Many cranberry growers on the Oregon coast are well aware that good pollination is necessary for quality fruit set. Multiple
visits to the flower deliver more pollen, which can increase the percentage fruit set, number of seeds per berry, and mature
berry weight. The better a bee is at delivering...
The impetus for this Project began in 1968-1973 with birders at the Marine Science Center (MSC). But in the past 10 or so years the focus has shifted to a county group, Yaquina Birders & Naturalists. 120 individuals or couples have each contributed 100 or more records with 51% of...
For more than a decade, scientists have argued about the warmth of the current interglaciation. Was the warmth of the preindustrial late Holocene natural in origin, the result of orbital changes that had not yet driven the system into a new glacial state? Or was it in considerable degree the...
From 25 April through 30 October 1992, I conducted 14 waterbird and raptor censuses at Cabell Marsh. I observed 33 waterbird taxa and seven raptor species, including hatch-year individuals of five waterbird species. The records for each census are given.
612 Harlequin Duck records are given for Lincoln County, and another 74 records are listed for other coastal counties. In Lincoln County, Harlequins are found mostly in winter, there were often more males than females, the most ever counted was 14, and there is no indication that they nested.

In 1984-1986, Bayer made 171 and 67 waterbird censuses at West Pond and East Pond, respectively. From 1974 through June 1992, Bayer and others also made an additional 138 and 110 observations at West Pond and East Pond, respectively. A total of 48 waterbird taxa were reported at West Pond,...
The purpose of this paper is to provide my results about the nesting of Double-crested Cormorants (Phalacrocorax auritus) and Brandt's Cormorant (P. penicillatus) in Tillamook and Lane Counties.
This paper supersedes and significantly revises my compilation of 1992. The focus remains on live birds seen on or from land, but special codes are now given for records of species only reported beached or at sea.
Additionally, confirmation codes are now listed for records of some rare species and...
