A powerful ornithology database that brings together scholarly content written by ornithologists from all over the world for over 10,000 avian species. Species descriptions provide: identification, distribution, habitat, migration, diet/foraging, sounds/vocal behavior, behavior, breeding, demography, conservation, IUCN conservation status, and systematics. Also includes maps, images, media, and sounds/vocalizations.

Search for plants by either their common or scientific names to learn about preferred growing conditions and maintenance tips, along with extensive information on the various benefits that plant offers. This resource also features plant lists; for example, bee-friendly plants or plants for drought, as well as lists of recommended native plants for nearly every US state and Canadian province.

Presents information about the ~4,650 vascular plants of Oregon. Interactive mapping of plant occurrences, a photo gallery, and a checklist of plants and their nomenclature provide curated biodiversity information for plant scientists, restorationists, land managers, natural resource policy makers, and native plant gardeners.

Biodiversity Heritage Library (BHL) is offered by a consortium of 12 major US and UK botanical and natural history libraries with a collection of 46,000-plus titles and 90,000-plus volumes. The biodiversity-related items range in date from 1450 to the present. The collection is patron driven; patrons may request items to be scanned into the digital library. This feature is particularly helpful for scholars who cannot physically travel to view rare documents. The scans are high quality, but some images are slightly crooked or off-center. However, this does not significantly affect the documents' readability. The download options are extremely helpful: individual pages, PDF, OCR, images, bibliographic information, or all options. Users may browse by Titles, Authors, Subjects, Map, and Year, and limit by language and contributing institution. Searching can be slightly puzzling to the untrained eye. A simple keyword search returns just a few of the possible results.
