The book should be available at a much cheaper price directly from the publisher: http://www.edizionibelvedere.it/novi...taly-2-english
I say 'should' because the order procedure seems to be quite clunky. After completing the order form, you are supposed to get an email with the amount due and a paypal link, but I have not received it yet. Also, make sure you click on "accept cookies" otherwise you won't be able to send the order form.
Volume 1 is very good, and I expect Vol. 2 will also be. One minor criticism is that many dubious or obviously wrong published records are accepted: a couple of examples from Vol 1 include a spring record of 6 Upland Sandpipers together, and sight reports of Rough-legged Buzzards from late Aug/Sept that I am sure are all juvenile Honey Buzzards. Part of the problem is that for any given species, the Italian RC only reviews the first 10 post-1950 records (it used to be the first five), and that there is some resistance within the committee to re-visit older records, so that purging mistakes from the literature is a process that takes time.
Anyway, Italy deserves a lot more attention from foreign birders, there may not be any endemics (unless you split Sicilian Rock Partridge) but the birding is excellent!
