Versagensangst

Der tollkühne Mauersegler

Mit ihren durchdringenden „sriih-sriih“-Rufen verbreiten Mauersegler dieses herrliche Sommerfeeling in den Städten. Mit Spitzengeschwindigkeiten von bis zu über 200 km/h jagen die Trupps durch die Häuserschluchten. Der rasante Flieger hat sich in Städten und zunehmend auch Dörfern als ein echter Kulturfolger angesiedelt, wo er unter Dächern und in Gebäudenischen geeignete Wohnstuben findet.

Nur zur Brut begibt sich der Mauersegler auf festen Boden. Die übrige Zeit seines Lebens verbringt er komplett in der Luft. Er frisst in der Luft, trinkt in der Luft, schläft in der Luft, betreibt Körperpflege in der Luft und vermag sogar die Paarung im Flug zu erledigen. Dank seiner sehr langen, sichelförmigen Flügel, einem kurze Schwanz und eines abgeflachten Kopfes bringt er die perfekten aerodynamischen Vorraussetzungen für das Leben in der Luft mit. Auf Grund seiner Wendigkeit kann er Insekten und Spinnen spielend aus der Luft fischen. Über ruhigem Wasser trinkt er während des Fluges oder nimmt ein Duschbad, indem er mit Hilfe des Schnabels das Wasser aufspritzt. Zum Schlafen steigt er auf in warme Luftschichten bis zu 3600 Meter. Dort schläft er in einer Art Gleitflug.

Der Körper des Seglers ist derart an das Leben in der Luft angepasst, dass er nur noch verkümmerte Klammerfüße hat um sich an den Nestern unter Gebäuden, oder wie ursprünglich, in Felsen und Klippen festzuhalten. Landet ein Mauersegler doch einmal auf dem Boden, ist er nur noch ein hilfloser Krabbler, da er kaum noch Laufen kann und auch der Start nur mit Mühe gelingt.

Messungen von mit Sendern bestückten Tieren haben ergeben, dass der Mauersegler in seinem bis zu 20 jährigen Leben etwa 4 Millionen Kilometer zurück legen kann oder 97 mal die Erde umkreist, oder er damit 10 mal mit zum Mond gelangen könnte. Schon unmittelbar nach dem Flügge werden ziehen die Jungvögel non-stop bis in den Süden Afrikas.

Bei diesen unglaublichen Leistungen erreicht der Puls des Mauerseglers bei Geschwindigkeiten von  200 km/h etwa 700 Schläge. Sein Blut ist wie ein Superkraftstoff: in 100 ml Blut können etwa 300 mg Blutzucker nachgewiesen werden, der Normwert beim Menschen beträgt 70-100 mg. Auch die Körpertemperatur des Mauerseglers liegt bei für uns tödliche 44 °C.

Mit all diesen Superlativen gehört der tollkühne Mauersegler zu den faszinierendsten Vögeln unserer Breiten.
