About BirdTab
BirdTab is a browser extension that shows a different bird on every new tab, with its photo, call and a few facts, and a set of tools for birders on this site: checklists for 253 countries, the common birds of each place, a quiz, and a migration map.

Where the data comes from
- Bird lists, names and sightings: eBird, run by the Cornell Lab of Ornithology. Species names and field guide order follow the eBird/Clements taxonomy (11,167 species). Lists for each country, state and province, and the last 30 days of reports, come from the eBird API.
- Photos and recordings: BirdTab’s own collection of openly licensed media from Wikimedia Commons, iNaturalist, xeno-canto and free photo libraries, each credited with its licence, and more photos and calls from the Macaulay Library at the Cornell Lab, shown from Macaulay’s own servers with the photographer or recordist named.
- Species descriptions: eBird’s species accounts.
- Weather for the feeder scheduler: Open-Meteo. Maps: OpenStreetMap contributors.
- Advice and facts: feeder cleaning intervals follow the Cornell Lab, Birds Canada and Audubon; flyway timings and hotspots follow the flyway partnerships, BirdLife International and long-running migration counts. The 150 quiz questions and these timings were checked against those sources in October 2026.
How the lists are built
Checklists list every species eBird has recorded in a place, in field guide order. That includes rarities, vagrants and introduced birds, so each region page also separates the birds seen regularly.
“Most common birds” is BirdTab’s own ranking, since eBird’s API gives no frequencies. The main signal is how recently each bird was last reported in the place: common birds are reported within hours, scarce ones weeks apart. For a country it is averaged over its states or provinces where we have them. Whether a bird is one of the country’s regular birds, and whether it is regular in similar countries, settle the rest. The ranking follows the seasons, so migrants rise in spring and autumn.
Species pages combine the eBird taxonomy and description with photos and calls, and list the countries where the bird has been recorded. 500 pages are published so far, starting with the most common birds of the US, Canada, the UK, Australia and India.
The migration map plots eBird reports, week by week, for 34 migrant species. The flyway explorer is a guide to general seasonal patterns, not live data.
How often it’s updated
Recent sightings and the common-bird rankings are refreshed every week for the US, Canada, the UK, Australia and India and their states and provinces, and every month for other countries. The migration map gains a week of reports each week during spring and autumn migration. Every page with eBird data shows the date its data was fetched.
Data last updated: 2026-10-13.
