. Before 1960 ca. 15% of recoveries were of birds found dead, including those shot or sick/wounded.

Annual Movements for Gorgebleue à miroir

Birds leave the breeding quarters soon after breeding, mostly in Jul/Aug, up to Sep in very N populations (Lislevand et al. 2015). Passage in W Europe starts in mid-Aug, peaking in Sep (Arizaga et al. 2010). By Nov, most birds already found at their wintering sites. Spring migration starts in Mar, peaking in Apr in S/C Europe and also the Indo-European flyway-associated Bluethroats (Lislevand et al. 2015),  arrival on the northern European breeding grounds (Scandinavian birds) is in May; later than for the W/C European populations. Migratory speed seems to be slow, assessed to be <200 km/day (including stopovers; Lislevand et al. 2015), though probably much faster in spring (Lomas-Vega et al. 2019).

Connectivité globale pour Cincle plongeur

Most regions show relatively short-range movements (<200 km), with the exceptions of Central, N and E Europe, where displacements of up to ca. 1000 km can be detected (though most obtained at less than 200 km). Thus, it is a majorly sedentary species, so recoveries show local natal or breeding dispersal patterns, rather than true migrations. Largest movements due to Fennoscandian populations, which move south/south-east in autumn, mostly to overwinter within the circum-Baltic region, also (more exceptionally) to Britain. In Spain, most recoveries (ca. 90%) obtained within <10 km, and only one recovery of >100 km (a bird ringed in Belgium) (Regla & Arizaga 2016). This is a general rule for the W and S populations (Tyler & Ormerod 1994, Spina & Volponi 2009).

Contrôles par Condition for Cincle plongeur

Overall, most recoveries (>90%) due to birds found alive, both recaptured for ringing and identified by other means, like leg ring(s). Before 1960, still a remarkable fraction (ca. 25%) of the birds was due to individuals encountered dead, sick or wounded. From 1990 to present, this fraction is absolutely marginal, so most recoveries come from birds encountered alive, either recaptured or identified by other means.

Annual Movements for Cincle plongeur

Natal dispersal in resident populations starts soon after young emancipate, and the timing for that can vary with altitude and latitude. In Fennoscandia, most birds found at their winter quarters by Oct, up to Mar/Apr.

Connectivité par mois par région pour Cincle plongeur

Most populations remain in the same zone for the whole annual cycle. Adults normally show high fidelity to breeding site (e.g., Tyler et al. 1990), whilst first-year birds show some degree of natal dispersal which, in addition, is greater in females (Tyler et al. 1990). Many Fennoscandian dippers abandon their breeding sites by Oct, as soon as water bodies where they live freeze. They then mostly occupy the circum-Baltic region. Return to breeding quarters patent in Apr; by May most birds are found at their breeding sites. In S Europe, where the birds breed associated to mountain ranges, altitudinal movements common (Tyler & Ormerod 1994).

Birds from Fennoscandia and Baltic show longest movements. N Italy and S France receive bulk of migrating and wintering birds from C and E Europe and act as a hotspot in Oct-Dec, but may be biased because of high hunting pressure. Few birds on autumn migration in C Europe and Italy reached Morocco, Algeria or Tunisia.

Birds breeding in N, NW, W & C Europe migrate S & SW mostly along the Atlantic coast of W & SW Europe, to a lesser extent through the W & C Mediterranean. Multiple encounters of wintering birds are spread along the whole Atlantic coastline of W & S Africa, reaching the Indian Ocean close to Mozambique. Wintering birds are encountered in the Macaronesian islands (single stragglers) and even as far as North America. Very few birds from N & C Europe take SE routes towards the Black Sea region. SC European breeders (Italy) migrate and overwinter both in the Mediterranean and along the W & S Africa coasts. The Black Sea breeding population mainly migrates to the Mediterranean Sea during winter, moving E-W. A bird marked by the Caspian Sea was recovered during winter in Sri Lanka.

