The database consist of 323 records of the recovered mili-radiotransmitters dispersed by Jays in acorns from 9 feeding trays representing 6 landscape units. While ca. 80% of the transmitters have been cached inside the stuffed acorns, remaining 20% of transmitters were extracted by birds (or rodents) and dropped or left on trees. Besides the points precise (GNSS) georeferences, the tables contain a number of descriptive attributes of the recovered caches/ miliradiotransmitters, such as the way of an acorn cover, surrounding vegeation, etc.

Nine feeding plates have been installed in six units of post-farming landscapes: in subcarpathian foothills, in Sandomierska Basin, and in Silesian Uppland. Acorns stuffed with mili-radiotransmitters were placed on the feeders and acorns collected and cached by Jays were tracked with radio-scanners and antennas. During one and half months (from late September into mid November 2023) 280 acorn caches or sole transmitters (removed by animals from acorns) were recovered.
