April 4, 1947, 5 p.m. 5 miles south of Amity, Oregon Canada Geese, a flock of some 750-800 were seen in a grain field to the east of the hiway. April 4, 1947, 530 p.m. Newberg, Oregon. As we drove thru the main hiway street in the jeep, we saw a pair of English Sparrows busily mating in the very center of the street, in the downtown business district. (No discretion at all !) April 5, 1947, Leadbetter's Peninsula, near confluence of Willamette and Columbia Rivers, below Portland, Multnomah Co. 9-11 a.m. Dave Marshall and Fred G. Evenden, Jr. Blue Heron - I saw my first real heronry, and it was definitely worth the trip to see it, too ! There were 150-200 nests in Cottonwoods growing along the N side of a small slough. Although there were acres and acres of Cottonwoods in the area, all the trees containing nests seemed to be in an area of less than an acre. Nests were from 50 feet height on up, with some up around 100' I would guess. Nesting trees didn't seem to be more than 100 feet from the slough. Some birds were still building nests, and carrying on with courtship displays such as "cresting", and bowing, etc., from lofty perches. Other nests apparently are completed for there were a goodly number of birds on the nests, and probably incubating eggs at this time. Shot-like sounds produced by hitting a stick against a log resulted in the flushing of even those birds on the nests. Mallards - a few pair were seen in various ponds, etc. Baldpates - just 5 were seen - 3 were males. Wood Ducks - several pairs were flushed from the "inland" ponds and sloughs. Golden-Eagle, immature (could also possibly be an immature American Rough-leg Hawk). Dark brown with mottling below. Black tip to tail, whitish band inside it. Whitish underwings. Tail broad and fanned widely. Wings deep. Head appeared to be elongate and rather pointed. Little Brown Crane - we saw one in flight over the top of the cottonwoods. Almost the size of a blue heron, and elongate neck was well seen. Flickers - a few Harris Woodpecker - Flushed an adult (sex ??) from a newly constructed nest cavity in a barkless, 15' Cottonwood snag (about 20" in diameter). The nest hole was at 7 1/2 feet on the NNE side. 1 3/4" in diameter. The hole went in about 2" before dropping into the "gourd" part of the cavity. Depth horizontally from the entrance to the back of the cavity was about 7 1/4". The cavity was straight walled from there to the bottom. The adult flew to a cottonwood some 40 feet away, and when we retired to watch the nest, it did not fly directly back, but flew by the nest snag and over to another cottonwood some 100 feet away. Violet-green Swallows Tree Swallows Crow Slender-billed Nuthatch and Oregon Chickadees. Seattle Wren Winter Wren - Dave and I heard this one singing but did not think anything about it until I happened to notice where the song was coming from - 30 feet up in the upper limbs of a young cottonwood. This is the first time I have ever seen it singing from a perch over a very few feet above the ground. Nearby were shrubs of various species, as well as logs, which it usually would select for a singing perch. It sang for over a half hour, too. Robin Ruby-crowned Kinglets - singing its light, warbling notes. Golden-crowned Kinglets Purple Finch singing - Towhee - Junco - Song Sparrow. April 4/5 1947 , New ERA, Clackamas Co., 330 p.m. A pair of Ravens.