Contrôles par Condition for Sterne caugek

Most recoveries occur during the breeding season, peaking in Jun (ca. 42%). The bulk of encounters (ca. 80% in total) come from W  (32%), NW (17%), N (16%) and C Europe (15%). Recoveries of dead birds have  decreased over time: from 74%  before1961 to 14% since 1991; recoveries of live birds increased considerably from 9% before 1961 to 80% since 1991. The latter is mostly due to recaptures; especially metal rings read in the field and colour-ring resightings. Shooting was an important factor in the past (26% of all recoveries before 1961 and 6% 1961-1990). Birds have been locally trapped in W Africa by children using baited hooks or nooses (Wernham et al. 2002).

Annual Movements for Sterne caugek

The populations around the North Sea show no prevailing direction for post-breeding dispersal (Jul-Aug; Møller 1981a). There is pronounced autumn migration mainly from Aug and especially in Sep. The wintering grounds along the W & S African coasts (even the furthest ones, in S Africa; Tree 2011) are reached as early as Sep; overwintering birds are encountered until Mar-Apr. Many of them depend on the local upwellings for food provisioning (Møller 1981b). Some birds from NW, W & C Europe are encountered in C Mediterranean (Italy) in autumn (mainly Sep-Oct) and spring (Apr-May). Most birds breeding in the Black Sea region migrate to the Mediterranean Sea (from Spain to Israel), where are encountered mainly Oct-Mar; some continue as far as W & S Africa. Spring movements are mainly undertaken in Mar-Apr, sometimes until May.

Connectivité par mois par région pour Sterne caugek

Dispersal movements after the breeding season take place in mid- to late summer, migration is more evident from early autumn. Wintering birds in W & S Africa are encountered mostly between early autumn and mid-spring. Most first-year and some 2-3-year-old birds spend the summer in the winter quarters (Møller 1981b). Some birds from the populations around the North Sea migrate through Italy. The Black Sea breeding population moves E-W and overwinters mostly within the Mediterranean region (Popov et al. 2012), some birds reach the Canaries (Mar). Spring migration takes place mostly early to mid-spring. Spring movements from the wintering sites in Namibia to the colonies in the Netherlands last 30-45 days (Keijl 2003). Large-scale connectivity between NW European colonies has been suggested (Fijn et al. 2014).

Small tern breeding solitary or colonially in a wide variety of flat and open habitats in coastal and inland areas, increasingly on roofs. Breeds patchily in most of Europe, also Asia and N America.  Strongly migratory, European population wintering mainly along coasts of Africa, bays, harbours, lakes and rivers. Geolocators revealed offshore wintering at upwelling seas of W Africa is common (Becker et al. 2016). Large variation in migratory strategies among individuals, but high repeatability within (Kürten, et al. 2022). European population 316,000-605,000 breeding pairs, increasing.

Movements mainly N-S, with connectivity from breeding to wintering areas in W Africa (Senegal to Ghana), and S Africa (Namibia to S Africa). Birds from NW Europe predominantly winter W Africa with just 2% in S Africa, of W European birds c.20% winters S Africa, of birds from N and C Europe c.50% winters S Africa, E European birds all winter in S, and some E Africa, but latter common based on geolocators even for C European birds (Kralj et al. 2020). Indication for leapfrog migration; birds from Finland move longest and winter predominantly in S Africa, birds from SW and SC Europe more often found in W Africa N to Mauretania. Birds from Azores connect to E Brazil and Argentina. Otherwise, few connections to both N and S America, 3 birds reached Australia, 2 India.

More than three fifth of all re-encounters are ringing recoveries or birds otherwise identified, e.g. rings being read in the field, especially after 1990 and predominantly in W Europe, especially the Netherlands and Belgium where many colour-ringing projects. Dead birds make up 30% of total, occurring equally across entire range. Although common terns are long lived, mortality during the first two years of life, between fledging and first breeding exceeds 50% and is strongly related to fledging body mass (Braasch et al. 2009). Among dead birds, 6% of total was shot or intentionally taken, especially in Denmark, France, Spain and W Africa, but after 1990 only 1% of total was.

