Gary:
I was invited on a bird-banding for wood ducks and saw-whet owls earlier this year.  I got a kick out of the number of mice/rodents that were delivered to this owl’s nest.
John Ratcliffe, Brentwood, California

John:
It was nice of somebody to put up the wooden nest box this little owl is using. Saw-whets, barn owls and other owls like to use man-made nest boxes. It’s not always easy to find hollows or old woodpecker holes in trees.

Saw-whet owls may only be 8-inches tall, but they are one of the most aggressive little hunters in the bird world. From the way this owl (probably the female) is puffed up and her body is spread out, I suspect she’s keeping 4-6 babies warm under her feathers. All those fresh, dead mice lying around her were brought by her mate so she can feed her hungry chicks.

There used to be some saw-whet owl nests in the trees around San Pablo Reservoir near Orinda. Maybe there still are. /Gary

Great horned owl nest in tree, with chick and adult owl

I get a lot of requests from readers, asking what great horned owl nests look like. These photos by Dave Harper of Oakley, California, are a perfect example. It’s usually a large stick nest, high in a tree. Above you can see an approximately 3-month-old owl chick on the left sitting on the nest, staring at the camera. One of the adult great horned owls is perched on a branch on the right. Below is the same photo showing the owls and nest from a further distance away so you can get a better idea of how high up in the tree it is.

Hope this answers your questions. Thanks for the great photo, Dave! /Gary

Wild birds help us connect with nature

Native Bird Connections is a nonprofit organization that uses a collection of live, tame, nonreleasable eagles, hawks and owls to educate people of all ages about the wonders of nature. Last year they presented 584 programs that touched the lives of 17,792 people — including school children, scouts, senior living programs, after school enrichment programs, state and national park programs.

As Native Bird Connections supports our young people in their search for knowledge of the natural world around us, this organization also needs our financial support to help them survive these tough times.

Gary:
I feel so grateful for having a wonderful treat to marvel at each day:  A mama and papa screech owl have been living in my attic/house vent for over 8 years now.  Each spring they bring new baby “owlies” to my backyard.

The mama and papa are comfortable with my quiet presence. Their wings have brushed my shoulders on several occasions. The feeling is absolutely awesome.

Barn owls (not partridges) in a palm (not a pear) tree

Gary:
I thought you might like this photo for your wildlife shots.  I continue to take photos each day of the owls in our unsightly palm tree.  I love watching the owls take flight just as the sun goes down and the different sounds they make communicating.  It is so awesome.  And I cannot believe how many pellets they drop each day.  It is amazing to see the tiny bones and huge teeth in the pellets.
Linda Cruz, Clayton, California

Linda:
What beautiful barn owls!
Your “unsightly” palm trees are known by owls and other birds (squirrels and sometimes raccoons) as “Wildlife Condos” because of all the nooks and crannies that make excellent nesting spots. Show me a palm tree and I’ll show you a lot of happy, nesting wild birds!

The “pellets” you’re talking about are the undigested remains of fur and bone that the owls regurgitate after each rodent meal. Owls swallow rats, mice and gophers whole. What they can’t digest (bone, fur) gets coughed up later as a furry pellet that lands on the ground. Scientists often collect and dissect these pellets to expose rodent skeletons so they can study what the owls have been eating. Clever people, these scientists! By the way, the fact that these two owls are coughing up so many pellets every day indicates they may be feeding baby owls up there. /Gary

Screech owls are spunky, tough little guys. Isn’t this cute?

Gary:
During the 5 years I have had my owl boxes up, they have continuously been occupied by screech owls except for a 3 month span in one of the boxes when a tree squirrel took residence. The squirrel was eventually chased out by an owl.

These creatures are a constant source of delight and have helped to reduce my gopher population. Enjoy!
Craig Jensen, Walnut Creek, CA

Craig:
The 6-inch tall screech owls are one of my favorite birds of prey … tiny but very spunky! /Gary

Got owls? Photos & facts of our local owls to help you ID them

Barn Owl by Brian Murphy, Walnut Creek, Calif.
barnowl1

There are 8 species of local owls that you might encounter in your San Francisco Bay Area backyard. Four of these owl species are pictured here. There are links below for you to click on and take a look at the other four owl species on the Internet. Have fun! /Gary

Barn Owl: Probably our most common local owl in the S.F. Bay Area. These owls have white breasts and underwings and if you look up you may think you are looking at a white or snowy owl. Nope. Just a barn owl. Sometimes at night you will hear a loud hissing-screeching sound in the sky above you. Classic barn owl. They nest in old buildings, tree hollows and in human-made nest boxes. They eat LOTS of gophers, rats and mice. VERY beneficial — especially if they live in your backyard. More at http://en.wikipedia.org/wiki/Barn_Owl
