The northern shrike was formally described by the French ornithologist Louis Pierre Vieillot in 1808 under its present binomial name Lanius borealis. [2] [3] In the 19th century, North American ornithologists considered it as a separate species from the great grey shrike, while European authorities held them to be the same species.
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.
The northern white-crowned shrike is a 19–23-cm long passerine. The adult has a white crown and rump, black eyestripe, brown back and wings and black tail. The throat, breast and belly are white, and the flanks are brown. The sexes are similar, but juveniles have a brown crown, white head sides, and grey breast. The flight is parrot-like.
The loggerhead shrike (Lanius ludovicianus) is a passerine bird in the family Laniidae. It is the only member of the shrike family endemic to North America ; the related northern shrike ( L. borealis ) occurs north of its range, however it is also found in Siberia.
The loggerhead shrike is hard to distinguish, but the proportion of the head to the beak (which seems stubby in L. ludovicianus by comparison and is all-dark) is usually reliable. Indeed, the word loggerhead refers to the relatively larger head of the southern species. [25] The lesser grey shrike is a smaller and comparatively short-tailed bird.
The shrikes vary in the extent of their ranges: some species, such as the great grey shrike, ranging across the Northern Hemisphere, while the São Tomé fiscal (or Newton's fiscal) is restricted to the island of São Tomé.
