Bird-watchers of a feather flock together. Are you interested in warblers, tanagers or flycatchers? Well, you’re in luck; join BirdPhilly for a Friday morning of bird watching in peak migration season in Haddington Woods in Cobbs Creek Park. Don’t worry: These city birds have an edge to them, but are still cute. Binoculars available. Meet on the northwest corner of 63rd and Market streets
