I hope this is a Spotted Sandpiper? (I'm trying to learn them but I have a ways to go yet.)

I don't want to list them on eBird till I'm fairly sure that I'm reporting the correct bird! (This one, and a probable Solitary) were at Arkendo Park in Oakville this week. There are also European Fire Ants along the mud flats which was not pleasant to discover.
