18 Apr. Bear Wen's Far Club, Nest Z - I'm sitting on bridge (N-S) hidden partly from nest by tree. Adults are not approaching nest.
They go into broadleaved plant about 3 ft.
from nest but unless they are adventurous

Later - I am convinced they are visiting
nest quite frequently, coming up from
underneath after about a 2 ft
