We carry out breeding bird inventories according to the national breeding bird survey standards ('extensive territory mapping') and, if required, according to the guidelines of the Dutch Nature and Landscape Management Subsidy System (SNL). During surveys, we record all relevant observations in the field using a field computer. During each field visit data are synchronised live with our online database.
We also carrying out counts of colony-nesting birds with the help of our licensed UAV pilots and dedicated image analysis techniques.