Annual Movements for Sterne pierregarin

From mid Nov to begin Apr all recoveries are in Africa S of Sahara, then rapid Northward spread; Mid Apr concentration in Netherlands, few elsewhere in Europe, begin May concentrations in British Isles, Netherlands, Germany, few Baltic, end May all breeding sites filled, concentrations in Netherlands, Germany, Denmark, E Germany along Elbe SE to C Europe, Baltic, Finland, Black Sea and Azores. Distribution remains stable until end Jul. Quite some birds remain in Africa during summer. Begin Aug birds appear at coasts of France and Iberia, end Aug increase in W Africa. Finland and inland C Europe vacated begin Sep. Mid Sep birds leave Scotland, mid Oct birds become sparse in Europe, begin Nov very few left, mainly Netherlands. Winter encounters are odd birds, possibly long dead.

Connectivité par mois par région pour Sterne pierregarin

Connections in Nov-Mar few and local in all regions. Breeders (Jun-Jul) in NW, W Europe connect to W and, fewer, S Africa Sep-Feb, immatures also Mar-Jul. Birds passing in May and Aug-Sep strongly connected to Fennoscandia in Jun-Aug. Breeders (May-Jul) in C and N Europe connect to W, SW Europe Aug-Oct; W, S Africa Oct-Jan. Fewer C European breeders to Black Sea Aug-Sep, M East, E Africa in Oct-Apr (imm. Jun-Jul). E European breeders (Jun-Jul) connect to S Africa Nov-Mar, few M East, E Africa Jan-May. Passage Mar-May and Aug-Oct in SW Europe connects to NW, W, C and N Europe in Jun-Jul, local breeders Jun-Jul to S America (from Azores) and W Africa mainly in Jan. Connections from ‘other regions’ best reveal full wintering range and extent to which immature birds remain there May-Aug.

Grey Heron is widely distributed throughout much of the Old World, in Europe, Africa and Asia, but absent in the boreal region and deserts(BirdLife International 2021). Migratory behaviour varies from resident to partial migrant or migratory (Voisin 1991) with a cline of increasing migration to the N and E.

Connectivité globale pour Héron cendré

Movement patterns vary from ‘local’ dispersal of up to some hundreds of km to true migrations, of up to >6000 km (though most movements <2000 km). Migration is more common N and E populations, even also at more regional levels (Manikowska-Slepowronska et al. 2018). Overall, migration takes places along a NE-SW axis, up to N Africa and the Sahelian belt in W Africa, up to Tchad and Congo Republic. Populations from E and C Europe winter from C and W Europe to N and W Africa; some kind of parallel migration patterns, especially seen in Africa, to a lesser extent in Europe (Campos et al. 2001). N European Grey Herons overwinter mostly from the British Isles to C and W Europe, with some birds found in N and W Africa. Wintering in Iceland has also been reported, particularly of birds ringed in Norway. Birds from the British Isles and W/SW Europe are geerally resident (Campos et al. 2001, Wernham et al. 2002), but with some NE-SW movements as far as Africa. Recoveries in SC/SE Europe are mostly due to the C-European population which migrate on a N-S axis.

Contrôles par Condition for Héron cendré

Currently, around half of the recoveries are of birds seen alive and identified from leg ring(s) or other marks. Before 1960, a remarkable proportion of recoveries were of shot birds (>45%). During 1961-1990, this source of recoveries fell to 26%, though most birds were still found dead. Currently, 44% of the birds are found dead or sick/wounded, with far fewer shot birds (<5%).

Annual Movements for Héron cendré

Post-natal/-breeding dispersal/migration seems to start as early as Jul, when recoveries in Africa not due to summering birds are found. The bulk of migration is detected, however, from late Aug to Oct. Return to breeding grounds seen from Feb, up to Apr. In May, virtually all birds at their breeding sites, except subadult non-breeders, that can remain in their wintering areas or somewhere between these and their future breeding grounds. Recoveries in W Africa exceptional from late Apr onwards.

Connectivité par mois par région pour Héron cendré

Excluding resident birds, most European populations seem to have a similar migration pattern, with first movements in Jul-Aug, following a NE-SW axis, so giving rise to some degree of connectivity, although with high overlap in W/SW Europe and in W Africa, where birds coming from W to C and E Europe overwinter together (Zwarts et al. 2009). Migration from the wintering areas starts in Feb but mostly occurs in Mar-Apr in N European birds. By May, all birds are on their breeding grounds, unless they are non-breeders. Summering in W Africa has been reported, especially for the C and N populations.

