FIELD NOTES
Doug Bell
DATE: JUNE 4, 1985
LOCATION: EAST SAND ISLAND, NORTH (COLUMBIA RIVER,
(BAKER BAY), OREGON.
Up about 8:00 AM - it rained all night and continues to
drizzle a bit. Some intermittent clearing. Spent late morning
surveying area around camp and the eastern end of island.
Checking for gull nests and possible trap sites. In the
area just west of camp - natural sandy soil covered in short
gresses and drift wood - an area about 1/2 size of a football field,
found following nests:
# Eggs Present No. of Nests
0 8
1 3
2 4
3 30
In eastern dredge-spill area, and on beach, found following:
# Eggs Present # of Nests
0 0
1 0
2 1
3 6
13:00 - onwards.
Setting out traps. Weather has turned sunny. One
trap on beach pair near gear, one trap on 3-egg nest
in spill-dredge area. No luck though. I would check one
trap, then the other. Each time my approach would be
announced by all birds in area. Gulls had either time to
walk out of trap before I got to it. Tried trapping
in area just west of camp. This worked better - could
hide and "rush" trap. Caught a male gull ([#948 018]) at
about 16:00. Could not tell what type of mate it had.
This bird died while wrapped and waiting for processing.
Left the beach trap out, and the trap over
the nest of 018. Am trying to catch its mate. Waited till
