Blue!

 

Western Bluebird (Sialia mexicana)

photographed in the Bodega Dunes, 5 February 2013

Although I didn't get a picture of it, one of the fun things about seeing Western Bluebirds at this time of year is that they often occur in flocks with Yellow-rumped Warblers — just like Eastern Bluebirds (Sialia sialis) do on the East Coast!
