My morning trips to Goose Lake have yet to produce the sandhills, but... I did see 1 fly over as I was driving in the entrance, so... at least, I know they are still here. Other producers include a few migrants:

A female Common Yellowthroat

The increasingly uncommon Henslow's Sparrow

A White-crowned Sparrow

A Palm Warbler

A Pied-billed grebe
