I was just wondering if this current situation might provide a unique opportunity to get data, relevent to the suggestion that inner City pollution has been a major factor in the huge drop in House Sparrow numbers?
There will hopefully, never be another situation like this but with the huge drop in airborne pollutants, there will never be a better time to test the hypothesis?
