You also seem to have some rather docile birds. I can never get as close as you do.
I´m not sure you would say that if you joined me on a trip. It often takes me a couple of hours of very careful movements and lots of sit-still-and-be-patient time to get them close enough. Some duck species are easy though
The other day I spotted an Eurasian Teal, which is rather rare this far north. It was too far away, but I thought he would come my way, so I sat patiently in a spot, very quiet and still. After a long time I heard a low whisper next to me and I had a giant male swan studying med from 4-5 feet away, with his head and wings held in their aggressive posture and I was sitting on my but, with the tripod and 600mm over my lap. You don´t mess with them! First instinct was to run, second was to sit still, which i did. After a while he lost interest and glided away. Puuhhh! An hour later I could conclude that I would not get an image of the Eurasian Teal ...
