Popis: | Mediterranean Crossbills are as much differentiated as L. scotica and L. pytyopsittacus. They are sedentary, linked to pine trees and have evolved a thicker bill to extract the seeds from Pine cones. Their decolorization could be due to dietary causes. The authors studied biometrics, breeding phenology, and primary food of Italian populations living in Calabria and Etna (Sicily) and compared them with the other Mediterranean populations. A coevolutive radiation between the different populations of Mediterranean Crossbills presently living in the three main peninsulas, adiacent islands and North Africa occurred separately and this may be demonstrated by their morphometrics, their sedentariness, as well as by songs and some genetic results recently published. They conclude that the same criteria followed to raise L. curvirostra scotica to the species rank as scotica occur also for the different Mediterranean populations. |
