Am 18.5.2013 konnte ich Feldhamster beim Paarungsspiel beobachten. Alle Bilder lassen sich durch anklicken vergrößern.
Diese drei Hamster kamen plötzlich um die Hausecke geschossen und rannten über die Wiese.
|Verfolgungsjagd / Chase|
|Hab Dich! / Got you!|
|Kämpfen und Kugeln / Fighting and rolling|
|Runter von mir! / Get off!|
|Nur weg! / Let's get out of here!|
|Hechtsprung / Jump|
UPDATE 27.5.2013: in "Der Feldhamster" von Weinhold und Kayser wird die obere Hörgrenze mit 14kHz zitiert (nach Wendt, 1989). Dh. Ultraschall fällt wohl aus.
EnglishThese pics (click to enlarge) are from 5/18/2013. I was able to watch the mating rituals of European hamsters.
These three hamsters suddenly appeared around the corner of the house and ran in my direction. One managed to escape but the other two started a fight. One of them caught the other up at the edge of the footpath and then a ball of fighting hamsters rolled onto the footpath about 3 meters (~10feet) in front of me. They bowled over several times until one managed to shake off the other. He ran off and jumped to the safety of the grass(*) on the other side of the footpath before the other one could get back on his feet.
Interestingly, they were quiet the whole fight - not a squeak. At least not in the hearing range of humans. I don't know if they might have squeaked in ultrasonic, though. It anybody knows, please leave a comment.
(*) I would not call it a lawn. They do mow it sometimes but it's not manicured or anything. It's grass, wild flowers, wild grains and weeds - a nice habitat but not a lawn.
UPDATE 5/27/2013: in "Der Feldhamster" Weinhold und Kayser cite the upper hearing limit of European hamsters as 14kHz (according to Wendt, 1989). So, no ultrasonic.
