4 - The nuthatch, Nucifraga caryocatactes, collects the nuts of Pinus cembra in autumn, and scatters 6000 hoard stores with a deposit of 5 seeds each at 2-5 cm under ground. The bird finds more than 80% of the hoard stores. The left over seeds may germinate, typically forming small groups of even-aged pines. Photo: C. Burga
