Monarch (Danaus plexippus), Point Reyes National Seashore, Marin County, California - 13 November 2011.
There are the same two adults that I photographed last year as well as a new baby in the nest. Last year they raised two chicks this year it appears to only be the one.
At Exit 131 of I70, E of Columbia from the Holiday Inn parking lot. I believe it's an adult male.
