This is great news at last something might be done to halt the devastation that these birds are doing to our fish.Any dead goosander is a bonus and with each one killed hundreds of fish will be saved.But why stop in May(maybe because it is the breeding season)and anything is better than nothing,in Winter when the rivers in Iceland,Norway,Finland and Russia ect are frozen over we in the U.K see an increase of these birds by four fold so if there is a limit to the amount of birds that can be culled by doing it in the Winter there is only a 1 in 4 chance that a bird killed will be a resident which because they are here all year round will eat twice as many fish as a 6 month winter visitor,but they all eat fish so each one counts.
