xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of birds, orthoptera, bats, frogs and land mammals. Since it began in 2005, it has collected over 1,000,000 sound recordings from more than 12,900 species worldwide, and has become one of the biggest open collections of wildlife sounds in the world. All the recordings are published under one of the Creative Commons licenses, including some with open licences. Each recording on the website is accompanied by a spectrogram and location data on a map displaying geographical variation.

BugGuide (or BugGuide.net) is a website and online community of naturalists, both amateur and professional, who share observations of arthropods such as insects, spiders, and other related creatures. The website consists of informational guide pages and many thousands of photographs of arthropods from the United States and Canada which are used for identification and research. The non-commercial site is hosted by the Iowa State University Department of Entomology. BugGuide was conceived by photographer Troy Bartlett in 2003 and since 2006 has been maintained by John VanDyk, an adjunct assistan

Avibase is an online taxonomic database that organizes bird taxonomic and distribution data globally. The database relies on the notion of taxonomic concepts rather than taxonomic names. Avibase incorporates and organizes taxonomic data from the main avian taxonomic publishers (The Clements Checklist of Birds of the World, Handbook of the Birds of the World, BirdLife International, IOC Checklist and the Howard and Moore Complete Checklist of the Birds of the World) and other regional sources (e.g. all editions of the American Ornithological Society Checklist of North American Birds since 1886)
