The 83 species featured in this book, in date sequence of discovery, had not been recorded in Britain or Ireland before 1946. The original accounts of the sightings published in issues of British Birds* between 1947 and 1982 are now reprinted and supplemented with comment by Dr Sharrock on subsequent occurrences and current status. In addition, Peter Grant provides identification notes drawing attention to points not covered in the original accounts. There is also a world distribution map for each species and a line illustration to head each of the accounts. At the end of the book a section of plates reproduces 81 'first-sighting' photographs covering 32 of the species in the book.
