A year and half ago, I wrote my "Bird Watcher" column about Marc Chelemer of Tenafly, who had been birding for 1,000 days in a row.
Marc just wrote to me that yesterday marked a birding milestone: 
" I visited the Great Swamp in between my regular full-time job and my afternoon teaching job for a 35 minute visit along Pleasant Plains Road. The resident Barred Owl was the highlight, though a continuing burly White-crowned Sparrow at the Helen Fenske Visitor Center feeders was also nice. The checklist marked 1,500 days in a row…"
Congrats, Marc. That's some serious birding.
