There are four levels of difficulity. Level 1 covers the most common birds, level 2 includes more species, level 3 quizzes are equivalent to the exam for each country and for Western Palearctic. Level 4 quizzes contain all the species registered in your chosen country and the Western Palearctic.

Which species are featured in each of the different levels is decided by which country you have chosen. Full species lists for level 3 (exam) for the different regions are found on the front page by clicking the map.

Use the cursor on the photographs to zoom into details on the pictures.

In the "Several singing birds" quiz there will often be additional species in the background. By looking at the field "Media id" you can see how many species you are expected to check in the list (always 2 or 3). Then answer the 2 or 3 loudest species.

The pictures are provided for this project by photographers from different countries. All rights are preserved by the photographers, except where otherwise noted. The pictures may be used in this project only. You can donate your own photos to the project if you like.
