Sadly, I have not had the chance to do bird hunting in the UK, it's definitely on my list and I have a standing invitation from a good friend of mine Kevin Downer, but time has not been on my side. I would love to do a few days of Grouse shooting with pointers, I heard so much about it and look forward to experiencing it myself.
I grew up doing driven Pheasant and Partridge hunting in France (among other things) and bird hunting is still my favorite; it never gets dull... I have had the opportunity to do many high volume bird hunts, and the ultimate for me, so far, is Red Partridge in Spain. My last trip, I hunted for three days and averaged 400 Partridge a day, needless to say I left with incredible memories and a sore shoulder.
Africa offers some amazing wing shooting as well, I am especially fond of Sandgrouse in Namibia since I have had a lot of opportunity to do that growing up. Just writing about it makes me wish I was there in the action. During the peak months, July through September, the Sandgrouse come in, like clock work, every morning at the same time, between 9 and 10 and for that hour it's non-stop action. On a great day, you can see over a thousand birds coming in to a small water hole during that time. About the size of a Dove, they come in at great speed to land at the edge of the waterhole, with a flight pattern similar to Ducks coming in to land on water... you can also hear them "wooshing" in overhead like Ducks.
Doves are right on up there in the action department and are a lot of fun too.
