Yaquina Studies in Natural History (formerly Studies in Oregon Ornithology) publishes monographs about natural history in Oregon. The focus is on the abundance or occurrence of animals and plants at individual sites. Monographs are about 50 pages or longer and are based on systematic, repeated observations. Such site-specific information is needed for resource or species management, research, education, land-use decisions, or recreational wildlife viewing. These records are also essential to determine changes in animal and plant communities over time. However, such records are lacking for many sites in Oregon.

Shorter articles documenting bird distribution in Oregon are published in Journal of Oregon Ornithology.

Ten issues were published irregularly during 1986-2003. Hopefully, more will be published as time permits.
