Afterthought on animal symbolism

[Carol]

It just occurred to me that the symbols of three of the four Houses at
Hogwarts (badger, snake, and eagle) are represented, as are two of the
three wand core animals (dragons and unicorns), as well as ravens
(which ought, IMO, to be Ravenclaw's symbol) and magpies (winks at
Magpie). The swan and hare )Cho's and Luna's respective Patronuses)
are also listed.
If you're curious as to how well the Celtic symbolism correlates with
the Houses and characters associated with those animals, the URL
(again) is

star, as regards his HP counterpart: "Dog days bright and clear;
Indicate a happy year."
