If you mean the one in my photo, she's an educational bird who was injured and not able to be re-released. She does a birds of prey show at our AZ Ren Faire.I don’t understand how owls are used for falconry, with them being nocturnal and all I‘d think it would seriously hurt their eyes….The daylight sun is hard on them.
Having said that, I see the GH in our area active all times of the day. Mostly at night, but not only at night. The ones who live in the garden center at Lowes are very active all day.
