In reply to sheelba:
If you've ever dreamed of seeing vultures, head to the gorges du Tarn and especially gorges de la Jonte, you cannot not see at least some. There's spyglasses at the vulture museum with which you can see the birds nesting well above it. Watching them glide past as you climb is awesome (the Bitard is great for that). Quite a few dippers in the rivers too.
Pretty much any limestone cliff in the lower half of France there's a chance you'll see wallcreepers, even in Burgundy.
Ardèche, with the Col (pass) de l'Escrinet being one of the major migration highways in France.
Arctic Norway, especially the Lofoten and Vesteralen: godwits, sea eagles, kittiwakes, puffins, phalaropes and so on.
Iceland isn't really a climbing destination, but the number of birds (especially ducks, waders and seabirds) is truly dazzling!
(Not really a major birding location but I did find a hoopoe in my garden in Fontainebleau last summer!
