The fruits, hips, on the wild roses that grow in Estonia are botanically aggregate fruits, or more specifically pome fruits. The picking of rose hips finished with the end of September, when the fruits became overripe and the first night frosts had pinched them, making the skin of the hips quite a bit softer.
Users at this second stage are the migrant and sedentary birds. Their beaks manage to crush the softened skins and get at the seeds of the rose hips. In nature almost nothing is left unused.
