Baltimore Oriole Icterus galbula
Lord Baltimore in his manor: I often see this bird in Mulberries, as if he has claimed this tree for their own. Robins and Catbirds may disagree, but there will be plenty of fruit to go around when it ripens. Another good thing about the Oriole-Mulberry connection is that it will sometimes bring the treetop loving bird down closer to the ground and to reasonable angles for a portrait.
