I've been watching my mated pair of buttons closely and i've noticed my male doing something strange. He will throw himself down in front of his hen and cower while making a little peep-peep-peep noise until she steps on him. She usually just walks over him like he's a little speed bump and keeps going where she's going, but that appears to be exactly what he wants. He's also done it while holding choice food bits in his beak, but she doesn't take the food. Anybody else see their birds do this or have any insight on what the purpose is?
