Shrikes of the World (Helm Identification Guides)

Product Information

The subspecies homeyeri (sometimes known as ‘Steppe Shrike’) breeds from south-east Europe through the Ural mountains into western Siberia. With a new series of stunningly detailed plates showing the full range of variation within species, and text accounts that incorporate recent advances in genetic work, the wait for the second edition has surely been worth it. The identification of badius depends on the absence or virtual absence of visible white in the base of the primaries on the closed wing of adults. Willow Tit comprises fourteen subspecies but only three are of relevance here – kleinschmidti (‘British Willow Tit’) from Britain, borealis (‘Northern Willow Tit’) from Scandinavia, Denmark, the Baltic States, European Russia and Ukraine and rhenanus (‘Central European Willow Tit’) breeding on the near-continent east to westernmost Germany and north-west Switzerland. The species accounts give information about the past and current distribution, along with threats and conservation status.

The plates in Shrikes of the World are a joy to behold and feel like a real celebration of this diverse and attractive family. I had the good fortune to be in Nigeria while reviewing this book, where there are two resident species of shrike that were completely unfamiliar to me; Yellow-billed Shrike and Emin’s Shrike. For shrikes closer to home, the teasing apart of the various subspecies and forms of Great Grey Shrike did much to help me to understand this complex species group. 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.Barn Owl comprises around thirty-five subspecies across its large world range but only two are of relevance here – nominate alba from Britain, western and southern France, Iberia and the western Mediterranean and guttata (‘Dark-breasted Barn Owl’) eastwards from the Netherlands across central Europe and western Russia. The most endangered shrike species in the world is the Newton's Fiscal, a black-and-yellow bird found only on a single island, Sao Tome, which sits on the equator off Africa's Atlantic coast. While my handy Helm Field Guide to the Birds of West Africa allowed me to quickly identify the two species, Shrikes of the World gave an invaluable deeper level of understanding, allowing me to interpret the behaviour of a family group of Yellow-billed Shrikes and learn things about them that could only otherwise be gleaned from painstaking fieldwork rather than a simple birding outing.

And so, the publication of the latest in the Helm Identification Guides series will no doubt be of great interest to many. Today, these supremely effective predators thrive from the Arctic to the tropics, although in recent years, many populations have declined along with their habitats.Also examined here, all within the framework of an integral system of adaptation, are evolutionary trends affecting changes in bodysize and plumage coloration, foraging behavior, breeding dispersion, motor signal behavior and vocalizations. 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. This beautiful book represents the definitive account of shrikes and their relationships, appearance, conservation and lifestyle; it will be treasured by birdwatchers and professional ornithologists alike. The author, an exceptionally skilled observer and interpreter of bird behavior, has drawn on his immense experience of many hours spent watching shrikes in the field and has reared young shrikes in captivity.

A further five North Asian and Nearctic taxa are treated by IOC as a separate species – ‘Northern Shrike’. Special attention is paid to the devel opment of signal and communication behavior in groups of closely related species at different stages of their divergent evolution.The colour plates are simply spectacular, with the illustrations being almost photographic in their detail. Acceptance as cristatus/ mitratus/abadiei might be possible but a ringing recovery would be necessary to identify an individual to subspecies.

Birds showing some homeyeri characters have been noted in Yorkshire and Norfolk ( http://birdingfrontiers.Miocene diversification of an open‐habitat predatorial passerine radiation, the shrikes (Aves: Passeriformes: Laniidae)" (PDF). in size; however, the genus Corvinella, with its extremely elongated tail-feathers, may reach up to 50cm (20in) in length. Most of our PDFs are also available to download and we're working on making the final remaining ones downloadable now. The subspecies pekinensis is not on the British List although it is a potential vagrant and has occasionally been suspected (Kehoe 2006).
