A monthly guide of where to go birding in the Delaware Valley Birding Region
We are blessed to have so many outstanding locations within a 90 mile radius or two hour drive of Philadelphia – this area being loosely known as the Delaware Valley. Immediately, National Wildlife Refuges sites such as Edwin Forsythe aka Brigantine, Bombay Hook and John Heinz aka Tinicum come to mind, not to mention the whole Cape May area; numerous forests, preserves, state and county parks; reservoirs, rivers, bays and coastal marshes and sandy beaches; hawk and sea watches; nature centers and nature parks along with a plethora of other smaller patches that are highly desirable birding spots.
This BIRDING BY MONTH section provides suggestions on particular birding location during certain months, should you want to go out birding or to look for a certain target species. While a number of these sites could be birded with success at almost any time of year, we have made an effort not to repeat ourselves too often and in certain cases just mentioned what a particular location has to offer at that time of year.
