Resumen de Crossbills (Loxia curvirostra) feeding on cypress seeds

Antoni Borrás, A. Cabrera, J. Cabrera

• Common Crossbills Loxia curvirostra typically feed on conifer seeds, but there is no record of the species feeding on cypress Cupressus spp. Here we report two instances, one in autumn 1989, and the other in spring 1994. This is related to the crash, in these two years, in the production of Black Pine Pinus nigra seeds.
