EuroBirdPortal, the European citizen science portal on birds, publishes its interface in 38 different languages: from Catalan and Basque to Hebrew, Maltese and Ukrainian. It’s an unusual figure even among European Union funded projects.

The figure isn’t a stray marketing detail. It reflects the strategy of EuroBirdPortal: turning scattered observations from thousands of people into a single, near real-time map of bird migration across the continent.
TL;DR
- EuroBirdPortal centralizes citizen observer data from dozens of national portals to map bird distribution across Europe.
- Its interface is available in 38 languages, counted directly from the site’s selector: from Irish Gaelic to Ukrainian.
- The project operates under the European Union’s LIFE program, with an active phase identified as “LIFE EBP reinforcement.”
- The public species catalog visible on the site exceeds 75 entries before cutting off, from the common quail to the great crested grebe.
- Each species has “L” and “R” checkboxes next to its scientific name, without the site publicly documenting their exact meaning.
- EuroBirdPortal doesn’t publish a documented REST API on its main page, unlike aggregators like GBIF.
- EBP’s model anticipates a broader trend in open science: unifying heterogeneous sources under a single multilingual viewer.
What happened with EuroBirdPortal
The main menu of eurobirdportal.org now includes, alongside “Home,” “Help,” “About,” “Partners” and “Blog,” a direct link to “LIFE EBP reinforcement.” The name identifies the project’s reinforcement phase within the European Union’s LIFE program, the financial instrument the EU has used for environmental projects since 1992.
That navigation detail confirms something simple but relevant for anyone following publicly funded open data projects: EuroBirdPortal remains active in 2026 and continues receiving European budget to scale its infrastructure. It is not a project that was abandoned after its initial launch.
The menu also includes a section dedicated to “Partners,” confirming that the project functions as a consortium: it’s not a single institution processing data, but a network of national organizations contributing their own records to the central aggregator.
The site’s own species selector is another sign of the project’s scale. Counting directly the entries visible before the list cuts off, more than 75 distinct species appear, from the common quail (Coturnix coturnix) to the great crested grebe (Podiceps cristatus), including geese, ducks, swans and mountain grouse. Each row includes the common name, the scientific name and two checkboxes marked “L” and “R,” probably to toggle between map layers (local and regional), though the site itself doesn’t explain this in the publicly available HTML.
Context and history
Ornithological citizen science didn’t start with EuroBirdPortal. National portals like trektellen.nl in the Netherlands or the ornitho project’s networks have spent more than a decade collecting volunteer sightings across different European countries, each with its own data schema, its own interface language and its own server.
The problem EuroBirdPortal solves is one of integration, not capture: the data already existed, but it was scattered across national silos that didn’t communicate with each other. An observer in Portugal and another in Finland could log the same migrating species in the same week without any system cross-referencing both records on a shared map.
That same problem (national data silos that don’t interoperate) is what led to the creation of GBIF (Global Biodiversity Information Facility) in 2001 as a global biodiversity data aggregator, and what drove eBird, from the Cornell Lab of Ornithology, to become the world’s largest repository of bird sightings. EuroBirdPortal tackles the same problem, but at a European scale and with an exclusive focus on the temporal distribution of bird species.
The consortium behind EuroBirdPortal isn’t the only European attempt to coordinate bird data at a continental scale either. The European Bird Census Council has coordinated Europe’s breeding bird atlases for decades, with multi-year cycles per edition. EuroBirdPortal’s difference lies in its cadence: instead of an atlas updated every two decades, it aims for maps that change week by week during migration season.
Technical details and performance
In the biodiversity citizen science ecosystem, the de facto standard for unifying taxonomies, coordinates and observation dates is Darwin Core, the schema GBIF promotes so datasets from different sources can be combined without rewriting each integration by hand. The pattern EuroBirdPortal follows (taking records from N national portals and producing a weekly map per species) fits that same normalization logic.
📌 Note: This is a reasonable inference based on how comparable biodiversity projects work, not confirmation that EuroBirdPortal uses exactly Darwin Core under the hood: the site doesn’t document its technical pipeline on its public pages.
| Platform | Geographic scope | Data focus | Developer access |
|---|---|---|---|
| EuroBirdPortal | Europe (participating national portals) | Weekly bird distribution by species | No public API documented on its site |
| GBIF | Global | Occurrences of any taxon, not just birds | Public REST API, no token, at gbif.org |
| eBird | Global, with strong coverage in the Americas and Europe | Individual georeferenced sightings | API with free key requested from the Cornell Lab of Ornithology |

