Erolia fuscicollis
9 june Barrow, Alaska
was watched during the entire afternoon.
Most of the time was spent in feeding, but
one bird was seen to give a courtship
display force. The posture here is as

head held a bit higher - or at least
so higher at one suspension - when the
call is given. The note seems to be more
it - zha-porns, zha-poring,...
given with quite a
violent movement.
The head up & down.
They paid no attention.
The displaying bird would fly just a
short aerial hill - each time upon
landing - the wing (1 wing) would be
held vertically for a second or so
then be folded slowly into proctu -
almost in a deliberate (or ceremonial)
manner. He was seen at least 10 times.
Once - the bird landed about 40' from
the other white rump wheel was feeder
near 2 Rerlin. After the display landed
he apparently evos alarmed & raised me
away toward those other birds - The lower
raised it again - 3-4 times. Suddenly -
then started to fly & hovered over this
