Owl takes rare daytime flight over Arboretum

I've never seen the shape of a bird like that from underneath the chin, as it were - many pictures make it seem like owls have flat faces, but perhaps the feathers angle backward more when in flight?

Knock knock.
Who's there?
Magoo who.
Magoo who who
Oh Magoo’s goodness! Magoo has transmogrified into an owl! Magoo.
