365 Birding Challenge 2026 - SUDAMÉRICA



6th Edition of the 365 Birding Challenge

Sixth edition of the 365 Birding Challenge, which consists of birdwatching and bird photography competitions across South America throughout 2026.

The participation regions are: South America (total region), country regions (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, French Guiana, Paraguay, Peru, Suriname, Uruguay, and Venezuela), and subregions for the Southern Cone:

  • Patagonia (in Chile: Los Lagos, Aysén, and Magallanes regions; in Argentina: Neuquén, Río Negro, Chubut, Santa Cruz, Tierra del Fuego, and South Atlantic Islands provinces)
  • Argentine Littoral (Formosa, Chaco, Santa Fe, Misiones, Corrientes, and Entre Ríos)
  • Argentine Northwest (Jujuy, Salta, Tucumán, Catamarca, and Santiago del Estero)
  • Cuyo (La Rioja, San Juan, Mendoza, and San Luis provinces)
  • Central region (Córdoba)
  • Pampas (Uruguay, and the provinces of La Pampa, Buenos Aires, and the Autonomous City of Buenos Aires)

The categories are three: most species observed, most species documented, and best records.

The “most species” categories can be followed daily through the site reports, while the results of the “best records” category will be published at the end of the year.

How does it work?
The hosting platform for the annual competition is EcoRegistros. Based on the records published by each participant, the system automatically organizes the contestant rankings for each region in the "Observed" and "Documented" categories. It also automatically generates the species lists recorded in 2026 by each participant in each region.

You only need to publish your bird observation records throughout the year.

The material may also be used in the Freebirds project to enrich the species guide.

There are no prerequisites, and the event is completely free and open to everyone.

Anyone can participate. It starts on the first day of 2026 and ends on the last.

Just enjoy birdwatching and publish your records!
