The identification of pinetorum is problematic. Not only is it not a distinctive subspecies but it also intergrades widely with nominate major. Biometrics are useful, however, pinetorum being long and slim-billed and short-winged. Identification of nominate columbarius can be straightforward by reference to the tail pattern. The subspecies pallidus is strikingly pale and finely marked. Garner, M. 2002. Identification and vagrancy of American Merlins in Europe. Birding World 15: 468-480. Glutz von Blotzheim, U.

Shrikes of the World (Helm Identification Guides) - Goodreads

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 MitchellClaims of ‘classic’ guttata are welcomed if accompanied by detailed notes and preferably photographs. Details of a ringed or marked bird would provide additional evidence.

Claims of pekinensis are welcomed if accompanied by detailed notes and good photographs but only a ringing recovery from the core range is likely to confirm this subspecies in a vagrant context. ( updated Dec 2017 AMS). 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.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.
