In classic literature and art, besides the aid of Peitho, the Erotes (essentially cupids) and many other minor gods, several sacred birds are explicitly described as pulling Aphrodite's golden chariot or acting as her direct messengers, carrying the powers of love and desire far and wide: sparrows, doves, swans, swallows and wrynecks.

Aphrodite was a multi-faceted goddess, and the Greeks worshipped her under different titles to separate these concepts:

• Aphrodite Urania: The goddess of heavenly, spiritual, and noble love. Represented by the graceful swans and nurturing doves.

• Aphrodite Pandemos: The goddess of common, raw, physical lust and irresistible sexual compulsion. Represented by the restless swallows, frantic sparrows and famously, the singular Iynx (who was transformed into a wryneck after using her spells to seduce, who else, Zeus).

• Aphrodite Areia: The incarnation prominently worshipped in Sparta and Cythera, where war and love were considered intimately connected. Contrasts with later classical Greek ideas that separated the two. Linked to her pairing and close mythological ties with Ares.

Lesser known is the period in which several gryphons of Nemesis, the goddess of indignation and judgement, joined Aphrodite's retinue.

Though the stoic, cold, guarding nature of the gryphon in the eyes of the Greeks was at odds with any form of a deity of lovemaking, and as such an unlikely association, these ones were decidedly different.

Aeons of service to Nemesis had stirred things in them. The endless physical burden placed upon their strong bodies, turning the immense Wheel of Fate to balance mortal fortune and drawing their divine matriarch's inescapable chariot to deal out swift divine retribution across the world... legendary beasts or not, in the end, they were still beasts. And such extreme circumstances can change even mythological tempers that seem set in stone.

The mighty avians pushed, and they pulled, and they flew and fought. With far too little room for relaxation granted by their infamously dedicated mistress, their hormones steadily piled up, reaching unprecedented levels and in the end, a few reached a breaking point. Something inside snapped.
Almost overnight, calm, steadfast workers and protectors became unruly, hot-tempered predators with a libido so monstrous it simply wouldn't be contained. They... bothered some of her attendants. Not to mention the other gryphons.

Having no use for them in this state and oblivious to the cause, Nemesis lend these fallen ones to Aphrodite, hoping that a few short centuries of doing what her entourage does best would pacify them.

They fit in perfectly and became loyal, highly effective agents of Pandemos, descending upon the mortal realm to represent and invoke maddening infatuation and the base instinct for reproduction.
The simple incorporeal proximity of one could make people experience a sudden, urgent need to procreate with the one their heart desired most, or in absence, really just about anyone. Something that would simmer for days. And should a pair of them decide to help each other douse a bit of their own aching need, this would cause mass orgies to break out within miles.

They were highly motivated to be their new mistress' champions of fertility, sometimes to a fault. And between this competitiveness and the constant burning of their own loins, that's where they tended to make their presence known to mortal females (sometimes one, often several) and take matters into their own paws...
