I saw a peep sandpiper in Southern Ontario on the muddy shoreline of a small river on June 18 and 19, 2021. I'm confused about the ID because they are so similar. I know it's not a Least Sandpiper, it was larger than they are and has black legs. The upper breast appeared quite spotted, very obvious the second day I saw it. I have a few photos of it.
Can anyone tell me which species it is?
