visigoth:A second vote for a Mexican edition -- or simply an extension of the North American version. I know that most (all?) field guides seem to restrict "North America" to Canada and the US, but that's geographically just weird. And given the biodiversity down here, it makes sense to document it, if only to convince more birders to make the trip.
This could be done gradually, as additions to the current iBird. Any plans to do something like this?
I would love to add birds of Mexico but....there is no way to cost justify it. The illustrations would cost thousands of dollars and the app would sell in very tiny quantities.
Its a good idea and the only way I can see us doing it is if someone who has a book out now or has a ton of good photos approached me....
Insects is another one of those great ideas with too small a market to justify. Unless you already have all the contents.
