Michael Kieron led 7 participants on a walk of the Nature Conservancy's Lime Rock Preserve which has some unique features, soils and interesting history. Michael, a life long Rhode Islander and curator for the Roger Williams Park Natural History Museum, is a geologist as well as birder and knows a lot of local history about many parts of the state. So, in addition to having a pleasant bird walk, including watching a flicker excavating a nesting cavity, we learned a great deal from Michael about the geology and history of the preserve while we walked. The alkaline soils of the area make it the preserve a site for rare flowers that will bloom during the months of June and July inviting a visit during the summer, as well as later in May when migrant birds have arrived.
