Key concepts of Article 7(4): Version 2008 Reproduction & Prenuptial Migration * 405 * Species no. 68: Turtle dove Streptopelia turtur Distribution : The species breeds in Europe, western Asia, the Middle East and North Africa, with isolated populations (subspecies rufecens and hoggara) in Egypt and southern Sahara. The range in Europe covers most of the continent north to 60° N. Movements : Migratory throughout Europe, with all birds wintering in the northern Afrotropics. Population size and trends : The European population numbers 3.5 – 7.2 million pairs (BirdLife Int. 2004A) of which 1.6 – 2.7 million breed in EU 27 (BirdLife Int. 2004B). In the past populations have tended to fluctuate, however since 1970 declines occurred in up to 60% of the countries for which trends are known. During 1990-2000 most populations continued to decline (BirdLife Int. 2004A). Biological and behavioural aspects : clutch size is usually 1-2 eggs; incubation: 13-14 (-16) days; fledging period: ca 20 days; independence: soon after fledging; broods: 2-3 broods, but probably only one brood in the northern populations.

Species no. 69: Skylark Alauda arvensis Distribution: This lark is very widespread and inhabits a major part of Europe and Asia. It is breeding in all regions of the European Union. Originally a bird of the steppes or similar open habitats, it has become adapted to agricultural habitats and most birds now breed on farmland. Movements: The species is wholly migratory in the North and the East of the breeding range although in the South and the West the birds are mainly residents. The birds of northern and eastern Europe (including birds coming as far East as 50° E) leave their breeding areas and move to south-west in a broad front across Europe to winter mainly in Ireland, Britain, Benelux, western and southern France, Iberia and Italy. Population size: Its European breeding population is estimated at 40 – 80 million pairs including the large Russian population of 15 – 35 million pairs (BirdLife Int. 2004A). The EU 27 population has been estimated at 18 – 35 million (BirdLife Int. 2004A, 2004B). While the eastern populations appear stable most western populations declined during 1990 – 2000 (BirdLife Int. 2004A). Biological and behavioural aspects: clutch size is usually 3-5 eggs (7); incubation: 11 days; semi-nidicolous; fledging period: c. 18-20 days, but young usually leave nest at 8-10 days; independence: become independent at 25 days from hatching; broods: regular up to 4, but fewer in northern range.

BG HR FR - main period of reproduction is 1st April - 31st July, but young birds may still be found in the nests in August Comments and conclusions 1) In most countries, where resident and migratory birds are mixed, the period of

reproduction begins with the construction of the nest. In other countries where it is mainly migratory, the reproduction period begins with the occupation of breeding sites.

2) The end of the period of reproduction ranges from the 3rd decade of June (BG) to the 3rd decade of August (CZ, UK, SI, PL). The full flight of young birds (c. 3 decades after hatching) marks the end of the period of reproduction.

IT - the analysis of a large set of ringing data indicates that return movements start in February, peaking in the middle of March. Comments and conclusions

1) Breeding birds are entirely migratory in north and east of the breeding range, and partially (local movements) in south and west.

2) Beginning of prenuptial migration difficult to identify due to the mixing of resident and wintering birds, and lack of studies on wintering populations and counts of migrating birds.

3) Arrival of first migrants or departure from wintering grounds corresponds to the beginning of the prenuptial migration.

Species no. 70: Blackbird Turdus merula Distribution: This thrush inhabits Europe, North-Western Africa and further east through Turkey to southern China. The European population constitutes more than 50% of the global population and in Europe it is only absent from northern Fennoscandia. Movements: In southern and western Europe the species is sedentary, but the birds of the north and the east are migratory and winter in the south-west. Population size and trends: The total population in Europe is estimated at 40 - 82 million (BirdLife 2004A). The population in EU 27 numbers 33 – 69 million (BirdLife Int. 2004A, 2004B). Originally a bird of dense forest, this species has become well adapted to man-made habitats and urban areas since the last century. The population was stable in 1970-1990 and slightly increasing during 1990-2000 (BirdLife Int. 2004A). Biological and behavioural aspects: clutch size is usually 3-5 eggs (2-6), varies within season (smallest clutches at beginning and end); incubation: 12-14 days; fledging period: average 14 (10-19) days; independence: three weeks after hatching; broods: 2-3 are regular, except in northern range where 3 are rare.

