TWELVE MILE (MOFADDEN'S SWAMP) AT BRUCE, BENTON CO., ORE.
Weather: Cloudy with showers. Warm
Date: 14 Feb. 48 09:00 - 16:30.
List includes birds on north ponds and all that could be seen from
the road on the south pond.
Blue Heron - A couple around.
American Bittern - While eating lunch in the jeep on the road just east
of the Muddy Cr. bridge noticed something in the road which looked
like a paper sack that was open. Checked it with the binoculars
and found it to be a bittern standing still with neck pulled in.
A minute later it began walking very, very slowly and deliberately
back into the swamp. The movement was so slow that the bird's
camouflage was still effective even on the gravel. Eventually it
went back into the swamp, but several minutes later I noticed it
back in the road. This time it moved slowly toward the other side
with neck stretched almost to a complete horizontal position.
Just before it got back into the swamp, a car came along and at
the last moment the bittern awkwardly took to the air.
Canada Geese - Didn't notice any cacklers although there might have
been some. There was four to five thousand in all which moved
from the north swamp to the south swamp.
Mallard - [illegible] around 200
Baldpate - one male
Pintail - around 100.
Green-winged Teal - Probably 4,000 or more altogether. During the
morning for [illegible] some time the green-winged teal were kept in
the air by a female marsh hawk which kept making passes at them.
The passes were lazy like and the hawk appeared to be playing.
Shoveller - About 150. Sex ratio equaled.
Ruddy Duck - two or three.
Red-tail - one hung around Muddy Cr. during the morning.
Sparrow Hawk - two around the triangulation tower.
Ruffed Grouse - Flushed a ruffed grouse twice in the oak and ash along
Muddy Cr. It may have been the same bird both times.
Ring-necked Pheasant - 6 males and 11 females in the field just SE
of the triangulation tower. Flushed two males next to the duck
cabin. The two sexes stayed apart, that is the flocks did not
mix.
Coot - around 100.
Killdeer - one or two.
Wilson's Snipe - only one.
Flicker
Say's Phoebe - On a fence post west of the cabin. Seemed like Eastern
Oregon having this bird and the shrike in view at the same time
without even moving my binoculars.
Raven
Oregon Chickadee - one flock
Seattle Wren
Tule Wren
Robin
Varied Thrush - one in the ash.
Western Bluebird - scattered flocks.
Golden-crowned Kinglet - one flock in the ash along Muddy Cr.
Pipits - occasional individuals heard.
Shrike
Audubon Warbler - a few.
Red-wing - only a couple noticed in the morning.
Purple Finch
Oregon Towhee, Juncos, Song Sparrow