How to start testing it
EuroBirdPortal doesn’t expose a documented public API on the part of the site accessible without authentication, so to experiment today with the same type of data (georeferenced bird occurrences) the most direct entry point is GBIF’s REST API, free and requiring no token.
curl "https://api.gbif.org/v1/species/search?q=Anser%20anser&rank=SPECIES"
This returns a JSON with the taxonomic record for the greylag goose (Anser anser), one of the species also listed in EuroBirdPortal’s selector. The key field in the response is the identifier later used to request occurrences for that species.
import requests
# Use the "key" returned by the previous step (curl to /species/search)
especie_key = int(input("Species taxonKey: "))
params = {
"taxonKey": especie_key,
"country": "ES",
"hasCoordinate": "true",
"limit": 20,
}
resp = requests.get("https://api.gbif.org/v1/occurrence/search", params=params)
data = resp.json()
print(f"Records found: {data['count']}")
for registro in data["results"]:
print(registro["eventDate"], registro["decimalLatitude"], registro["decimalLongitude"])
The script requests occurrences of a species in Spain with valid coordinates and shows the date and position of each sighting. By changing country and taxonKey, you can reconstruct, with verifiable open data, the same type of map that EuroBirdPortal generates internally for its viewer.
💡 Tip: GBIF’s API doesn’t require a token for read queries, so you can paste the first curl‘s URL directly into your browser and see the JSON without installing anything.
To confirm the query worked, check that data['count'] is greater than zero and that each record has non-null decimalLatitude and decimalLongitude: if they come back empty, add the hasCoordinate=true parameter as in the example.
Impact and analysis
The real value of a project like EuroBirdPortal isn’t in the number of species it lists, but in how it turns the distributed effort of thousands of volunteer observers into a single temporal source of truth. Coordinating 38 interface translations and accepting data from portals with different schemas is, in essence, a continental-scale data integration problem, the same type faced by corporate data teams with much larger budgets.
The honest limitation is the one any citizen science aggregator faces: observation effort isn’t uniform. A country with more active observers and better coverage generates more records than one with fewer volunteers, and that can skew the aggregated map toward areas with more human activity, not necessarily toward areas with more birds. It’s a known bias in the citizen science literature, and not something EuroBirdPortal can solve just by adding more languages to the interface.
There’s also no API or raw data export on the site’s public pages: unlike GBIF, which exposes each individual occurrence, EuroBirdPortal seems to choose to publish only the aggregated map, not the atomic records that compose it. It’s a reasonable design decision to protect observer privacy and prevent misuse of exact coordinates for sensitive species, but it limits what an external developer can build on top of it.
What’s next
There are no official figures published on the exact scope of the “LIFE EBP reinforcement” phase: the site references it in its menu, but the public fragment doesn’t detail budget, new countries or added species. What’s verifiable today is that the project remains active in 2026 and still falls under European funding, which, for an open data project with no business model of its own, is already a relevant sign of continuity.
For anyone interested in biodiversity data, the pattern worth watching closely isn’t EuroBirdPortal itself, but the trend it represents: more and more open data projects are competing to be the normalization layer, not the original source, and they gain reach by publishing in as many languages as needed to add observers on the ground.
Try it yourself: paste the URL api.gbif.org/v1/species/search?q=Anser%20anser directly into your browser to see, in seconds, the same type of open data that feeds maps like EuroBirdPortal’s.

Frequently Asked Questions
What is EuroBirdPortal?
It’s a European citizen science portal that aggregates bird sightings from various national portals to generate distribution maps by species, updated as often as the data arrives.
Where does the data it shows come from?
From volunteer observers who log sightings on national citizen science portals, such as the ornitho project’s networks or trektellen.nl, among other consortium participants listed in its “Partners” section.
Do I need to sign up to see the maps?
The public site exposes the species selector and navigation menu without requiring a visible login in the accessible fragment; there’s no public evidence of a mandatory registration wall to view the map.
Why is it in 38 languages?
Because the project depends on volunteer observers spread across Europe, and lowering the language barrier is key for each country to contribute data to a shared map.
Does it have a public API like GBIF?
There’s no REST API documented on EuroBirdPortal’s main page. To work programmatically with the same type of data, the open alternative is the GBIF API.
Is the project still active in 2026?
Everything points to yes: the site references a reinforcement phase (“LIFE EBP reinforcement”) within the European Union’s LIFE program, suggesting continued funding.
