When submitting eBird observations at Great Meadow, it is most helpful to start a new checklist for each hotspot in the area. Use the general hotspot when you have a checklist that includes multiple locations or if no other hotspot or personal location is appropriate for your sightings.

If you carefully keep your bird records by state, be aware of the location of the state line and use the appropriate eBird hotspots when you submit checklists.
