LEADBETTER PROPERTY, Bordered by Smith Lake and Willamette and Columbia Rivers, Multnomah Co., Oregon May 9, 1948 08:45 - 12:00 Weather - High clouds Observers - W.H. Telfer and D.B. Marshall California Heron - Spent some time looking at the rockery. From the sound, we would judge some young birds have hatched. Adults carrying nesting material to some extent. The rockery is as large or larger than our past estimate of 175 to 200 nests. It appears as though some additional nests have been made at the west end of the colony, but this is not certain. Mallard - A few scattered pairs. Wood Duck - Pairs here and there. Western Red-tail - One around the rockery. Herring Gull - One adult in beautiful plumage in a temporary lake above the club house. Harris Woodpecker Gairdner Woodpecker Wright or Hammond Flycatcher - There were a number of these birds in with western flycatchers next to the heron rockery. We were first attracted to them by their call notes which were so familiar to Bill from the upper Clackamas River and to me from Fremont Forest. They gave the call note similar to the western only ending in a slightly lower note in addition to the two slurred end notes. Observations on these birds showed little yellow on [illegible] the belly. A lighter colored wash extended down the belly in the form of a wide line. These birds were probably one of the two, hamondi or wrighti. It must be admitted that the difficilis also will give at times two slurred end notes. Western Flycatcher - see above. Tree Swallow - Throughout the area. One young showing the [illegible] washed brown underparts was observed perched on a limb be- side an adult tree swallow. The adult made several attempts at feeding the young one. This is rather early for young to be out, but on the otherhand I doubt very much that the above bird could have been a Bank swallow. Good observation was afforded. Western Crow - Along the Columbia Oregon Chicksdee - Found one nest in a cottonwood stub about 7' of the ground. It appeared empty so far as eggs as young, but we could see that it contained some nesting material and the adults were going in and out. Seattle Wren - Young appeared from the hole about 10 feet up in the dead top of a willow while an adult bird was feeding. Robin Western Bluebird - By the club house Sitka Kinglet - One individual chasing another. Cassin's Vireo - Heard only one. Western Warbling Vireo - Heard singing near the rockery. Bill also saw one. Lutescent Warbler - Only one Yellow Warbler - Singing everywhere Myrtle Warbler - One of several. A male showed his white throat very well. Black-throated Gray Warbler - Observed a quiet one near the rockery Yellow-throat - Only one - near the rockery Over
