I was at Sandy Hook on Saturday 3/24, first time I've been there. I read about North Pond, but by the time I got up that far I was distracted by Fort McHenry, and didnt make it there. I bet the sunlight angle is better there for viewing and id'ing in the afternoon too. Oh well next time!
I use ebird too and have contributed 100 checklists, and 60 species photos, 178 species seen. Frankly yes I check the county hotspots of where I'm going and compare them before I go, but they only help a little because my ID skills arent solid and there are still alot of species I'm missing on any given day. One day I hope to be at your level!
