Reward points

My reward for counting almost 400 Mallards at Broom last night were these five spankers.  Blackwit has been a long-time coming on my SFYL this year.

  1. Just looked at the most recent population estimates in BB. The ratio for Mallards to Blackwits is 16.1:1
    The estimated wintering populations of Mallard is 710,000 and 44,000 for Blackwit. Obviously, this doesn't account for migrants. And also complete tosh, especially in Bedfordshire! It's more realistic to say 2000:1
