Those dealing with waterfowl conservation often encounter gaps in knowledge of the flyways of the various populations. These gaps may be filled, at least in part, by analysing ringing recoveries of the populations in question. As such data are, however, not easily available, it seemed useful to publish waterfowl ringing results in such a way that quick comparisons could be made.
The present paper covers ducks and geese ringed in the Netherlands and teal Anas crecca ringed in various parts of Europe. It is hoped that other waterfowl populations can be included in further publication.
