to go. All egg shell remains were gone.
It started over to side as I caught
it. Too slipped R3 and weighed,
17.45gms. Young R2 also captured
swimming away from the nest but not
weighed. At 10:55 a.m. egg #4 with
an active "in hewing" young set it but
nowhere pipped thru, weighs 24.91gms.
still cold in the 3 egg nest at 15.14.
This nest is 6 in across the cup, which
is about 2 in deep- water to rim opposite
gangway is 6 mi - rim to rim from
gangway is 11 in. Composed of
Dry broad leaf cat-tail- level with
fined cat tail shreds-gangway is
poorly constructed, really more, just a
place for one. Nest faces SW- open
water being 3 ft away in that direction.
No immediate overhead canopy, but
the broad leaved cat-tails around the
nest form an effective cover about
5 feet up, so the nest is really
effectively concealed from above.
