Owls are probably the most fun of all birds to find in the wild. These were all shot during the day. I have yet to do any owl photography at night (I did go owling one night in the Berkeley Hills a many years ago but just heard a couple of owls with no sightings). 

Images here- Great Horned, Barred, Burrowing, Barn, Spotted, Northern Saw-whet, Short-eared, Long-eared (USA); Dusky Eagle-Owl, Spotted Owlet, Collared Scops-Owl, Short-eared, Brown Boobook (India); Verraux's Eagle-Owl (Kenya); Little Owl (Portugal); Hawaiian Short-eared Owl or Pueo (Hawaii); Spotted and Barred Jungle Owlet (Nepal); Spectacled, Mottled, Tropical Screech and Ferruginous Pygmy-Owl (Panama).

​Total species seen- 20 (including a sub-species, the Pueo).
