Burrowing Owl (Athene cunicularia) photos by Larry Jordan

Last month I took a trip down to Wildhorse Golf Club in Davis, California, to see how this year’s crop of Burrowing Owls (Athene cunicularia) were doing.  I didn’t have nearly enough time to do a proper survey of the golf course to see how many owls were there but last fall I counted over twenty at this artificial/natural cavity breeding site.  This is a couple of owls at one of the many natural cavities in and around this golf course.

In California, most of these natural burrows taken over by Burrowing Owls are excavated by the California Ground Squirrel.

The Burrowing Owl needs fossorial (digging or burrowing) mammals to excavate its burrows in most parts of the country and the continued extermination of the California Ground Squirrel in this state is one of the reasons for the decline in Burrowing Owl populations.

In other parts of the country, the burrows are dug by badgers, foxes and prairie dogs and the owls are thought to dig their own burrows in Florida.

Two other major reasons for this owl’s decline are intensive agricultural practices and urban sprawl.

Fortunately, we had a successful breeding pair produce eight young this season near Chico in Butte County (click on photos for full sized images).

It was fun watching these youngsters flying from one perch to another, usually a rock or ledge, as they practiced their aerial maneuvers with their siblings.

This family is probably ready to leave for their wintering grounds soon. They have been coming to this location for several years for breeding season but we have no idea where they go during the winter months.

These were the best photographs I could get of this Burrowing Owl family with the digiscope from the road.  They nest on private property, like most breeding pairs, and we have not yet gotten permission to do closer study of this group.

Unfortunately, the owls seen on the artificial site in Chico earlier in the year have not been seen since May. I was really hoping that we had a breeding pair using that site but I don’t know what happened to them. We had seen three owls there at one point in the spring, then nothing.  I’m keeping my fingers crossed for next season.

The owls in Davis on the other hand, are permanent residents and can be seen at Wildhorse Golf Club any time of the year.  If you are travelling near Sacramento, California, I urge you to stop in Davis and give them a look.  You won’t be disappointed.  They are very approachable.

For those of you that didn’t know, I am the Burrowing Owl Habitat Manager for the Burrowing Owl Conservation Network, a project of Earth Island Institute.  “The Burrowing Owl Conservation Network advocates for the protection and restoration of the Western Burrowing Owl and promotes the preservation and careful management of habitat to prevent loss, foster healthy populations, and maintain intact natural communities for an ecologically sound future.”

Lesser Goldfinch (Spinus psaltria) Female photos by Larry Jordan

I have two 36 inch Nyjer seed tube feeders made by Droll Yankees that attract goldfinches and Pine Siskins like crazy.  Little did I know that Lesser Goldfinches (Spinus psaltria) like a bit of salad with their seeds.  Click on photos for full sized images.

According to one source I read, Lesser Goldfinches like the male pictured above, “nibble at leaf margins and eat small new leaves.”  Apparently, they not only like Nyjer and sunflower seed, they love the sunflower plant’s leaves as well.

Here you can see a few Lesser Goldfinches chowing down on a sunflower that’s growing next to a young Corkscrew Willow in our garden.

We actually planted the sunflowers mostly for the birds but they don’t produce many seeds when their leaves are all gone.

Well at least this activity must be keeping my Nyjer seed bill down a little bit 😉

Female Bufflehead at Nest Cavity photo by Larry Jordan

Make sure you stop by 10000 Birds to read my latest West Coast Beat Writer post on the Bufflehead (Bucephala albeola) as the female searches for nest cavities.  The post includes a great video showing hatchling Buffleheads leaping from a nest box!  Here is my video of the Bufflehead at Lassen Volcanic National Park.
