I saw a bird today that I was unfamiliar with and was hoping the Dope could help me identify it. I’m not a birder, but I spend a lot of time outdoors. This bird was new for me.

I saw the bird in the hills surrounding the SF Bay Area.  
I saw the bird standing on the ground, not in flight.  
The bird was just a little bit smaller than a crow (or about the size of a small crow).  
The bird was solid black on top and solid white on the bottom.  
With its wings folded, there was an oval white stripe on its wing running (approximately) parallel to the ground.  
I saw 2 of these birds at once, and their markings didn’t seem to be very different from each other.  
I didn’t notice any other colors on the bird.  
I can’t really describe the bird’s beak, but I remember thinking “that’s not a raptor’s beak”. The beak also was not very long (like a hummingbird’s beak). It just looked “normal”.

What kind of bird do you think it was?

Thanks,  
J.

Sounds like a[Yellow-billed Magpie.](http://www.birdinginformation.com/wp-content/gallery/yellow-billed-magpie/yellow-billed-magpie-9a.jpg)

They are mostly in the Central Valley and south of San Francisco, which may be why you have not seen them previously.

If it had been in Europe I would not have hesitated to say “magpie”, but since I had to ask myself the question “Are there magpies in California?”, **Colibri** beat me to it.

In fact, a bird nearly identical to yours, perhaps even the same species, is common throughout western North America:

> The black-billed magpie (Pica hudsonia), also known as the American magpie, is a bird in the corvid family found in the western half of North America. It is black and white, with the wings and tail showing black areas and iridescent hints of blue and blue-green. It was once thought to be a subspecies of Pica pica, which was known as the black-billed magpie at the time, but was placed into its own species in 2000 based on genetic studies. Currently, Pica pica is the scientific name of the Eura...

The referenced yellow-billed magpie inhabits California, and looks identical to that one, except for having a yellow bill, and apparently, a yellow ring around the eye.

Yes, I believe the black-billed magpie is the one. Some of the pictures on Wikipedia didn’t look quite right, but looking in Google Images produced a couple of pictures that looked identical to what I saw.

As always, I knew I could rely on the Dope.

Thanks,

It’s very unlikely to be a Black-billed Magpie. That species is not normally found near San Francisco, but only on the eastern side of the Central Valley. The birds you saw were almost certainly Yellow-billed Magpies, a closely related species that only occurs in California. Yellow-bills are known to occur near San Francisco.
