Lettuce Lake Park - April 19, 2014

I wanted to stop briefly at Lettuce Lake this morning to see if there were any interesting warblers or other birds.  I saw the usual black and white warbler, carolina wren, cardinal, night heron, and some more unique warblers like parula and prothonotary.  However, it was actually some other living things: moss, lichens, and ferns, that caught my attention at the park today.
