Why Yes, I am the Center of the Universe: Yellow-billed Magpie on the Tuolumne River


Just a quick single picture tonight. This is a Yellow-billed Magpie (Pica nuttalli), one of California's
very few endemic bird species. Endemics are those species that are found in one place and nowhere else in the world, and this magpie fits the bill very nicely. It is common in California's Great Valley and the Coast Ranges, and is found nowhere else. We almost lost it a decade ago when the West Nile virus decimated the flocks. More than half the population was wiped out. Luckily a few seemed to have had some resistance to the virus and the populations have stabilized somewhat, although not yet to the number that existed prior to 2004 when the virus arrived.

I was thrilled to see a flock of more than a hundred of the Yellow-billed Magpies flying over the campus of CSU Stanislaus a few weeks ago. I've seen as many as two dozen or so at a time on the bluffs above the Tuolumne River in Waterford in recent weeks as well. There are also at least two dozen living on the west campus of Modesto Junior College.

This one that I saw today was obviously saying that it was the center of the Universe by making sure it was framed correctly by the barbed wire.
