1 Species no. 32: Rock Partridge Alectoris graeca Distribution: This European endemic partridge inhabits both low-altitude rocky steppes and mountainous open heaths and grasslands. It occurs in the Alps, the central and southern Apennines, Sicily and the Balkan Peninsula. Movements: It is sedentary, but is known to make some local movements between high altitude summer quarters and lower altitude wintering quarters. Population size and trends: The European breeding population numbers 40,000-78,000 pairs with the largest population in Italy and Greece (BirdLife Int. 2004A). The EU 27 population is estimated at 20,000-38,000 pairs (BirdLife Int. 2004A, 2004B). Although certain populations-notably sizeable ones in the Former Yugoslav Republic of Macedonia and Greece were stable or increased during , the same species continued to decline across most of its European range and underwent a moderate decline (>10%) overall (BirdLife Int. 2004A). The main cause of decline in mountain areas is probably the loss, and change, of prime habitat associated with decreasing rural low-intensity activities. The development of the tourist industry has also led to habitat destruction and, by opening up remote areas, increased disturbance during the breeding season. In Mediterranean regions, the decline seems due to increased human impact, especially poaching and intensive hunting. Biological and behavioural aspects: Breeding: clutch size is 8-14 eggs (6-21, highest numbers perhaps by 2 females); incubation: days; fledging period: capable of precocious flight at 7-10 days, independence of young c. 6 decades after hatching. Broods: 1 or 2, clutches sometimes laid a few days apart and second clutch incubated by the male. Reproduction & Prenuptial Migration * 205 *

In Sicily and low-altitude habitats in Greece it ends during the 3 rd decade of August. Reproduction & Prenuptial Migration * 208 *
5 Species no. 33: Red-legged Partridge Alectoris rufa Distribution: This European Union endemic partridge occurs in South Western Europe (France, Spain, Portugal, Corsica, northern Italy and Balearic Islands). While it has disappeared from Germany and northern France, it has been introduced successfully in England, Wales, Scotland, Madeira, the Azores and the Canary Islands. Movements: This is a sedentary species Population size and trends: The population of this partridge is very large (>2,000,000 pairs)(birdlife Int. 2004A). However, since the 1960s, the wild partridge stocks have declined throughout the range. The reasons for the decline include the intensification of agriculture (heavy pesticide use, mechanisation, irrigation, removal of hedges), the abandonment of farming in the hills and subsequent scrub encroachment and heavy shooting pressure exacerbated by the release of reared birds which encourages a level of exploitation that wild stocks cannot sustain. In many areas of Spain releases of hybrids threaten the genetic purity of wild stocks (EBCC Atlas of European Breeding Birds, 1997). The European populations have underwent a moderate overall decline (>10%) since 1970 (BirdLife Int. 2004A). Biological and behavioural aspects: Breeding: clutch size: eggs (7-20); incubation: days; fledging period: capable of precocious flight at ca. 10 days; young birds are independent c. 6 decades after hatching. Young birds stay with parents through out the first winter. Broods: 1 or 2 simultaneous broods. Reproduction & Prenuptial Migration * 209 *

9 Species no. 34: Barbary Partridge Alectoris barbara Distribution: This partridge is mainly a bird of North Africa, but it is also known from Sardinia, the Canary Islands and a tiny population in Gibraltar. Movements: This is a sedentary species. Population size and trends: The European/EU breeding population numbers 7,500-20,000 pairs of which 5,000-10,000 breed in Italy and 2,500-10,000 on the Canary Islands (BirdLife Int. 2004A). The trend for the Sardinian population is unknown (BirdLife Int. 2004A) Biological and behavioural aspects: Breeding: clutch size is eggs (8-18); incubation: probably c. 25 days; fledging period: presumably capable of precocious flight at 7-10 days. Young birds are independent c. 6 decades after hatching. Reproduction & Prenuptial Migration * 213 *

