Oost, west, thuis best:Op welk schaal benutten individuele Kanoeten het Nederlandse Waddengebied?
Many bird species are site-faithful, not only to breeding sites but also to the areas used during migration and wintering. For Red Knots we already knew that they use very large home-ranges in the Wadden Sea (800 km 2 , equivalent to half the Dutch part of this area), whereas they have very small ho...

Many bird species are site-faithful, not only to breeding sites but also to the areas used during migration and wintering.
