This morning, 3-29-2014, Eastern Bluebirds inspecting nesting box, in the meadows, off Green Way.  Saw 2 males.  

Seems like they are rare for Celery Farm, based on Rob Fanning's 2008 spreadsheet, and more typically seen in October and November.  

It is a LFP for me (lifetime first photo of species).

(Thanks for the report and photos, John!)
