i dont think it helps tony but i think the bigger problem is the old falcons they are released they maybe get two mins in the sky then a few falcons smash into the middle of them sending them running in the wrong direction then the conditions don't help as the bird is trying to navigate while distressed i often wonder when there a batch of birds maybe 2000 or 3000 birds and there heading in the wrong direction due to being frightened by a falcon how far do they go before they decide to turn around
