Northern or temperate species such as the great grey and red-backed shrikes are migratory and winter well south of the breeding range. The sexes of most species are distinguishable, the male invariably being the brighter bird where there is a difference. There are some natural groupings within the genus, such as the seven African fiscals, the large grey species (''ludovicianus'', ''excubitor'', ''meridionalis'' and ''sphenocercus'') and the Eurasian brown-backed species (''tigrinus'', ''bucephalus'', ''collurio'', ''isabellinus'', ''cristatus'' and ''gubernator'').
