If you are thinking of something that is resident, there aren't that many choices. House sparrow and starling are out as they are Eurasian species. Northern cardinal and blue jay are fails on colour. So you are left with American robin (still too colourful?), black-capped chickadee as common birds. Less common ones could include house wren, chipping sparrow, eastern wood-pewee, downy woodpecker, or white-breasted nuthatch. Adding in migrants would give more choices, but less time frame, only May and June. Examples here could include yellow-rumped warbler, Swainson's thrush, eastern phoebe.
For me, American robin really is the dominant loud singer of residential areas.
