Be more animal like

This has been on my mind lately.I watch the birds at the bird feeder and lessons could be learned from them.A male bird was taking care of his mate by bringing her seeds from the feeder.She was sitting on top of the post just a chattering as her mate worked gathering seeds.I have read that some birds have only one mate throughout life.They even mourn when the other passes away.Elephants do the same I think.I know certain breeds of ducks do this and maybe other animals do also.If only us humans would be more animal like in this respect.
