Alpensegler: eine Paarung im Flug

AlpenseglerWährend einer Reise vom 1. bis zum 8. Juli nach Rumänien und Bulgarien konnte eine bemerkenswerte Beobachtung in den rumänischen Karpaten im Bild festgehalten werden. Ein Männchen und ein Weibchen des Alpenseglers (Apus melba) wurden gesehen, wie sie unter einem Felsvorsprung in einer Steilwand flogen und dabei über mehrere Sekunden die Begattung vollzogen. Dies konnte in einer wunderschönen Schlucht im Piatra Craiului Nationalpark nahe der Stadt Zărneşti (Zarnesti) mit der Kamera fotografiert werden. Zarnesti liegt südlich von Braşov (Kronstadt) und befindet sich ca. 180 km entfernt von Bukarest, der Hauptstadt von Rumänien.

In der westlichen Paläarktis leben Alpensegler vor allem in Südeuropa, hier insbesondere in Gebirgen. Wie Mauersegler (Apus apus) wandern sie über den Winter in das südliche Afrika. Wie in dieser Schlucht zu sehen, baut diese Seglerart ihr Nest in der Regel Continue reading Alpensegler: eine Paarung im Flug

Copula in flight of Alpine Swift in Romania´s Carpathians

Alpine Swift During a trip from July 1st till 8th 2013 to observe birds in Romania and Bulgaria a remarkable sighting could be noted. A couple of Alpine Swift (Apus melba) was seen flying below a crag in a steep rock and copulated for several seconds. This could be seen in a beautiful gorge near the town of Zărneşti (Zarnesti), in the Piatra Craiului Nationalpark. Zarnesti is located south of Brașov (Brasov) approx.. 180km away from the capital of Romania, Bucharest.

In the Western Palearctic Alpine Swifts breed in mountains mainly in southern Europe. Like Common Swifts, they are migratory, and winter in southern Africa. As happened in that gorge the species builds its nest on cliff faces typically. Alpine Swifts build their nests in colonies in a suitable cliff hole or cave. It is well known, that Alpine Swifts spend most of their lives in the air, living on the insects they catch but up to now, a copula in flight could not be photographed. At least Bird-lens could not find a photo on the web. Consequently Bird-lens is proud to show images of a flight copula of this remarkable species.

As is mentioned in the „Handbuch der Vögel Mitteleuropas“ (Handbook of the birds of Central Europe), Volume 9 “Columbiformes – Piciformes” by Urs N. Glutz von Blotzheim, the male Alpine Swift usually holds the female with the beak in the neck and with the feet in the back plumage of the quiet female partner in copulation. While the female raises its tail, the male winds down his abdomen. For the Common Swift (Apus apus), also a copula in flight is described. Bird-lens is proud to show images of a flight copula of the much scarcer species Alpine Swift. A copula in flight resembles a courtship flight. During courtship Continue reading Copula in flight of Alpine Swift in Romania´s Carpathians
