Savannah Sparrow (Passerculus sandwichensis) Science Article 4
In attempting to identify Ohio specimens of the Savannah sparrow, the writer was confronted with the usual difficult problem familiar to investigators in this confusing group of birds. He was not long in discovering what had already been suspected, that more than one geographic race is represented rather regularly among Ohio migrants, and furthermore, thatnot only are there numerous examples among the transients difficult of analysis, but that the breeding stock of the state was of doubtful racial affiliation as well.
