Yesterday there were 2 Common Loons at Silver Lake (Lake Harbor), but today I could only find one, and he spent a lot of time under water. And when I got back to Esther Simplot Park, there were 3 Red-breasted Mergansers (males) swimming around on the back pond.
This is the pond that is furthest north and west and only has a dirt path around it. You can access it easily from the Greenbelt path or directly from Whitewater Boulevard.

Gotta love migration!