Species no. 71: Fieldfare Turdus pilaris Distribution: This thrush inhabits a major part of Eurasia, from central Europe and Scandinavia to eastern Siberia. It is originally a species of the taiga, which has considerably extended its breeding area to the west, and even colonised Iceland. Movements: Most birds are migratory and winter in western, central and southern Europe. Population size and trends: The total European population is estimated between 14 and 24 million pairs of which 10 – 15 breeds in Russia (BirdLife Int. 2004A). The population in the EU 27 Member States is estimated at 2.4 – 4.8 million (BirdLife Int. 2004B). The Fieldfare has expanded its range strongly south-westwards since the 1800s. In the early 19th century its distribution reached NE Poland and by the turn of century, Germany, the Czech Republic and Austria. Expansion slowed, incorporating only Switzerland up to 1950, then accelerated to Slovakia, Denmark, Belgium, E-C France, N Italy and Romania (1960s), The Netherlands, Great Britain, SE France, Slovenia and Hungary (1970s) and Greece (1980s). Expansion continues westwards, southwards and within the C European range. Population size has increased in most European countries during 1970-1990, and in Luxembourg, Italy, Slovenia, Hungary and Romania by more than 50% numerical increases which accompanied considerable range extensions; the French breeding range increased by 400% between 1970-75 and 1985-89. In Fennoscandia the population size is stable but fluctuating and the overall trend for Europe during 1990-2000 in Europe is stable or increasing (BirdLife Int. 2004A). Biological and behavioural aspects: clutch size is usually 5-6 eggs (3-7); incubation: 10-13 days; fledging period: 12-15 days; independence: app. 30 days after hatching; broods: 1-2.

IT - the return movements as indicated by the analysis of ringing data, start and peak in January, and are already over by the end of February. Comments and conclusions 1) Largely migratory. Winters mainly in western, central, and southern Europe. 2) Identification of the beginning of the prenuptial migration is difficult where

wintering and passage birds mix with resident ones, and data on the variation of wintering numbers is deficient (FR, AT).

3) In western, central, and southern Europe, departure of first migrants corresponds to the beginning of the prenuptial migration.

4) Beginning of prenuptial migration ranges from the 2nd decade of January (IT) to the 3rd decade of March (LV).

Species no. 72: Song Thrush Turdus philomelos Distribution: This thrush inhabits a major part of Europe and northern part of Asia eastward to Lake Baikal. In Europe it is distributed from the Pyrenees and the British Isles to northern Scandinavia and Finland. Movements: The populations of southern and western Europe are sedentary. Those of the north and the east are migratory and winter in the south and west of the continent. Some migratory birds reach North Africa. Population size and trends: The European population numbers 20 – 36 million including the large Russian population of 6 – 10 million (BirdLife Int. 2004A). The breeding population of EU 27 is between 10.8 and 21.0 pairs (BirdLife Int. 2004A, 2004B). The population was mostly stable during 1970-1990 but decreasing in Germany during 1990-2000 (BirdLife Int. 2004A). This was compensated by increases in France and Norway and overall the European population has remained stable during 1990-2000 (BirdLife Int. 2004). Biological and behavioural aspects: clutch size is usually 3-5 eggs (2-6); incubation: 13 (10-17) days; fledging period: 13 (11-17) days; independence: becomes independent shortly after fledging; broods: 2-3, but not more than two in northern range.

Comments and conclusions 1) In Northern, Central, and Eastern Europe (where it is mainly migratory), the

reproduction period begins with the occupation of the breeding sites. In Southern and Western Europe (where it is resident or dispersive), the reproduction period begins with the construction of the nest.

2) The end of the period of reproduction ranges from the 1st decade of July (ES) to the 2nd decade of September (UK). Full flight of young birds marks the end of the reproduction period.

Species no. 73: Redwing Turdus iliacus Distribution: The Redwing has a widespread breeding distribution in the boreal region of the Eurasian taiga. It also inhabits sub-arctic and alpine regions. Movements: Almost the entire world population winters in western and southern Europe and around the Mediterranean and the Black Sea. A smaller part of the population winters south of the Caspian Sea. Population size and trends: The total population of Europe is estimated to 16 – 21 million pairs including the large Russian population of 12 – 15 million pairs (BirdLife Int. 2004A) The population breeding in EU 27 numbers 2.4 – 4.3 million pairs (BirdLife Int. 2004B). The European population has been stable during 1990-2000 (BirdLife Int. 2004A) but may fluctuate according to severity of the weather conditions in winter. Biological and behavioural aspects: clutch size is usually 4-6 eggs (3-7); incubation: 12-13 days; fledging period: 9-13 days; independence: 14 days after fledging; broods: two broods are normal, but only one in northern and alpine Scandinavia.

1) In the EU, the Redwing only breeds regularly in SE, FI, EE, LV, LT, PL and UK. In southern EU where it is hunted, it does not breed.

2) The period of reproduction starts with the occupation of breeding sites. 3) The end of the period of reproduction ranges from the 3rd decade of July (EE,

UK, PL) to 3rd decade of August (LV). Full flight of young birds marks the end of the reproduction period.

1) Migratory or partially migratory. Iceland and Faroese populations winter in the UK (Scotland), IE, Western FR, ES and PT. British and mainland Eurasian population winter in western Europe, south-east of Baltic area, and around Mediterranean, Black and Caspian Sea.

2) Nocturnal migration, although easy to recognise for this species, and discrete behaviour makes it difficult to identify the beginning of the prenuptial migration.

3) Departure of first migrants indicates the beginning of the prenuptial migration. 4) The beginning of the prenuptial migration ranges from the 3rd decade of

January in the south (ES, IT) to the 3rd decade of March in the north (FI, EE, SE, DK).
