I revisited the site of the Goose nest yesterday afternoon to get some shots in better light. As I was waiting, hoping the goose might move into a better position, I noticed this sign. My tripod and bag can be seen in the background.
Below is one of the shots of the nest, taken with my 400 5.6 and 1.4X extender. I'll keep trying for a better pose, until the reeds grow up and block the shot.
