Aage V. Jensen Nature Fund and the Department of Bioscience, Aarhus University has since 2007 had a cooperation agreement on the monitoring of selected breeding birds in Vejlerne, one of the most important breeding and staging areas for wetland birds in Denmark. In 2014, Avifauna Consult handled the monitoring tasks. This report presents the results of monitoring of breeding birds in the area in 2014.

The purpose of monitoring breeding birds in Vejlerne is to contribute to the Danish National Monitoring and Assessment Programme for the Aquatic and Terrestrial Environments (NOVANA). This monitoring aims primarily to meet Denmark's obligations under the Birds Directive. The methods used for monitoring follow protocols described in technical instructions under NOVANA.

The NOVANA monitoring of breeding birds in Vejlerne in 2014 was focused on, inter alia, Eurasian bittern, spotted crake and black tern.

A total of 99 booming bitterns was mapped in 2014, which is an increase compared to 2013.

Only four whistling spotted crake were registered, and this result represents a bad year for the species.

By contrast, black tern increased significantly compared to 2013 with a total of 34 breeding pairs, which successfully produced 19 fledglings.

The results of the monitoring of migratory birds in Vejlerne are not presented in this report, but data are stored in databases at the Department of Bioscience, and relevant data are included in the annual national NOVANA reports. For 2014 we refer to Holm et al. (2015).
