Beetlebung Corner is really the center of Chilmark. The library, the school, the community center, the town hall, two banks, a restaurant, a general store, a real estate office and the post office are all within a few steps. This is all well and good for humans. However, for the birds Beetlebung Farm, which provides fresh vegetables and flowers in the summer, is their main attraction. By now the vegetables have been harvested and most of the flowers gone. Luckily there are still a few hardy nasturtiums blooming and a very late visitor arrived on Nov. 2 to enjoy the nectar of these nasturtiums. Marie Scott and Suzie Bunker, both daughters of Ozzie and Rena Fischer, spotted the hummingbird and alerted their father and their brother, Bert.
