Retrieved 23 July 2023. The species accounts give information about the past and current distribution, along with threats and conservation status. Detailed and fully revised maps accompany the authoritative text, along with hundreds of high-quality photos showcasing racial and ageing differences as well as interesting aspects of shrike behaviour. An exceptional new series of plates by Tim Worfolk have been created, with more individual plumages shown than in the previous edition. Shrikes are territorial, and these territories are defended from other pairs. In migratory species, a breeding territory is defended in the breeding grounds and a smaller feeding territory is established during migration and in the wintering grounds. [7] Where several species of shrikes exist together, competition for territories can be intense. And so, the publication of the latest in the Helm Identification Guides series will no doubt be of great interest to many. Shrikes of the World, by French ornithologist Norbert Lefranc and acclaimed artist Tim Worfolk, is in fact a fully updated version of Shrikes, their seminal work published in 1997. A subspecies unique to California's Channel Islands, the San Clemente Loggerhead Shrike, has been listed under the Endangered Species Act since 1977 and has been the subject of intensive management, including predator control and captive breeding.

The identification of ‘classic’ homeyeri rests largely on the amount of white in the secondaries and spread tail but is hampered by the significant individual, age and sex-related and geographical variation both within this subspecies and within excubitor. Two broad plumage types of the latter are recognised – a darker morph with white restricted to the primaries (most prevalent in the northern part of the range and formerly given the name ‘ melanopterus’) and a paler morph with white extending onto the secondaries (most prevalent in France and Germany and forrmerly given the name ‘ galliae’). This latter type may approach homeyeri in appearance, as, might excubitor/ homeyeri intergrades.

Claims of ‘classic’ guttata are welcomed if accompanied by detailed notes and preferably photographs. Details of a ringed or marked bird would provide additional evidence. 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. The subspecies britannicus is very common in Britain. The status of nominate ater in Britain is, however, somewhat obscure but its occurrence here has been confirmed by ringing recoveries (Wernham et al. 2002). It is perhaps best regarded as a scarce, irruptive migrant and may even have bred on Scilly in the late 1970s (Kehoe 2006, Parkin & Knox 2010). The subspecies hibernicus is presumably a potential vagrant.

A Guide to the Shrikes of the World

This long-awaited update to the acclaimed first edition is the definitive guide to a complex and intriguing family. The species accounts and taxonomic treatments have been fully revised in line with recent studies, and the all-new plates and photos complete this remarkable work. Highly recommended.' - Dominic Mitchell The booke of falconrie or hawking: for the onely delight and pleasure of all noblemen and gentlemen: collected out of the best authors, aswell Italians as Frenchmen, and some English practises withall concerning falconrie: Turberville, George, 1540?-1610?". Internet Archive. 2023-03-25. p.73. Their predatory habits, which will often see them take large insects or, in many cases, small birds or mammals only amplifies their uniqueness among passerines, while a penchant for choosing exposed perches from where to sit and survey their territories makes them generally easy to observe and study.

And although the Northern Shrike is doing well for now, its Arctic range is vulnerable to climate change, and this species could lose more than three-quarters of its habitat if global temperatures rise by 1.5°C. The plates in Shrikes of the World are a joy to behold and feel like a real celebration of this diverse and attractive family. From the fiscals of sub-Saharan Africa to the Northern Shrikes of high-latitude Siberia and North America, the quality of illustrations is superb throughout. The variations of spread wings and tails in the 'grey shrike' taxa will surely hold plenty of interest for European birders. Yosef, Reuven; Pinshow, Berry (1989).

About the contributors

Forsman, D. 2016. Flight Identification of the Raptors of Europe, North Africa and the Middle East. Bloomsbury, London. 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). Shrikes are a charismatic group of small- to medium-sized birds with striking raptor-hooked bills and a face mask that gives them the look of small, fierce highwaymen. Their Latin name, Lanius, means butcher, and shrikes are commonly known as "butcher-birds" for their habit of impaling insect prey on the thorns of bushes. This book is the first complete guide to the thirty-one species in three genera of the family Laniidae. Along with superb illustrations and range maps to facilitate successful field identification of all the shrike species, this useful book contains the most recent information on the entire shrike family. Identification to subspecies is difficult though cristatus is paler and more ‘grey and white’ than scoticus. The subspecies mitratus is more similar to Scottish birds. However, mitratus intergrades extensively with cristatus, producing birds of variable appearance.
