  "description": "Over the past month we have been blessed with Bald Headed Eagles flying around our home by the ocean.  Needless to say the Sea Gulls and Crows haven't been too pleased to have their feeding ground invaded!  \n\nOne day these 2 massive Eagles flew right above our decks . . . absolutely awesome!"
