Please note: Because this deck reached the 250MB maximum here on AnkiWeb, no further extensions will be made to it here. The deck has been uploaded to AnkiHub (https://app.ankihub.net/decks/5bf6faa9-ae42-4885-98d5-c47ba23e58e7), where future changes may be made. I will try to update the deck here as well in case of any changes to existing notes, for those who do not have access to AnkiHub. However, any new notes, if they ever are added, will not be included here.
This deck contains most of the common birds encountered in the Netherlands. I may add some more birds later on if I find I've forgotten any that are important, but the bulk of it is done.
It is fit for international students (questions are in English). Sources are http://waarneming.nl and http://xeno-canto.nl—images and sounds included make use of the creative commons license and sources have been given for all of them.
Questions per bird: Image → Name (if relevant, one question for female and one for male birds) Sounds → Name (if relevant, distinction between call and song; I might add alarm and courting calls at some later date)
Enjoy, and feel free to give me any feedback, be it positive or negative.
