So, my neighbours have this bird cage in the back yard. It's really odd in a way, as the birds aren't really pets and I have never actually seen them patting them or anything.
But what I have noticed is, that the wild birds always come to tease the caged up ones. It's kinda interesting to see, because obviously the free birds want the cage birds' delicious food and maybe even their awesome hideout, whereas the cage birds want the free birds'....well....freedom.
Maybe staring at completely unrelated National Geographic underwater (and by underwater I mean SHARKS!) photographs will help you answer that question?
