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 compilation is meant only to be a guide because it is imperfect. I gathered these citations during a single search of the sources cited in section B; ideally, I would have gone through all those sources again to perhaps find records that I missed or to correct errors that...
I conducted 14-22 waterbird and raptor censuses each year from 1992-1995 during late April or early May through October. I observed 44 waterbird and 13 raptor species, including hatch year individuals of seven waterbird species. The records for each census are given.
John H. Wampole's list of the birds of the Coos Bay area from 1958-59 is one of few such compilations from that region, and the only reasonably accessible one from its era except for Giesler (1952), which covered only the Cape Arago region. Wampole's list has been circulating informally as...
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...
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...
The monthly occurrence of subspecies for 18 terrestrial species are given. The greatest differences in seasonal status appear to be among subspecies of the American Robin, Yellow-rumped Warbler, Savannah Sparrow, Song Sparrow, and Dark-eyed Junco.
There were 21 days with observations during 30 January-21 May 1974. Herons were already displaying on January 30, so nesting activity can occur much earlier than has been supposed. A yearling was often seen at the nests, but most nesting activity was by adults. Although eggs were laid in at...
The results of 703 observations are given; most of these were made in the 1930's by James Macnab, Jane Claire Dirks-Edmunds, Dorothy McKey-Fender, and others. These results are the most comprehensive throughout the year for any site above 1,000 ft in Lincoln County and hint that bird communities at sites...
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...
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.
These observations were sporadically made at my home in 1975-1977 and 1982. In spite of their casual nature, this article gives some information about the seasonal status of species at this site.
This is a continuation of Faxon and Bayer (1991), which summarized Faxon's 1973-1990 observations. In 1991, Faxon made observations during 168 days and recorded 111 species. Monthly frequencies of occurrence are given for each species.
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,...
There were 5,776 records during 1981-1986 observations, with 99% of these observations during Schrock's systematic 1982-1985 observations. He found 32 waterbird and 99 landbird species. 16% of the waterbird species were noted each year during 1982-1985, and 58% of the landbirds were recorded each year. Semimonthly summaries of the observations...
This article includes 609 observations, 531 of which were by Llewellyn. This article is an amalgamation of incidental records for various specific and general areas.
