Marshall, 1945 17 Feb Wedge Lake GPO #244 Marianas Large black duck or small goose like Black Brant seen over marshes (several night before). Two swallows, white below, throat & tail black and apparently a white spot within the black anterior area, forked tail, in flight just over treetops edge lake. ? I don't think it was a "swallow-tail" like Barn swallows just graduated. A new shore bird totally brown above except for pure white below except for black throat & art chest. Still large (30) flocks of Golden Plovers "Thrasher"
