An adult Black-headed Gull in basic plumage was discovered in Chicago on Friday, February 23 and was relocated on Wednesday, 2/28. It is still present. The bird is at Montrose Harbor, which can be reached by exiting the Kennedy Expressway at Irving Park Road. Take Irving Park to Lake Shore Drive, go N on Lake Shore Drive, and exit at Montrose east to the park. The bird has been seen in the harbor. Bring old bread to chum. It seems to appear quickly when bread is being tossed around.
