Came across this one the other day. How would you like to wake up to this in the morning!? An owl had flown into this English homeowner’s window and left this excellent imprint of itself with it’s “powder down” .
According to the Wikipedia:
Powder down is a special type of down that occurs in a few groups of apparently unrelated birds. In some species, the tips of the barbules on powder down feathers disintegrate, forming fine particles of keratin, which appear as a powder, or “feather dust”, among the feathers. These feathers grow continuously and are not molted. In other species, powder grains come from cells that surround the barbules of growing feathers. These specialized feathers are typically scattered among ordinary down feathers, though in some species, they occur in clusters. All parrots have powder down, with some species (including theMealy Parrot) producing copious amounts. It is also found in tinamous and herons. The dust produced from powder down feathers is a known allergen in humans.
No mention of owls however these members of the strigiformes order are definitely “unrelated” to parrots!
This is possibly what this critter looks like in real life:
