Back at 1630, and I feel like an idiot! This
time I looked in and saw 5 frigging eggs. How
could I have missed it on Monday!!? Geez! At any
rate, the birds have apparently deepened the cavity since
last spring, because I could not reach the eggs. Anyway,
the 1980 nesting season has begun, a record early start.
