May 6th - 12mile Swamp, continued:
found April 2 that "keyed" out to this species was completely torn up when
we checked it today. It could be that Redwing competition tore up this
nest. Just a theory, for there is a pair of them here, even if we didn't
see them on Apr. 22nd. This pair will have a hard time getting a foothold
at this swamp, because of the large number of redwings present. We found
over 20 nests without hardly covering the biggest part of the swamp. If
the Yellow-heads nest, it will be at the very edge of the swamp, for it is
quite unlikely that they will be able to "stake out" a territory within
the swamp proper.
Redwings - all paired up, it seems, and plenty of them. The following nests found:
1. 3 young and 2 eggs in Carex obnupta clump at 18". Large set.
2. 4 eggs at 2 1/2 feet in Ash tree or bush
3. 4 eggs at 3 1/2 feet in Spirea
4. 1 young and 3 eggs just hatched at 1 1/2 feet in dead ash. Open site.
5. 4 eggs in Carex at 2 feet
6. 4 young in Carex at 1 1/2 feet
7. 1 nest vacated already. No young seen today
8. 1 nest at 12" in Eleocharis
9. 1 nest at 15" in "
10. 1 nest at 13" in "
11. 3 eggs in Carex at 18"
12. 3 young and 1 egg in Carex at 24". Pin feathers developing.
13-18 - 6 new nests in Carex at from 2 to 3 feet.
19. 3 eggs at 28" in Carex
20. 4 eggs at 30" in Carex
21. 4 eggs at 3 feet in Cattail
22. new nest at 2 feet in Carex
23. new nest at 2 feet in Carex
24. 4 eggs at 5 1/2 feet in Spirea, sheltered
25. 3 eggs at 1 1/2 feet in Spirea
Purple Finch - a pair in the gravel road thru the swamp
Song Sparrows - singing here and there.
May 8, 1947 - S Spur, Mac Donald Forest, N of Corvallis, 1330-1700, Ovc, Rain, windy.
Blue Grouse - hooting continually - 2 different birds
Band-tailed Pigeons - cooing-like, and in flight.
Flicker - a pair of them
Coast Jay - one pair seen, and same or others heard frequently the rest of the time.
Gray Jay - saw just one of them in the fir woods
Ravens - a pair of them flew over.
Yellow Warbler
Lutescent Warbler
Black-throated Gray Warbler
EVENING GRASS BEARS - 2 - Small flocks still around the campus, but a great deal less than before.
May 9, 1947, N. Cemetery Hill, 1 - 115 p.m. Sctd clouds, cool breeze from west.
Vulture - Sparrow Hawk - Lewis Woodpecker
Long-tailed Chat - distinctly heard in the scotch broom on the hill for certain.
Dave and I thought we heard one at the 12-mile Swamp on May 6th, too.
Lazuli Bunting - Dave heard its song, and I located the bird on the east side of an
oak, and it gave its call at least once a minute while we were in the area.
Vesper Sparrows singing and flitting everywhere.
Chipping Sparrows - male carrying nesting material - grass.
On the east slope of South Cemetery Hill we checked a Bush Tit nest reported by Bob Storm.
The adults were in the area. The nest was at 6 1/2 feet in a very small oak, more or less
in the open. The entrance was on the north topside, and went in 1 3/4" before turning
downward. It was the smallest nest I have ever seen, not being over 7 1/2-8 inches long.
