This is a LOL video. It is cute too. The impression I get is that the bird (a crow by the look of him/her) prefers feeding the cat. Perhaps they are better friends. The lady who cares for them all, calls the dog back after he/she thought about departing. An obedient bunch of companion animals.
I have to presume that all three were raised together. The cat is not altogether pleased by the attentions of the crow and saunters off.
