“But all is not chocolates and roses in the world of animal courtship.”

Looking for a unique Valentine's gift? Why not take some inspiration from the animal kingdom's weird and wonderful mating rituals.

"Gift-giving is not unique to humans. Many animals give what biologists refer to as 'nuptial gifts' to their prospective mates," Jonathan Balcombe, Ph.D., the director for animal sentience with the Humane Society Institute, told BuzzFeed over email.

Male great gray shrike birds will offer females prey impaled on sticks, according to a University of South Bohemia zoology study published in BioOne. Size matters. The bigger the prey, the more likely the females are to mate. These little guys are socially monogamous, so they're in it for the long run.

But the females were more likely to reject their suitors if the silk-wrapping was not visually appealing or if it was poorly constructed.
