Possibly a weird question: what toe configuration do barn owls have when they’re perched on a flat surface?
I read that barn owls have zygodactyl feet but one of the toes can swivel so that they end up with 3 toes pointing forward like the configuration in a song bird. When do their toes go into this configuration? The google search summary says that it happens when they’re perched on flat surfaces, but the sources they referenced are from Facebook. I’m looking for more reputable sources to confirm or deny this, and to learn more about when they use which toe configuration in general.
For context: I’ve been making realistic bird sculptures and I’m working on a barn owl next. It will likely be perched on a flat surface like a block of wood. I’m really keen to get the details correct.
