The Millersville Ornithology class has been witnessing the explosion in bird diversity with the arrival of Spring.  We have taken a number of trips to local filed sites to survey for birds.  The diversity of warblers, vireos and many other birds has kept the class busy looking up at the trees. Our last 3 class surveys have totaled near 70 species of birds.  Students have especially enjoyed the arrival of Indigo Buntings (picture below by Ed Schneider) and Baltimore Orioles.
