Alternative name: Iberian Grey Shrike
Includes: Steppe Grey Shrike

Identification

Length 24-25 cm, weight 50-70 g
A large grey shrike, very variable in the grey tones of the plumage (see further under Subspecies, below), though with fairly consistent pattern; much overlap in characters with Great Grey Shrike. Crown, mantle and rump grey; black 'mask' with or without a narrow white supercilium; inner scapulars usually white; wing black with small to large white patch at base of primaries; secondaries and tertials with small to large white tips; tail long, black-centred with white edges; underparts pinkish-grey, white, or dusky grey; bill black (pale-based in juveniles).

Taxonomy

L. m. pallidirostris

Isle of Man, July 2003

Complex, and much disputed. In the past, lumped in Great Grey Shrike, and some authors still treat many of the subspecies listed below in it[4]. L. m. pallidirostris from the steppes of central Asia is sometimes considered a full species called Steppe Grey Shrike[3].

Subspecies

Twelve subspecies (listed below) are currently recognised by the Clements list[1], eleven by HBW[2], ten by IOC[3], while Svensson et al. treat it as monotypic with all the other subspecies below included in Great Grey Shrike[4].

  • L. m. meridionalis: Iberian Grey Shrike
  • Upperparts dark grey, underparts pinkish-grey except for white throat
  • L. m. koenigi:
  • Upperparts dark grey, underparts light grey; similar to L. m. algeriensis but slightly smaller
  • L. m. algeriensis:
  • Upperparts dark grey, underparts light grey
  • L. m. elegans:
  • Northern Sahara (south of Atlas Mountains, also Mauritania to Sinai Peninsula and Red Sea)
  • Upperparts light grey, underparts white
  • L. m. leucopygos:
  • Southern Sahara (Mali to Nile River valley of the Sudan)
  • Upperparts very light grey, rump and underparts white
  • L. m. aucheri:
  • Upperparts mid grey, underparts white
  • L. m. theresae:
  • Upperparts dark grey, underparts white; similar to L. m. aucheri but slightly darker above
  • L. m. buryi:
  • Darkest subspecies; very dark grey mantle, dusky grey below, supercilium and scapulars grey, not white
  • L. m. uncinatus:
  • Similar to L. m. aucheri but with less white on scapulars, and slightly longer bill
  • L. m. jebelmarrae:
  • Intermediate between L. m. aucheri and L. m. leucopygos; included in L. m. leucopygos by HBW & IOC
  • L. m. lahtora:
  • Upperparts mid grey, underparts white; similar to L. m. aucheri but more extensive white on secondary tips, and black mask extends across top of bill
  • L. m. pallidirostris: Steppe Grey Shrike
  • Upperparts light grey, rump and underparts white; extensive white in wings; black mask narrow; bill often pale-based even in some adults (though black in many adults)

Habitat

Dry open country.

Behaviour

Behaviour is similar to other shrikes, using prominent perches and impaling corpses on thorns and barbed wire spikes.

Migration

Mostly resident or short-distance nomadic, but L. m. pallidirostris often migratory, many moving to northeast Africa as far south as Ethiopia and Somalia.

Diet

The diet includes large insects, small birds, rodents and lizards.
