Welcome to iCORA:
iCORA is an online database for recoveries of colour-ringed and radio tagged Eurasian Cranes (Grus grus) in Europe. The iCORA website offers the possibility to report observations of individually marked cranes or to report bearings of radio transmitters. After that, the life histories of the reported cranes can be obtained.
Current data base:
At the moment, ringing projects from seven European countries work with iCORA. The database currently contains data about more than 3000 cranes ringed in Europe and more than 85,000 recoveries of these birds. Reports from cranes, where projects not use iCORA so far, are regularly forwarded to the relevant project leaders and ringing centers. On a long-term perspective we are working to develop iCORA as the main platform for all crane ringing projects in Europe.
More information about ringed cranes:
You can find more detailed information about ringed cranes here. Results about crane migration can be found at http://www.kraniche.de/Biologie/Zug.shtml.

Support of iCORA:
The realization of iCORA was generously supported since 2008 for three times through grants given by the North German foundation for Environment and Development (NUE), using revenues from the Bingo lottery.
"My reports" now marked with different colors:
To better follow up the status of your observation reports, all your observations under “My reports” are now marked with different colors.
New observation reports will be in blue color in the beginning, until the project administrators look at these reports and change their status. If a report was validated as correct, the observation will be shown in green color. If there are some doubts about the observation (e.g. the bird wasn’t seen in the region before), the observation will be labeled with “under reservation” and is shown in orange color. With this procedure we make sure, that no observations went lost, if they later on occur to be correct. All observations, which cannot be assigned to a specific crane, are marked with red color. Only clear misreadings or wrong reports will be deleted from the database.
Observations of cranes, for which ringing data are absent in the iCORA database or if ringers/projects do not participate in the iCORA project, are assigned as external data and marked with purple color. These data will be directly forwarded by us to the relevant projects and ringing centres.
If you want to make remarks or annotations to one of your observations, you can do it by using the contact form. You have to open the full report by clicking on the arrow symbol. In the next step you click on the letter symbol next to the ID of the observation. This ID will be automatically added to the contact form, so that admins can easily go to the right observation. Finally one request from our side: please do not flood the project admins with many requests, as we expect more than 10,000 new reports during the year 2016.
All different ring colors at once:
Input of frequencies improved:
Now also OpenStreetMaps available:
OSM contain many more details than other maps, especially more local site names than google.
Now also for smartphones and tablets:
A new version of iCORA is online:
The new version for instance allows a more easy input of observation sites, exact input of co-observers, more detailed information on flocksize, more easy information about site and habitat use as well as allows data input of readings of alphanumeric colorings and also metal rings. Additionally, also the life history reports are much improved. The pdf-versions now show a map with all recovery sites, but also information about co-observers, flocksize and relationships between birds.
More details about all improvements can be found under FAQ.
The new update of iCORA was again kindly supported by a grant given by the North German foundation for Environment and Development (http://www.nue-stiftung.de/), using revenues from the Bingo lottery.
Brown as a new ring color:
Due to intensive ringing of Common Cranes with color combinations in Germany since the late 1980s, the number of available free combinations using a pool of six different colors is decreasing rapidly. We therefore decided to use “brown” a new seventh color and we used such rings test wise in our study area in Northern Pomerania/Germany in summer 2016. The brown ring will only occur on the left leg as part of the new German country code “blue-brown-blue”. The use of brown rings goes back to a positive decision during a conference of the European Crane Working Group in Stralsund in 2010, while we now use these rings for the first time in the wild. Therefore you have to expect seven different colors (white, yellow, red, blue, green, black, brown) in color combinations of juvenile Common Cranes since year 2016
