I have not been out to Johnson Creek in Jefferson County lately so I gave it a try mid morning. There were a lot of gulls over the dump but only a couple hundred loafed at the Kohl’s outlot south of I94. It was nice to see 2 Glaucous Gulls in the small group there. There was 1- 1st cycle and 1- adult present. They took flight a few times as there must have been something in the area that spooked them. A very cold day with some wind but the sun made it feel not too bad. Images were taken on February 3, 2017.
