We know! We know!
Find the fish which are spawning and you will find hungry birds. At sunrise (5:30 am) there were an amazing number of loons, cormorants, mergansers and gulls at the mouth of the Lester River on Lake Superior. By 6:00 am the show was over, but I just shifted my location and hiked out to the Superior Entry. In the distance via my binoculars I had spied hundred of terns feeding. I said to my self: “Self … more smelt!”
It took a three mile hike but once out to the Superior Entry these rather “uncommon” Common Mergansers put on quite the show for me. This couple was much more concerned about catching fish than worrying about a human. Please note I advanced on the mergansers from out of the sun, and then sat down on the sand. Eventually the birds made their way over to me. One needs to have patience to get photographs like these images, and also not be standing up. Birds immediately recognize you as “a human” when you are standing tall. I was less than ten yards from the mergansers.
