Today scattered individuals present. Also
flock of 8♂+9♀ (112♂, 4%) were noted. In
addition, group 12-6♂ were also noted. More
added to the confusion, a few plot birds
Sometimes it was difficult to separate
breeding females from non-breeding or
non-settled birds. In creches - there were
so many ♂ - it was impossible to tell who
was who. A brooding ♂ was less different -
usually the postern end is sticking out
into the air over lower the chest. In
posture - The bird does not waddle more.
Also, brooding bird will never fly off
a nest + gives call note at nest area first,
until she has moved a certain distance
from the nest. - It is just the opposite
with non-settled birds. Also the last
would take flight & so out (light -
frustrating, after cooing one for 15 min -
waiting for her to go back to the nest!).
Also, the female nest & I think more often
when they have chicks - gives a different
call note - in addition to the regular
♀ call note. One is a rolled rather
quilted trill - which is strikingly similar
to the vocalization of a tundra - [illegible]
