May is the month of spring ephemerals and the return of multitudes of birds from the south. Riverstone Retreat is a haven for both of these. A variety of habitats from fields to forests to streams on the property play host to a wide diversity of birds and wildflowers. We will explore this rich biodiversity with leader Ernie Martin starting at 10am on Saturday morning. The walk is occasionally of moderate difficulty and will take about 2.5 hours. Bring a walking stick and water.
