Maybe we also have to agree that observation must be made, for example, in a 25m x 25m (27,34yd x 27,34yd) area. Or what about Jos? |;|
Since you ask, I'd like about 800 m x 500 m +/- :-O
But actually, no big issue to me, my main observation area, where my feeders are and I do most of my observations from, is pretty much the size of a standard garden. And since garden birders count stuff from their gardens too, be it some raptor over a neighbouring mountain or waterbird down the valley, I am not sure if my area is really any bigger in terms of recording area than anyone else's. Just I can manage that area for the betterment of wildlife more effectively perhaps.
