Scientific bird ringing is a research method based on the individual marking of birds. Any record of a ringed bird, either through recapture and subsequent release, or on the occasion of its final recovery as a dead bird, will tell us something about its life. In addition, a series of measurements can be gained from the bird in the hand (morphometry, fat, muscle and moult scores etc.). Bird trapping and marking is one of the basic methods to study the biology, ecology, behaviour, movement, breeding productivity and population demography of birds. In this 4-day course you will learn the legal background as well as the basic principles on handling living wild songbirds, perform standard measurements, determination of species, age and sex, and of course how to attach a ring. The course will be held at the institute’s field station on Mettnau peninsula near Radolfzell. We will set up a series of 20-30 mistnets and do bird trapping all day round whenever weather allows. In between there is time for explanations, discussions and of course individual training of taking birds out of mistnets and of handling and measuring them. The field station offers very simple accommodation (6 beds in two rooms) and a very simple kitchen. Toilet facilities can be used in a house nearby. Self-catering has to be arranged.
