Shrikes of the World (Helm Identification Guides)

Product Information

American Bird Conservancy and our Joint Venture partners have improved conservation management on 6.4 million acres of U.S. bird habitat — an area larger than the state of Maryland — over the last ten years. This is a monumental undertaking, requiring the support of many, and you can help by making a gift today. Claims of minor should be accompanied by biometrics. Details of a ringed bird would of course provide additional evidence. ( updated Dec 2017 AMS). Identification is not always clear-cut. There is considerable individual and sex-related variation in both subspecies whilst intergradation between alba and guttata means that only darker guttata (predominantly females) are safely diagnosable and paler guttata may be overlooked. The key features are uniformly deep buff underparts extending to the tarsi, undertail coverts and underwing coverts, extensive dark grey hues in the upperparts and dark areas around the eyes (French 2009). a b c Yosef, Reuven (2008).

Details of any birds outside Scotland are welcomed. Acceptance as cristatus/ mitratus/abadiei might be possible but a ringing recovery would be necessary to identify an individual to subspecies.

The taxonomy of the ‘Great Grey Shrikes’ is in a state of considerable flux and at least six potential species have been identified though not formally proposed (Olsson et al. 2010). Pending further work, IOC currently defines Great Grey Shrike as comprising twelve subspecies, of which ten inhabit North Africa, the Middle East and Central Asia and have been treated by many authors as ‘Southern Grey Shrike’. A further five North Asian and Nearctic taxa are treated by IOC as a separate species – ‘Northern Shrike’. The subspecies calidus is not straightforward to identify as there is extensive character overlap with nominate peregrinus. Juveniles offer perhaps the best prospects, though only the palest birds will prove striking in the field. Separating the two Arctic subspecies is also problematic and categorisation as calidus/ tundrius (‘Arctic Peregrine’) might be the most appropriate treatment. Potential identification problems also include the elimination of other large falcon species, especially escaped birds from falconers/collections whose genetic make-up might be obscure. Biometrics are helpful, calidus being large compared to nominate peregrinus. The subspecies homeyeri (sometimes known as ‘Steppe Shrike’) breeds from south-east Europe through the Ural mountains into western Siberia. It is not on the British List but it has occurred in Sweden, Germany and Finland. Birds showing some homeyeri characters have been noted in Yorkshire and Norfolk ( http://birdingfrontiers.com/2010/12/15/sheffields-steppe-shrike-update/, Nash 2012). However, neither of these individuals showed the full suite of characters.

The subspecies pallidirostris (usually referred to as ‘Steppe Grey Shrike’) breeds in Central Asia. It is a rare but regular vagrant to Britain with 26 records to the end of 2017. Key features include a rather bulbous bill, long legs, long primary projection, pale lores, weak face mask, pinkish hues in the underparts, dusty brown hues in the pale grey upperparts and a large white wing patch which is restricted to the primaries.

Dutch Birding 36: 365-393. The subspecies kleinschmidti is a declining breeder in Britain. Otherwise only borealis is on the British List with two accepted records (in Gloucestershire in March 1907 and in Yorkshire in February 1975). The 1907 record was reviewed by BOURC in 2009 and remains accepted (BOURC 38 th Report). There are a number of other British claims (e.g. Brown & Grice 2005) but they appear not to have been submitted to BBRC despite a request for records ( British Birds 77:123). The subspecies rhenanus is said to be largely sedentary and is probably an unlikely vagrant.

Shrikes: A Guide to the Shrikes of the World - Lefranc Shrikes: A Guide to the Shrikes of the World - Lefranc

The "true" shrikes are a striking group of birds occurring throughout most of the Old World and North America. This is a comprehensive guide to 31 species of shrike from all over the world. It includes information on distribution, general behaviour, ecology and conservation, as well as on identification features. The author covers the latest taxonomic views on the family, and considers the Southern grey shrike to be a separate species from the great grey shrike.Identification of nominate columbarius can be straightforward by reference to the tail pattern. The subspecies pallidus is strikingly pale and finely marked.

Many borealis are readily diagnosable on the basis of greyer upperparts, whiter cheeks and underparts and, in fresh plumage, a stronger white midwing panel but worn kleinschmidti pose a potential pitfall. Biometrics might also provide useful evidence.This is a second edition of Norbert Lefranc's Shrikes, fully updated from its 1997 predecessor. The introductory texts have been significantly expanded and six new sections have been added in the species accounts: vagrancy, foraging behaviour, breeding success, population trends, conservation and taxonomic notes. Special attention has been given to the latest developments in shrike systematics, not forgotten by the DNA revolution. Glutz von Blotzheim, U. N. & Bauer, K. M. 1993.

Vangidae, vangas, helmetshrikes, woodshrikes, flycatcher-shrikes, shrike-flycatchers and philentomas The family name, and that of the largest genus, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as butcherbirds because of the habit, particularly of males, of impaling prey onto plant spines within their territories. These larders have multiple functions, attracting females and serving as food stores. [1] The common English name shrike is from Old English scrīc, alluding to the shrike's shriek-like call.

Shrikes ( / ʃ r aɪ k/) are passerine birds of the family Laniidae. The family is composed of 34 species in two genera.