13 Species no. 35: Grey Partridge Perdix perdix Distribution: The Grey Partridge was originally a bird of the steppe, distributed from Central Europe to Mongolia. It has become adapted to arable land and has consequently been able to colonise most of Europe, from the Mediterranean regions to 65 N in Scandinavia. Movements: This is a sedentary species. Population size and trends: The European population numbers million pairs including 580, ,000 pairs in Russia (BirdLife Int. 2004A). The population in EU 27 is estimated at 840,000-1,900,000 pairs (BirdLife Int. 2004A, 2004B). The species increased in many countries in eastern Europe but decline in western Europe and overall the European population underwent a large decline during (BirdLife Int. 2004A). Changes in farming practices in recent decades have altered its habitat adversely. The traditional mosaic of mixed farming has disappeared or has declined severely in many countries, causing a reduction in abundance of insect prey for chicks, loss of nesting cover and increased predation. Large-scale releases for hunting purposes (e.g. in Belgium) results in genetic, demographic and sanitary problems. In some regions it is even on the verge of extinction, and two races have been included in Annex I. The race hispaniensis is restricted to the northern half of the Iberian Peninsula and the northern slopes of the Pyrenees (France). Its population is estimated at 2,000-6,000 breeding pairs in Spain, and is decreasing because of habitat changes, over-hunting and disturbance by tourism (Atlas de las Aves de España, 1997). The race italica is limited to central and southern Italy, where it is currently very rare and probably extinct or on the verge of extinction. Both the hispaniensis and the italica subspecies are included in Annex I of the Birds Directive. Biological and behavioural aspects: Breeding: clutch size: eggs (4-29, often stated that clutches of c. 24 or more from 2 females but this certainly not always so); incubation: days; fledging period: capable of precocious flight at ca. 15 days; independence of young birds at c. 6 decades; broods: 1.

17 Species no. 36: Common Quail Coturnix coturnix Distribution: Western Eurasia, Northern India, North Africa, Southern and Eastern Africa, Madagascar, Comoro Islands and Mascarenes. In the Palearctic, the species has a wide breeding distribution across temperate Europe, Western Asia and Northern Africa. The main wintering areas are in Africa south of the Sahel and in India. About 10-25% of its global range occurs in Europe, where it is widespread south of 60 N. Movements: The European population is highly migratory with most of the birds moving to Africa in winter, though small number remains in Southern Europe. The long distance migrant population decrease, whilst the number of birds wintering north of the Sahel has increased. The return migration to the breeding grounds in Europe occurs in late April early May. Population size and trends: The European breeding population of Quail is very large (2,800,000-4,700,000 pairs) and fluctuates, but underwent a large decline during , especially in central and eastern Europe (BirdLife int. 2004A). The EU 27 population numbers 810,000-1,540,000 pairs (BirdLife Int. 2004A, 2004B). Although the species increased in northern and central Europe during , declines continued in south-eastern Europe, and the total population size probably remains below the level that preceded its decline (BirdLife Int. 2004A). The large populations of France and Spain have appeared to be variable but stable. Biological and behavioural aspects: Breeding: clutch size: usually 8-13 eggs (7-18, more than 18 probably by 2 females); incubation: days; fledging period: c. 19 days, but can flutter off grounds at c. 11 days.

23 Species no. 37: Common pheasant Phasianus colchicus Distribution: The natural breeding distribution of this species extended from the Caucasus to Manchuria, Korea and Japan. It was introduced in Western Europe in Roman times, but in Greece it was perhaps already present as early as 1300 BC. It was introduced in many regions of Europe only at the end of last century or even at the beginning of the twentieth century. Movements: This is a sedentary species. Population size and trends: The European breeding population amounts to 3,400,000-4,700,000 pairs (BirdLife Int. 2004A). The population in EU 27 numbers 3,100,000 4,200,000 pairs (BirdLife Int. 2004A, 2004B). In northern Greece there is still a small population of nominate race colchicus which origin goes perhaps back to Antique times. It amounts to only a few hundreds of individuals (Handrinos & Akriotis, 1997). The European population declined in parts of north-central Europe during , while the key in the United Kingdom was stable or increasing. However, the status of the wild population is obscured by confusion with introduced birds. Regional densities vary according to the release of captive-bred birds. Biological and behavioural aspects: Incubation: days; fledging period: capable of precocious flight at ca. 12 days; broods remain with female for days before becoming independent; broods: 1.
