MDOspreys, Interesting! Thanks for the research on the tides. One could make the case that at the high tide (null), very little in the way of Loon-chow is being swept out of the creek. Note that the sightings are all just inside the narrow inlet between the creek and the bay. It could be that the Loon feeds out in the bay or down stream when the tide is moving out. Yesterday I scanned the bay and found only one Loon sleeping. It was a Common. At Oswego, NY the juvenile Yellow-billed Loon spent a lot of time feeding outside the breakwater separating the river mouth from Lake Ontario. It would occasionally come into the river and make a tour around the harbor then go back out into the lake. I don't know what that means other than that it may have preferred the deeper water of the lake but found something to its liking in the river from time to time. Perhaps the deeper water of the bay is this bird's preferred habitat. I wish I knew something about the habits of Yellow- billed Loons. Anybody have any ideas?
