Geographical variation – what races are recognised, where are they found and how do they differ; e.g. does the race balearica only occur in the Balearics?
So, this isn’t just another set of information – it’s THE text covering what is known about each species. Most of this information is timeless but, of course, details of population sizes and trends will eventually change. However, BWPi also contains all the text from the Concise Edition of BWP, a further 1697 pages, so the population figures are updated at least to 1998. Altogether there are approximately six million words of text in BWPi 2.0. THE ULTIMATE ARTWORK Some of the plates in the original BWP were criticised for not being up to the rigorous standard of the text so no fewer than 230 new plates were prepared for the Concise Edition. BWPi will include all the plates from Concise BWP. That’s over 5600 detailed illustrations of over 900 species – about 50% more illustrations than in the Collins Bird Guide. The average of over 6 paintings per species indicates just how many plumages are represented here, including many that simply are not illustrated anywhere else. With artwork by
