Nelson's Sparrow
I believe this attractive sparrow was originally found here in late October. They are scarce secretive, shy winter visitors to salt marshes along the California coast, primarily larger bays. Three widely separated subspecies are recognized with California records referable to nominate "A. n. nelsoni" characterized by bright orange underpart coloration as seen here and more contrasting streaking. This race breeds locally in the northern Great Plains and usually winters on the Atlantic coast west to Texas. The other two subspecies are much duller. They breed in Hudson Bay and the New England coast. This species was formerly known as "Nelson's Sharp-tailed Sparrow." It was originally lumped with the Saltmarsh Sparrow under the name "Sharp-tailed Sparrow. The two were split in 1995 and the English names shortened and simplified in 2009. However this split may have been premature and there is mounting evidence of a hybrid zone between the two. Formerly placed in the genus "Ammodramus."
