I believe the barn owl gif is there to represent the mystical/occult associations with this bird and with their fantasy masks. I had forgotten how much I love this particular bird, and thanks to Denny for pulling this image and reminding me of it.
They’re at their very most northern range here, and rare enough to be considered threatened. I had an opportunity to view one very close up (like 2’) at a wildlife park near here where they doctor injured raptors. I was blown away by their incredible beauty, the little jewels in their feather markings, the fascinating ruff, etc. If I remember my Mabinogian correctly, the Welsh name for these birds is gwen hwyvar, which would later become the name Guinevere in British folklore. Altogether a remarkable creature.
