Hmm... If you're thinking globally, this is going to be hard. A simple checklist of all the bird species of the world is large enough to be a book, literally.
And, it's outdated at the time it's printed.
The Sibley Guide to Bird Life and Behavior might be what you're looking for, if North America is enough of the world. Embarrassingly, I own this and almost never look at it.
The Sibley Guide to the Birds of North America is a good desk reference field guide that has more information than most field guides (and is too big to carry around other than as an app on my cell phone, IMHO). I do own it both ways. The book is better, of course. But, I don't carry it as my field guide.
For more than that, you may want to pick a book narrowed down to a particular family of birds, if she has any favorites like raptors or woodpeckers.
Hope you find what you're looking for.
