Our pair of crimson rosellas are enjoying the bird seeds we have in the garden. Only one bird can eat at the one time, and the larger bird (assuming he's the boy bird) usually waits for the smaller one (the missus) to eat first - rightly so I say! His patience ran out the other day because after waiting for his turn for quite a while, he pecked the missus and she flew away! How ungentlemanly!
There was only one bird who came on Sunday so I'm not sure who was giving the other the silent treatment.
