Aims of colour-ringing

Colour-ringing, or generally speaking colour-marking, is a valuable research tool for a variety of bird studies.

Short term research, such as detailed behavioural investigations of activities and interactions of a particular set of birds in a restricted area, or long-term research on demography and population dynamics, movements between breeding and wintering areas, phenology and migration strategies may be greatly improved by colour-ringing.

The use of colour marks, which are visible and legible at distance, dispense with the need to recapture birds to read the ring inscription as is typical of conventional metal rings.

More details on colour-ringing

For an introduction on colour-ringing techniques and information on projects in Europe navigate the Dirk Raes colour-ring birding new site (old version is here).

For more information on what is scientific bird ringing, what are methods of bird ringing and what is the role of bird ringing for understanding bird biology and ecology, as well as recognizing and addressing population and habitat conservation issues see the EURING brochure on Bird Ringing in Science and Environmental Management.

Important Remark on Colour-ringing in Europe
ALL recoveries of metal ringed birds MUST be reported to the finder's national ringing centre or to the address on the ring (see European Ringing Schemes at the EURING website);
If not otherwise stated, ALL recoveries of birds wearing color-rings as well as ALL colour-ring readings must be reported to the finder's national ringing scheme.

- For birds recovered or seen in the following countries all data
MUST be reported to the national ringing centre, respectively at the Helgoland Ringing Office for Germany, Vogeltrekstation Arnhem for Netherlands, the National Ringing Scheme at the ISPRA (the former Istituto Nazionale Fauna Selvatica) for Italy. This is a legal requirement and condition of being issued with a license to colour-ring birds.

- In some countries data on colour-ringed birds should be instead reported to the national colour-ring coordinators: for Denmark Jacob Sterup / for France L. Marion / for Belgium Jérémy Simar jeremy.simar@spw.wallonie.be / for Finland the Ringing Centre / for United Kingdom see addresses under project list

In order to avoid overlapping of colour ringing project - well before starting a colour-ringing project - all ringers MUST contact their national ringing centre and the cormorant colour-ring coordinator/s

Coordinators for all European colour-ring projects are:
-
Stef van Rijn Institute for Inland Water Management and Wastewater Treatment (RIZA), P.O. box 17, NL-8200 AA Lelystad, THE NETHERLANDS;
-
Stefano Volponi Wetlands International Cormorant Research Group, ITALY
