The purpose of this work is to make available reports and letters for
the Oregon Coast that were in the files of the Biological Survey and that
are now in the files of the Biological Survey's successor, the U.S. Fish and
Wildlife Service. I have changed outdated bird names to...
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.
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.
Birds perform valuable ecological functions and are useful environmental indicators. Avian distributions and diversity are predicted to change over the next 50 years. Little information exists on the role of local and regional conditions in fluctuations of avian communities over time. Historic datasets present a legacy of information that helps...
The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
