I birded the Milwaukee Lakefront this morning and the highlight was gulls. 1 Gluacous Gull juvenile at Bradford Beach. Other gulls were a Glaucous Gull adult and 2 Great Black-blacked Gulls adults near the petroleum pier on broken ice or on the pier itself. It was a cloudy day with stiff winds making it feel like a cold January day. Images were taken on February 24, 2016.
