Visual Resources for Ornithology (VIREO), the worldwide bird photograph collection of the Academy of Natural Sciences of Drexel University, is a taxonomically curated collection of over 200,000 remarkable, scientific and historical images.

More than 700 photographers have contributed to the VIREO project making their work available for educational, scientific and commercial use by license from VIREO. Photos from the collection can be found in field guides, birding apps, text books and nearly anywhere bird images can flock.

No personal information is required to search, browse and collect images and the associated scientific data in a “Lightbox” for personal reference or licensing requests.
