Merganser... going going gone!

On Sunday 20th October, I walked over to the Boulevard from the Wherry and could see the Red- breasted Merganser, the eclipse or immature male was very, very close on the water just a few feet away, it really was very close, but as I was setting my camera up it started raining (I could see Danny P already taking pics) and a lady walked to the edge and this spooked the Merganser which swam very quickly away and to the middle of the Broad and then subsequently dived and I didn't see it again. No pictures and this was very, very frustrating to say the least!!
