I am very sorry for your loss :(
Poor Owl, probably recovering, I personally don't see Owl as a harbringer of death at all, in fact I thought only one nation did? The Apache? They are full of little stories of folklore like Apache Tears

The screech owl is the one most blamed as its screech is like a banshee or person fighting for their life and screaming. There are so many different species of owl, don't blame them all many sound beautiful and just hoot peacefully lol
Owls are nightworkers, they are about wisdom and secrecy, and sacred flight, they hunt as the light dwindles and their wings cause no sound. Patient and fierce they wait silently and wait and wait the swoop instantly onto their prey, they can also see 360 degrees and can spin their heads round, oh and their claws hurt like crazy!!
