A cardinal lands on a birdbath, next to the birdbath is a feeder, after a while of happily playing and eating a blue jay flys over and lands on the bird feeder, as they chirp back and forth the birds seem to reach a peaceful agreement. Finally settling down they both play and eat a distance away from each other.
Even if they are different species they can cohabitate when special needs are met!
I hope we as society may learn from nature...
