Hello all,

Here's a blog post I put together. I'm interested in any thoughts or
feedback.

I use Christmas Bird Count data to illustrate that some of California's
most common resident birds (historically) have expanded their ranges
hundreds of miles north into Oregon, Washington, and British Columbia in
recent years. The increases are dramatic, highly correlated with each other
across a wide range of species, and coincide with rapid climate change.
