Woodchat Shrike occurs in warm, open or semi-open areas, breeding in various mosaic habitats, interspersed with low and high herbaceous and shrubby vegetation, as well as scattered trees (Harris & Frankiln 2000). Its distribution is largely restricted to Mediterranean Europe, NW and N Africa, Caucasus and E to Iran, with some scattered populations in C Europe (Cramp & Perrins 1993). European strongholds of the species are located in the Iberian and Balkan Peninsulas (Keller et al. 2020). It is a European-African migrant, wintering in sub-Saharan Africa N of the equator (mostly the Sahel zone).

Connectivité globale pour Pie-grièche à tête rousse

Birds breeding on the Iberian Peninsula are encountered during migration (primarily spring) in NW Africa – mainly Morocco, but also Algeria and Tunisia. C European breeders take mostly SW routes, to W & SW Europe, mostly in autumn. Older data suggest a possible migratory divide in C Europe (Germany). In the 1930s, several juveniles from extirpated populations in N & E Germany and NW Poland migrated SE to Aegean Greece in their first autumn. Long-distance recoveries from the sub-Saharan winter quarters are scarce – a bird ringed in Nigeria and found in Italy (Spina & Volponi 2006) and a bird from Germany found in Sudan. The SC European population (Italy) migrates roughly N-S, mainly to Morocco and NE Algeria.

Contrôles par Condition for Pie-grièche à tête rousse

Most recoveries are after 2000 and are mainly during the breeding season and migration (85% in Apr-Aug) and mostly in SW Europe (~69%). The percentage of recoveries of dead birds has decreased from 75% pre-1961 to 3% after 1991; those of live birds increased from 17% before 1961 to 96% after 1991. Shooting was an important factor in the past - 29% pre-1961 and 18% in 1961-90. Nowadays, the majority of recoveries are recaptures by ringers. Shrikes are among the numerous birds illegally trapped and killed annually in the Mediterranean (Brochet et al. 2016). Most distant (>=50 km) recoveries are located around the C & W Mediterranean, there are very few long-distance recoveries of Е populations (nominate ssp. and niloticus).

Annual Movements for Pie-grièche à tête rousse

Pre-migratory movements start in Jun (Harris & Frankiln 2000) and migration Jul-Aug; adults leaving first (Cramp & Perrins 1993). SW European breeders are in NW Africa (Morocco, Algeria & Tunisia) in both autumn (Sep-Nov) and (mostly) spring (Mar-May). C European populations migrate mainly SW, with encounters in France, the Iberian Peninsula and NW Africa mostly in Aug-Sep, very few from Oct-Nov. There is a recovery from the Sahel wintering grounds (Sudan) in Oct. Return migration starts Feb (rarely Jan), peaking in Mar-Apr. Spring migration through the W Mediterranean and NW Africa is from mid-Mar to the end of May (mostly early April to mid-May), the nominate race migrating about 13 days later than ssp. badius (Gargallo et al. 2011). Breeding grounds are usually occupied in Apr-May.

Connectivité par mois par région pour Pie-grièche à tête rousse

Post-breeding dispersal happens mid- to late summer with most birds having left breeding sites in early autumn. The Spanish population is found from Morocco to Tunisia in early to late autumn and early to late spring. The German population was intensively studied in the 1950-60s, resulting in encounters mainly in late summer and early autumn in W & SW Europe and NW Africa (rarely in mid- or even late autumn). Birds breeding in SC Europe are encountered mostly in early to late spring in N Africa. Spring migration usually starts in late winter, it is more pronounced in early to mid-spring, and some of the breeding grounds are reached in late spring. Some W populations possibly make a loop migration, with their spring recoveries being further E than autumn recoveries (Yosef & ISWG 2020).
