Erolia Luciollis
2.
19 june Barrow, Alaska
They flew. The 8> lost again his
normal posture and bobbed his
head several times. No sound
was heard at this time.
1500.-1600. This pair was seen again
in the same general area. The courtship
display described above was seen once
again, but it was at such a distance
that nothing new can be added. The aerial
display was performed several times.
It was a typical erolia-type
display where the bird flew to
a height I about 31 feet
and then glided down giving
a high pitched twittering-note. This
note was a three-part tinkling
note which is very distinctive and
seems to be the highest pitched of
any 1 the Erolia's.
20 june Barrow, Alaska
The same birds as mentioned above
were watched for an hour and a half
(0930-1100) on the beach ridge. The
male was showing his territoriality
by making the rounds of approx.
10 acres on top the ridge. He would
sit on mounds at various locations
