The author defines more than 1100 words and terms in this illustrated dictionary for the birdwatcher.

Its attraction for the relative novice is obvious but it is equally directed to experienced birdwatchers who will find succinct definitions of terms that are new to them and of others that they have understood none too well.

Among the appendices is a full list of species on the British and Irish List arranged in 'Voous Order' and with categories of status in Britain and Ireland.

Whatever the user's ornithological expertise, the book will expand or confirm his or her knowledge and offer at the same time an absorbing and entertaining browse, as a good dictionary should.
