And that's why birds do it, bees do it
Even educated fleas do it
Let's do it, let's fall in love!

Interspecies mating isn't common enough for Cole Porter to have included it in his song, but apparently it happens in captivity on rare occasions.
When animals are in close proximity, sometimes they have to find love in unexpected partners. If the animals share enough common DNA, it is possible for them to produce a viable embryo, as evidenced by the wholphin born to a grey female bottle nose dolphin and a false killer whale at the Sea Life Park in Oahu, Hawaii in 1985.

A zebra with a horse is a zorse, a camel and a llama make a cama, a lion and a tiger produce a liger. So does a yak and bull make a bak?
All we know is a bird and a dog definitely make a dird.
