A new site has been added to the left sidebar under Birding Sites. After searching for maps similar to the one I developed yesterday I came across a very nice implementation of a birding related Google Map API.
The map is draggable and zoomable. There's an additional feature to search for birds using drop down lists. The bird chosen will filter the markers to those featuring the bird in question.
Clicking on any of the map markers will display the name of the location with an option to link to additional site details with driving directions.
