eBird
eBird is a birding website and citizen-science platform from the Cornell Lab of Ornithology. Birders submit checklists of birds they see or hear, and those observations help build global maps, personal lists, scientific datasets, and conservation tools.
What eBird is
eBird is a website and web app at ebird.org for recording bird sightings, keeping birding lists, exploring maps, and contributing observations to science. Its official eBird Mobile app is available on the App Store and Google Play, so birders can enter checklists in the field and sync them to their eBird account.

From checklists to records
The core eBird entry is a checklist: where someone birded, when they birded, how long they spent, how far they traveled, and which birds they saw or heard. That structure matters because a list with time, place, effort, and missing species is more useful than a loose sighting note. It lets researchers compare observations across places, seasons, habitats, and years.
Tools for birders
For everyday users, eBird works as a personal logbook and trip-planning tool. Birders can track life lists, year lists, month lists, regional lists, photos, sounds, hotspots, recent sightings, alerts, and species maps. The mobile app supports offline use, which is important when birding in parks, wetlands, forests, and remote places with weak service.
Data quality
eBird does not treat every unusual record as equally certain. Its filters suggest likely birds for a date and region, and unusual species or unusually high counts may be reviewed by regional experts. Review can ask for notes, photos, audio, or correction. The goal is not to make the system perfect, but to make a large public dataset more consistent and useful.
Science and conservation
The Cornell Lab uses eBird data in maps, models, and research products such as eBird Status and Trends. These tools help show where species occur, how abundance changes through the year, and where some populations may be increasing or declining. Because the data come from many observers, the scientific value depends on careful modeling, clear protocols, and awareness of where people do and do not bird.
Strengths and limits
eBird's strength is scale: many people can document birds across many places and seasons. Its limits come from the same source. Observers vary in skill, effort, equipment, and access to places. Popular birding spots can be heavily sampled while private land, dangerous areas, or less visited regions may be underrepresented. Good use of eBird data means reading it as community science, not as a complete census of every bird.
Why it matters
eBird matters because it connects a hobby with public knowledge. A checklist made during a morning walk can help a birder remember a trip, help another person find birds nearby, and help researchers study migration, abundance, habitat use, and conservation change. It is one of the clearest examples of a website turning repeated local observations into a global scientific resource.
