I would say its a coincidence . Many birds eat snakes ; a few weeks ago I was gardening and a kookaburra swooped by my head and landed at my feet - they never do that, I have even tried to tempt them with food , they usually just fly off if I get too close . Not this time, right at my feet and proceeded to attack a red bellied black snake that was approaching me.. It thrashed the snake and beat its head in and ..... down the hatch, head first , gulp by gulp and just sat there . After a bit, with effort from the extra load on board,, it flew up into a tree.
It was very tempting to see it as an omen, the bird 'saved me' from the snake . But really, the snake must have not known I was there, as that type is shy of humans and always retreats , unless cornered or trapped . The bird's excitement at the prospect of a meal lead it to overcome its caution at approaching me . Besides, it probably is used to seeing me around by now and doesnt see me as a threat, just not interested , usually.
But it is an unusual and notable experience, just like seeing a bird fly overhead carrying a writhing snake, or also, a fish (we have big river eagles here, sometimes they fly off holding a big fish underneath ) , so people attribute things to it .
Anyway , so as not to totally rain out your parade, I offer you this tidbit ;
"The
Pleiades also figures in the
Dreamings of several language groups. For example, in the central desert region, they are said to be seven sisters fleeing from the unwelcome attentions of a man represented by some of the stars in Orion. The close resemblance of this to
Greek mythology is believed to be coincidental — there is no evidence of any cultural connection.

However, stars were commonly used to measure time and the seasons and to regulate daily activities before written culture, and long after in some cultures. The myths of the Australian Aboriginal people are, as around the world, to do with moral lessons and various reminders such as when to eat certain types of food, which is itself a cultural connection in the general form of the stories. Therefore, the study of the stars is probably the oldest knowledge on earth, such that it remains an intriguing possibility that aboriginal star knowledge does contain some fragments of a much older original culture. Aboriginal people came to Australia from Asia 50,000 years ago (well before Greek culture formed 3,000–4,000 years ago), and presumably the Aboriginal people originally came from Africa. While there is no hard evidence of a cultural connection, the possibility should not be written off, and the door is open to research to construct models of older human cultures, through the tracing of these narratives and other means such as linguistics."
