Savannah Sparrow

Like the Least Sandpiper I wrote about in my last post, the abundant Savannah Sparrow has a wide range across North America. Also like the sandpiper, the sparrow usually returns to its nesting area. This behavior often results in reproductive isolation and genetic differentiation among breeding populations. Unlike the monotypic sandpiper, 17 subspecies of Savannah Sparrows have been described by ornithologists. To see some of this variation, look at my posts of birds from Minnesota and Florida. This sparrow was first named by Alexander Wilson, when he collected the first specimen near Savannah, Georgia (Wheelwright and Rising 2008).
