The magpie is a bird that disperses large seeds such as acorns, nuts or almonds in agroecosystems. This process is key to regenerating forests and regulating the environment. Like other species of corvids, a magpie can disperse up to 1,500 acorns in a few weeks. This is demonstrated by a series of experiments framed in various research projects in which the University of Granada has participated.
The use of seeds marked with radio transmitters inside has allowed researchers to know the distance at which they disperse the seeds, where they hide them and what percentage of them they recover, since some are forgotten and never come back for them.
