I had to check the species data, "A", to see that the mallard in Portugal is the same as here. Nice image. Personally I would have shot in closer to her but I'm guessing you wanted to include the water and grasses since that's the reason for this series.
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
