Birding this weekend at Institute Woods

   The Washington Crossing Audubon Society will conduct two field trips to the Institute for Advanced Study woods in Princeton. On Saturday at 8 a.m., a trip will be lead by Mark Witmer. On Sunday at 8 a.m., a trip will be lead by Lou Beck.
   The Institute Woods is an excellent place to observe spring bird migrations of warblers and other songbirds. Two dates are offered so that participants can pick the one more convenient for themselves. The Washington Crossing Audubon Society has nearly 1,500 members, mostly from the five counties of central New Jersey. Its monthly lectures and frequent field trips are free and open to the public.
   To reach the assembly site, take Alexander Street toward Route 1. At the bend in the road before the canal, turn right onto West Drive. Proceed a short distance on West Drive and park at the entrance to the Rogers Wildlife Refuge.
