    List of tagged birds

    Moving the cursor to a point on the map, you can see a list of species of birds caught on the observed area.

    Look at the data in all these points, and name five bird species occurring more often. Tell me, what kind of birds are found mostly on the territory covered by the card.

    Find the five species of birds encountered less often. Reading profiles of this and other studies of the December freeze frame, determine whether there is something in common in localities where these birds were met.

    Write about their findings in the comments to this article.
