Phänologie und Truppgrößen Ziehender Kormorane (Phalacrocorax Carbo) auf dem Wegzug in Mittelwestfalen

Abstract

The recent increase in the breeding population and the phenology of roosting Great Cormorants (Phalacrocorax carbo) are well described, but little is known about their migration patterns away from coastal areas. The few published data are based on older investigations, when the Cormorant was a rare breeding bird in Europe and thus a very rare migratory bird in inland parts of Central Europe. As a result of daily migration counts carried out in central North Rhine-Westphalia from mid-August to mid-November during 2001 and 2003, I describe migration patterns both throughout the autumn and within a day. Additionally, flock sizes are shown. Inland Cormorants migrate later in the season, seem to migrate in bigger flocks, and do not... (More)

The recent increase in the breeding population and the phenology of roosting Great Cormorants (Phalacrocorax carbo) are well described, but little is known about their migration patterns away from coastal areas. The few published data are based on older investigations, when the Cormorant was a rare breeding bird in Europe and thus a very rare migratory bird in inland parts of Central Europe. As a result of daily migration counts carried out in central North Rhine-Westphalia from mid-August to mid-November during 2001 and 2003, I describe migration patterns both throughout the autumn and within a day. Additionally, flock sizes are shown. Inland Cormorants migrate later in the season, seem to migrate in bigger flocks, and do not concentrate their movements to a particular time of the day, compared to birds at the coast. The presented data provide a valuable insight into the migration of these birds within Central Europe.
