We have been birding on and off for a little more than 20 years. When we lived in NYC we went birding with groups organized by the Audubon to Central Park and Jamaica Bay. Other places include Arizona, northern Mexico, southern France, Newfoundland. We had bird guides for most of these trips. Here in Philadelphia, we have been to the John Heinz Refuge and Fairmount Park. We have always enjoyed adding new birds to our life list and meeting others who are like minded.
