On May 12, at the height of spring migration before tree canopies are in full leaf, SMAS marked World Migratory Bird Day with its tradition of birding around Spangler's Spring on Gettysburg National Military Park. During the first half-hour, chapter members saw more than 25 species - and I picked up three bits of information. At the close of the count, all those eyes had seen 65 species, including 13 kinds of warblers. One of the joys of birding is that there always is more to see and learn.
