Im Sommer

Der Kampfläufer

Der Kampfläufer

Der Kampfläufer

Kampfläufer sind schon sehr komische Vögel. Die zu den Schnepfenvögeln zählenden Vögel zeichnen sich durch einen extremen Geschlechtsdimorphismus aus. Während die kleineren Weibchen unscheinbar grau-beige gefärbt sind, tragen die Männchen einen pompösen, harlekin-artigen Halskragen der von Schwarz, über Orange, über Braun bis hin zu Weiß variieren kann. Dabei sind alle erdenklichen Farbvariationen, mit Streifen und Mustern möglich, so dass jedes Männchen anders aussieht.

Auch ihre Überwinterungsquartiere im südlichen Afrika sind streng nach Geschlechtern getrennt. Gerade kehren sie in ihre Brutgebiete der nördlichen Tundra zurück, wo sie in feuchten Wiesen und Mooren brüten. Dort spielt sich dann wieder ihr außergewöhnliches Balzverhalten ab, dem sie auch ihren Namen verdanken: in etwa einem Quadratmeter großen, schlammigen Balzarenen kämpfen die stolzen Männchen um die Gunst der Weibchen.

Das größte Kuriosum diese Vogels, dürfte jedoch sein komplexes Paarungssystem sein, denn es gibt drei Arten von männlichen Paarungsstrategien. Die am häufigsten vorkommende Strategie ist die des „residenten Männchens“ (84 %). Sie haben im Brutkleid einen tief schwarzen oder kastanienbraunen bis orangeroten Kragen. Diese Männchen verteidigen ihre Balzarenen, wobei sie ein aggressives Verhalten vor allem gegenüber den Männchen zeigen die einen dunklen Kragen tragen. Hier balzen sie aktiv um Weibchen, die zur Paarungszeit zu diesen Arenen kommen, um Männchen auszuwählen.

„Satelliten-Männchen“ sind weniger häufig (16%). Sie sind marginal kleiner als residente Männchen und haben einen weißen oder zumindest sehr hellen Kragen. Sie verteidigen keine eigenen Arenen, stattdessen halten sie sich in der Nähe von residenten Männchen am Rande von deren Arenen auf. Auf diese Weise können sie ab und zu Paarungen ergattern. Die Satelliten werden von den Residenten geduldet, weil bei Anwesenheit eines Satelliten sich die Weibchen auch häufiger mit Residenten paaren. Beobachtet wurde sogar ein spezifisches Anwerbeverhalten der Männchen mit einem dunklen Kragen, bei dem sie hellkragige Männchen dazu auffordern sich ihrer Arena anzuschließen.

Eine dritte Strategie wurde von einem aufmerksamen friesischen Vogelberinger entdeckt: Ihm fiel auf, dass es zwischen den Flügellängen der größeren Männchen und der kleineren Weibchen noch eine mittlere Größengruppe gab. Die Vögel der mittleren Klasse, die sehr selten vorkamen (<1%), sahen aus wie Weibchen. Sowohl durch Sektion von toten Tieren als auch durch DNA-Tests wurde festgestellt, dass es sich bei diesen Vögeln ebenfalls um Männchen handelt. Diese Männchen, „Faeder“ genannt, mausern nicht ins Brutkleid, sondern behalten ihr schlichtes Federkleid auch zur Paarungszeit. Auf diese Weise erschleichen „Faeder“ sich Paarungen, indem sie vorgeben, weiblich zu sein, und so den Aggressionen der Residenten aus dem Weg gehen können.

Bei der Kinderaufzucht sind sich jedoch alle männlichen Kampfläufer einig, denn die bleibt denn Weibchen allein überlassen.
