Breeding Report 

In June 2013 the IUCN-Wetlands International Cormorant Research Group published the first technical report with national chapters from 23 of the countries that participated in the breeding count of Great Cormorants in 2012. A summary of the findings are contained on the results page and the full report is available here.

In November (or before) a final scientific report from the 2012-13 count of breeding colonies in the Western Palearctic will be published by the Cormorant Research Group. This report will contain national chapters from all the countries that decided to use this opportunity to publish their results in English. So for some countries the same chapter will be published in the technical report as well as in the scientific report. This final report will also include a chapter in which the overall results will be described and compared with the count in 2006.

Information on the EU Cormorant Platform

A table will be published on the EU Cormorant Platform in July. This table will give the number of nests for each of the countries that have a chapter in the first IUCN-WI CRG report. The table will include a reference for each country to the author(s) and a link to the pdf of the relevant national chapter given in the report.

The July update of the EU Cormorant Platform will also include information about the overall coverage reached during the breeding count in 2012-13 and during the winter roost count in January 2013.

Winter Roost Count - January 2013

Over the weekend of the 12th and 13th of January 2013 a large number of people across Europe took part in winter roost counts of cormorants. At the end of the day during the non-breeding season and especially during the winter migration period all cormorants from a given area aggregate at a communal night roost - a traditional site used night after night and year after year. This communal roosting allows observers to count the cormorants, and assists in population estimates. Following unusually mild temperature across Europe at the end of December, temperatures dropped and ice began to form in northern areas in January before the counts took place. 


National Report Published in Switzerland

The Swiss Ornithological Institute has published a detailed report on the breeding population of cormorants. Cormorant numbers showed a marked increase in 2012 with a total of 1,037 nests in 13 colonies. Read more here


Coverage of Europe during the 2012 count of colonies

The coverage has been very good, despite some difficulties with funding, man power and logistics. So far, 32 countries have participated and we wish to thank everybody who made the counts a success already. The countries for which we still have no or limited information about breeding numbers in 2012 are: Ireland, costal UK, Kainingrad, Bosnia-Herzegovina, Moldova, Romania, Turkey and Georgia. The Counts Project will give it high priority to find ways of organising counts of colonies in most of these "missing" countries in 2013. Some countries have provided us with the information from their counts and some countries have already published their results. Other countries are still working on getting the last bits of information.  


Finland 2012 Breeding Count Published

Finland has published breeding numbers from the 2012 national count. The Finnsh cormorant breeding population decreased compared to last year (from 17,712 pairs in 2011 to 17,108 in 2012), suggesting that the population increase has come to a hault.

Danish Cormorant Numbers Increased in 2012

A report published towards the end of 2012 showed that the Danish cormorant population has increased for the first time in years. The breeding population has been decreasing since the mid 2000s, but in 2012 numbers showed an increase (from 25,542 pairs in 2011 to 27,109 pairs in 2012). Read more in Danish  here
