"Iceland Gull/Thayer's Gull intergrade" (adult) - Hammond Marina, Lake County, Indiana - January, 2015

This interesting adult bird shows many characteristics of both Thayer's and Kumlien's Iceland Gulls. We see many gulls on Lake Michigan that, like this bird, appear to be intermediates (intergrades) between Thayer's and Iceland.

These photos were taken with a Canon 60D Digital Camera with a 100-400mm zoom lens.
