Ring-necked Duck

Shot this morning. Dark overcast as usual. I arrived to the lake and went to the section where 2 parts of the lake are connected with a narrow passage. I went down to the water level, tripod in the water and waited for 1/2 hour....nothing just a few Scaups way in the distance. I moved to the other side of the passage and there were more Scaups but too far again. These birds are super shy.
While I was waiting for the group of Scaups move closer..Osprey landed on the tree above me. It was facing direction to the other side of the passage were I was earlier. 
10 minutes later huge splash and I am looking to my right there is Osprey lifting nice size  trout out of water. I didn't even had a chance to take the shot. 
If I would stay at my first location I could more likely get a super nice shot of the Osprey with the fish.
Later on few Scaups came closer, but still a good amount distance.
This male Scaup was keeping eyes on me.
