Could you make it iBird Europe, rather than UK? (or Western Palearctic)? Anyway, once you had UK you're nearly all the way there...
I live in Norway, and bird around Europe. Am sure you must get numerous requests for a Europe version, and great numbers of people would buy it. I see there is a string on this, though no responses yet.
I got iBird Pro simply for the info I could find on North American species that show up here; and in case I get to NA one of these days...
Could you get iBird Pro to use your current location in the search routine? Perhaps you could add Europe and other locations in among the States and Provinces so we can limit a search among species that occur here? Or allow us to add a personalized search criteria? (such as from a Notes field: if we wrote in the species that occur in Europe or some such place, we could search for that)... Anyway, an iBird Europe would be a great hit.
BTW, there are 2 typos in the Flickr help window... (addtional and sceintific)...
