This can be difficult to assess. For instance, snowy owls will stay in the same spot for hours, every now and again giving some sign of movement like a turn of its head. This is normal behaviour, and there’s no need to worry. Just enjoy its beauty, from a respectful distance of course!
However, an owl on the ground with no kill can be cause for concern, especially if you can see an obvious injury like a hanging wing. If this is the case, contact your local licensed wild bird rehabilitator to determine the best course of action.
If the owl is on the ground and is bright-eyed, alert and symmetrical on both sides, it may be best to leave the owl alone. You can always check back in a couple of hours to see if the owl is still there. If it is, it’s time to contact your bird rehabilitator. If you are unsure who your local bird rehabilitator is, your provincial wildlife department should have a listing.
Generally, if the owl is in a tree or perched on something, it best to leave the owl alone. This is typical behaviour for owls.
