Atkinson, Eric C. (1997). "Singing for Your Supper: Acoustical Luring of Avian Prey by Northern Shrikes". The Condor. Oxford University Press (OUP). 99 (1): 203–206. doi: 10.2307/1370239. ISSN 0010-5422. 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. 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 Crested Tit comprises seven subspecies, of which four are of possible relevance here. The subspecies scoticus occurs in north-central Scotland, nominate cristatus (‘Northern Crested Tit’) in Scandinavia, eastern Europe and Russia, mitratus (‘Central European Crested Tit’) in central and western Europe and abadiei in north-west France (Cramp et al. 1993). Merlin comprises nine subspecies, of which four are of most relevance here. In the Palearctic aesalon breeds across northern Europe to western Siberia, subaesalon in Iceland and pallidus (‘Steppe Merlin’) in northern Kazakhstan and south-west Siberia. In North America, nominate columbarius (‘Taiga Merlin’) breeds across the north of the continent. The splitting of Palearctic and Nearctic Merlins has been proposed.

Norbert Lefranc is a nature conservation officer at the Ministry of the Environment in Metz and is in charge of all nature conservation in Lorraine. Tim Worfolk is a leading bird illustrator whose work has been published in British Birds, Birding World, and Birdwatch. He is currently working on several other regional guides and identification guides to other bird families. 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 vocally imitate their prey to lure them for capture. [14] In 1575, this was noted by the English poet George Turberville. Harrop, A. H . J. 2004. The ‘North American’ Peregrine Falcon in Britain. A Review on behalf of the British Ornithologists’ Union Records Committee. Brit. Birds 97: 130-133. The subspecies aesalon is a regular breeder and winter visitor in Britain, subaesalon occurring as a migrant and in winter. An old pre-BBRC specimen record of nominate columbarius has been reviewed and rejected but the subspecies has now been readmitted to the British List on the basis of a bird in Caithness in February 2018 . There is also a record of this subspecies from Ireland in September 2000 ( http://www.irbc.ie/reports/irbr/2007_IRBR.pdf). The subspecies pallidus has also been claimed in Britain. Following the nitty-gritty of shrike relationships, there are general yet truly detailed accounts of the two shrike genera, filled with rich descriptions of their history, morphology, migration, habitat, and more, and includes a particularly enjoyable section on their food storage behaviour, with suitably gruesome illustrations. The colour plates are simply spectacular, with the illustrations being almost photographic in their detail. The species accounts follow a set structure and include high quality photographs of the birds in the field, with maps clearly showing the known range and where there are some uncertainties.Both nominate senator and badius are on the British List, the former a scarce migrant, the latter very rare with ten accepted records to date. The subspecies niloticus is not on the British List but is a potential vagrant. For the British birder, where every shrike species is sadly now at least a scarcity and some are extreme rarities, their allure is all the more intense. Each one tends to be a popular fixture, and their often-confident nature means they can be highly photogenic, as well as entertaining to watch. For example, many birders will point to the famous Steppe Grey Shrike in north Lincolnshire in November 2008, which used to perch on the gathered crowd’s cameras and telescopes, as one of their most memorable birding encounters on home shores.

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.

About the contributors

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. This book is the first monograph in English on the 34 shrike species distributed across Africa, Eurasia and North America. These birds have attracted the attention of ornithologists for a long time, mainly because of their predatory nature and the methods which they use to dispatch their prey. In the book, the most important information on shrikes of the World is summarized, much of which has accumulated in the ornithological literature and obtained by the author himself. These voluminous empirical data are also used by the author in an attempt to reconstruct the evolutionary history of the group at different stages of its phylogenesis, from the early origins of the family Laniidae, presumably in Africa, through the secondary expansion of species across Eurasia and into the New World.
