Clearly this update hasn’t been fully tested, something all computer science student are taught to do when developing an app. Author and illustrator Norman Arlott is one of the world's leading bird artists and has seen nearly all of the 1,800 species featured. It covers more than 250 species, which are illustrated with superb full-colour artworks that show - where relevant - variations in plumage, for example for male, female and juvenile birds, and breeding and non-breeding birds. Its level of detail is unprecedented for a book of this size, and it will be sought after by all bird enthusiasts.

Most especially, we have worked hard to make it simple to follow by using inspiring narratives, key ID points and high quality artwork and photography. It, like many others, ignores the wild, free-flying Spanish population reintroduced to the south of the country.

A unique spotter's guide for the first-time birdwatcher It is not always easy for the amateur birdwatcher to correctly identify a bird from the glimpse that is seen as it flies past, but you do notice and remember the bird's colour. Like any book, it's not without typos – and the one worth noting is that the species introductions on waders and gulls are on pages 136-137 and 182-183 and not as stated in the text. The forums are dedicated to wild birds, birding, binoculars and equipment and all that goes with it. This book covers difficult identification issues by looking at tricky species pairs or groups of birds, and comparing and contrasting their respective features.

From the perspective of the British birder, updates to some of the terns, swifts, Old World flycatchers and finches are among the most relevant.

Und nicht zuletzt wurden Artenportraits neu abgegrenzter Unterarten von Polarbirkenzeisig und Birkenzeisig aufgenommen.
