[edit] 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).

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].

[edit] 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)

[edit] Habitat

Dry open country.

[edit] Behaviour

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

[edit] 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.

[edit] Diet

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