Diminishing returns

Three years' worth of vismig totals showing the declining returns, in line with declining hours, of vismig totals from Inverkeithing. There are various reasons for the decline in hours, but this year the easterlies meant the birds just weren't there - not even the seabird bonus you might expect from easterlies. I saw less than 10 skuas so far this year! Who knows how I will feel about it next year. Maybe a good start will invigorate my efforts. Hopefully there's still something to be seen this year before season close.