Medium-sized passerine, feeds on seeds, berries, and (in summer) invertebrates, especially Lepidoptera larvae and beetles (Coleoptera); in winter quarters specializes in beechnuts Fagus sylvatica. Breeds across boreal and subarctic zones of west Palearctic, in the more open birch Betula woods, and in mixed forests of birch and conifers. Winters in Europe from S Sweden to N Morocco and from UK to Turkey and Georgia. The population trend appears to be decreasing, but not sufficiently rapid to approach the thresholds for Vulnerable. A medium distance migrant. Extent of movement is strongly dependent on food availability; local concentrations of millions of birds occur in south-central Europe.

Predominant direction of movement of Fennoscandian birds is NE - SW, with many connections with the Low countries, but also UK, C and S Europe. From the UK, movements are predominantly NW - SE, with connections with the Low countries, S and SE Europe. Birds from W Europe move mainly in NE - SW direction with connections with SW Europe and one in N Africa. Also movements in NW - SE directions with connections with C, S and SE Europe and one in Georgia. Birds from E Europe move mainly in NE - SW direction; most connections with C Europe but also with W and SW Europe. C Europe has connections with Georgia.

Until 1987 annual number of encounters fluctuated around 700, only 1976 was much better with 1531 encounters. After 1987 six years followed with lower numbers between 158 and 531. From 1994 to 2002 numbers increased to the same level as before 1987. After 2002 average numbers  increased to around 2000, but with big fluctuations between 672 (2007) and 4005 (2006).
Most encounters are in January, then the numbers decrease gradually from February to May. In fall the peak is between 8 October and 7 November, followed by a second peak in December.
Before 1960 about 38% of recoveries were dead birds, between 1960 and 1990 this percentage was still relatively high with 30%. After 1990 about 3% concerned dead birds.

Annual Movements for Pinson du Nord

In Nov - Dec the hotspots are in the Low Countries and N Italy. Other encounters are spread over S Fennoscandia, UK, SW and C Europe and around the Black Sea. In Jan the hotspot in N Italy is gone and concentrations appear in S and SW France, Switzerland, and UK. In Feb only the hotspots in Switzerland and the Low Countries remain, few birds in S Europe and N Africa. In Mar - Apr birds move north, few birds left in France and C Europe. Birds move to Fennoscandia but still many birds in Low Countries and UK. In May most birds arrived in their breeding areas. From May - Aug few birds stay in the Low Countries, C Europe and N Italy. In Sep the first migrants arrive in UK, W and S Europe. In Oct birds have left N Fennoscandia and the hotspots in the Low Countries and N Italy build up.

Birds from Fennoscandia are found in Lithuania in October and from October - March in the UK and W and S Europe. From January - March there are recoveries in Slovakia, Hungary, Croatia and Georgia. In September a bird was reported in Iceland. Birds ringed in the UK were found in Ireland, the Low Countries, France, N Italy and N Spain from October - March. Eastern Europan birds are reported in the Low Countries, Germany, Switzerland, France and N Italy from October - March. From December - February there are recoveries in Hongary and Czechia. Birds from W Europe are found in Iberia from November - March and in February in Morocco and Malta. Other birds moved to N Italy and were reported from August - February and more easterly in Romania, Bulgary and Georgia from December - March.

Connectivité globale pour Panure à moustaches

There are thousands of ring re-encounters further than 50 km from the ringing site, though most of them obtained within a few hundred kilometres, also few up to 900 km. So the bearded tit is clearly a dispersive species (Axell 1966), with sometimes some movements at longer distances, along a classical north-east to south-west direction, though tits hardly move from one region to another. There are however some movements between the British Isles and the continent, or between southern Fennoscandia and Central Europe (Horˇák et al. 2003).

Contrôles par Condition for Panure à moustaches

The few old recoveries were of dead birds, but post 1960, and even more recent data concern almost only live recoveries, with most data obtained in the 2000s.

Annual Movements for Panure à moustaches

The movements attested by long-distance ring recoveries are probably dependant on particular resource or meteorological conditions, explaining the unusual dispersion of some birds in some years at unusual distances.

Connectivité par mois par région pour Panure à moustaches

Most long-distance recoveries have been obtained in November, December and January, more rarely at the end of October, with no geographical pattern among the different regions in Europe.
