I was just out at the Lagoon. I ran into Murray and we both saw a Baird's Sandpiper and I saw a Vesper Sparrow. I orginally ID as a Lapland Longspur. Looking at the field guides and my pictures I am certain that it is a Baird's Sandpiper. Here is the picture of the Baird's. It is at the western portion of the lagoon. The Horned Grebes were still out there. allin breeding plumage. I thought I saw some Red-necked Grebes but looking at the photos I took, they are definitley Horned Grebes.
Thanks for the confirmation Watchmen and Gord! As I was looking through my pictures I noticed the legs were pink so I was flipping through my field guide at Longspurs then I was going to head onto sparrows. The Lapland Longspurs feet are black. It makes sense that it would be a Vesper Sparrow. I wonder if Murray got a different bird than me because he was ahead of me.
