This is an update of a field guide that I have used for many years. It is now slimmer and lighter but has not lost any of it's detail. In fact there are many improvements including comparitive charts of difficult to distinguish species. I love the illustrations and find them easier to use and compare than photographs. The distribution charts are clear and aid identification. We have all seen a bird outside it's normal range but this feaure is useful as a first step in identifying that unknown bird. Highly recommended.
I find this field guide very useful, and well laid out, although it could prove a little heavy to carry all day in your pocket, but no doubt you will have a rucksack to ease the burden! It has all the information that you will need to identify the birds you are most likely to see in Britain and Europe, and some others too! My only criticism of this particular book is that 4 pages have been "Double Printed" Which makes it difficult to read. I would strongly recommend that before purchasing, that you see a copy to check the quality of the printing.
I bought this for friends as I had an older version of the same bird book - the reason it's so good: - 1. Great size - large enough to have good pictures but small enough to carry around 2. Detail - amazing amount of detail 3. Similar species - if you aren't sure about a particular sighting of a bird the book gives you similar species.
