[Edit: Okay, everything seems to check out. Thanks Alan W. and Mike Bur. for confirming the ID - I'm a stranger to Eurasian shorebirds.]
I've been having some difficulty uploading images to Flickr and eBird so I thought I'd share some photos here.
The bird was feeding on a mudflat on Lake Huron in the community of Oliphant, at the T-intersection of Spry Lake Road and Shoreline
Oliphant is about 13 km west of Wiarton. Nearby were Greater Yellowlegs, an Hudsonian Godwit, Black-bellied Plovers, Dunlin and White-rumped Sandpipers.
What do you think?
Eurasian Dotterel and Dunlin.
