A female or possibly an immature male Yellow-headed Blackbird was seen Thursday about 11:00 AM at the Herrington Harbour Marina near Rose Haven, Anne Arundel County. Two others, besides myself, saw the bird which landed on a bare branch in a tall deciduous tree between the dinghy storage area and the slipholder parking lot which is accessed from the west entrance to the marina off Rt. 261. The bird resembled a Red-Winged in shape and size, was very dark, with no conspicuous markings, except for a yellow throat and upper breast. Paula Sullivan paulas@erols.com Alexandria, VA
