The highest breeding density of the Eastern Imperial Eagle (Aquila heliaca) population in the Carpathian basin can be found on our chosen area in the Jászság region. This land was the main project area of the European Union Helicon Life+ program that ran between 2012–2015, during which we GPS marked nestlings in the nearby regions. The markings took place between 2011–2015. In 2011 one nestling, in 2012 five were marked with GPS-Argos (Microwave) transmitters. In 2013 four nestlings, in 2014 also four and in 2015 one nestling received a GPS-GSM (Ecotone) transmitter. We examined altogether 12961 occurrence points of 14 neighboring birds. From these data using the QGIS Spatial Point pattern analysis algorithm, we created the polygon of the territories
