jimmy,it,s only guess work this one but its down to numbers,and how you want to crunch em,if 21 birders look at 1 piece of water then there going see everything available,and not miss the artic terns etc,if 1 birder looks at 5 ponds they might miss the odd gem.but back to food thing, all the flashes waters contain the same ratio of fish/gallon/food/acereage/watchers it,s down to pie r squard and squarin ther circle cheers geoff
just asking but is there a reason that arctic terns favour pennington and not wigan flashes is it because of food or is wigan flashes off the arctic terns migration route and pennington is or is it another reason jimmy
