Frolic melanotos
7 July Barrow, Alaska
Flock of 48? in area of polygon + boots -
NE1 magnetic station + Bead Ridge.
Another group of 12 encountered on B.R. -
east 1 magnetic station. 3 & 4 included
in our group - were not being persecuted
by the 877 - all were feeding actively.
The 877 & were collected.
FEEDING BEHAVIOR - Three 877 feeding halfway
down the north slope of B.R. were watched feeding -
& this was recorded on the feeding sheet.
Nearly all feeding action was pecking at the
surface of the ground +/- at the vegetation
[Calabrica ridge slope - thickly covered
with 3-4" grass sedge]. Virtually, no probing
was noted - the birds would sweep slowly,
pecking to both sides - sometimes the head
would be lowered - as if to peck & then jerk
up - it indicated that whatever was seen - was not food item - just
had moved. - Sept seems to play
a good part in food selection. In
this. This lowering of the head - gives a bobbing appearance
to the head.
8 July Flock of 10 at curved Bead Ridge -
Cobble ward & between slopes West Wohlleb
[illegible] - all 877 - No aggression, no displays.
