The two requested surveys were performed using high resolution image survey methods. The initial schedule was to conduct surveys in December 2011 and January 2012, but due to weather constraints the conduction of the December survey was delayed until January 2012. Thus, the two surveys were performed in January 2012, one on 13th January and the second on 28th January. The high resolution image surveys were carried out from a survey altitude of 475 m.

The camera delivered images with a ground resolution of 3 cm, corresponding to an image foot print of 520 by 360 meters. Both surveys were performed under good weather conditions, with low wind speeds and good visibility and the obtained image quality gave good possibility to identify birds in the images.
