Maked Duck, Coots in Gorgona

Alfred Raab visited the fresh water pond near the ocean in Gorgona yesterday evening and found ten American Coots and a female Masked Duck.
Turn left at Gorgona, which is after the large meadow on the right of the Pan-Am highway.
Keep going straight for a few km's. Then you come a fork, take the left branch (it is almost straight). After the large (bankrupt?) development you will see the large pond on your left. The female masked duck was on the far side across the lake in the marsh. You need a good scope to see it.
