19 May NKE Lonee Man's Fae Club, West W
Weighed these young ones again about 1800 hrs.
Only one legged, the youngest. One other gaped
once. The rest crunched. Once or twice one
gave a note - it seems to be either a
single note or an extremely rapid series,
probably the first. It sounds more like a
food begging note than a fear note, but
the one that gave it wasn't begging. It
may be a "hurt" note, and I may have
been pressing its leg. Primary sheaths
on the little one are out about 5 mm., on
the others about 12 mm. The larger ones
have their feathers almost out, on the
wings, and broken through on other
parts of the body. They are more
active in the weighing book than the
white crowns. The little one's eyes
are barely open, and he keeps them closed
whereas the others are kept wide open.
20 May Visited nest + weighed about 1730 hrs.
Primaries still not out of sheaths, but
on older birds, back + flank feathers are
out. Only youngest bird (no mark) legged
today. None are as active in my hand
as previously. Notes given while I am
at nest do not seem to alarm parents. But
a great weight increase today.
21 May Weighed about 1715. No gaping, all
crunched and was still. Only gave sounds once.
Doesn't sound like White Crowns. Feathers well out
of sheaths, esp. on back. Little one still legs.
All active in hand, burrowed into each.
