The N♀ working S along H, feeding a young, is arousing the interest (15:35)
of one of the S pair. A moment earlier the S was in E/S area again,
and met a young coming out, billing it before diving for food for it.
The male moved back into his territory
from H 14, bringing 2 young with him.
A short time later one of the S pair was
in the same area w/♂ young. - The N♀
was in K20 with 2 young. Lots of
algae on the surface of the open water
there, and a snake or turtle scared
the young into the cat tails at L20.24.
The ♀ moved over, killed each of the
young and took off after their tormentors - she swam rapidly,
in a zig-zag course, pecking at
the water, as if trying to catch a
rapidly moving snake swimming
on erratic course just under the
water surface. After twenty or so
feet she lost it. A short time later
the ♀ moving north with 2, a 3rd
from north boat and 2 with the ♂
means 5 as in the brood - a little
while later the one parent + all 5
young were feeding at L27 - at least
4 young diving or tipping for food,
and some feeding (or rubbing?) one
another. Except for one small one, the
N brood seems quite independent of their
parents - during this same time
