The following lists include all frequencies of conventional transmitters (not satellite) that may be still beeping, according to the year of manufacture and to the information available on the bird in the General Database. Transmitters not working any more (recovered transmitters, exhausted batteries, dead birds) are deleted from the lists as soon as the related information is available.

You can also get (and print) an ordered "Field list" of all crane radio frequencies, with some useful comments on them (familiar relations, year/country of marking, etc.).

IMPORTANT NOTE:  If you are planning a radiotracking study with any other Western European species in the same frequency band (148.000 - 149.999 MHz), remember that the same band is also being used to study Great Bustards (Otis tarda) in Spain. Therefore, we kindly ask you to contact us to check the "empty" frequencies according to the geographical range of your study.

The following lists show nominal frequencies, according to the manufacturers, used in each country, but as receivers can slightly vary with time or with different receivers, we reccomend to look for the "Field list". It includes the frequency checked in the field by any of us last time we contacted the individual.
