The Bee-eater (Merops apiaster) nesting in mountain areas

摘要

[The European Bee-eater (Merops apiaster), usually breeding in lower, warm latitudes up to July isotherm of 21°C (Cramp, 1985), has recently begun his expansion in northern Italy. Gregarious throughout the year, the European Bee-eater is a summer visitor in Europe. In 2017 a new breeding colony of four-five breeding pairs, has been found out in mountain habitat facing the plain at 1,250 meters a.s.l. in Italian western Alps, showing his expansion not only in northern latitudes but even in altitudinal environment].
