Individual towhees can have fairly large repertoires. The one reference I have is Kroodsma, D.E., 1971, Songs variations and sining behavior in the Rufous-sided Towhee Pipilo erythrophthalmus oreganus. Condor 73:303-308 which reports a repertoire size of 7. Plus, there's variation from individual to individual. Is it possible that it is hatch year bird that's just learning to sing? (I don't know if Towhees do that ad it seems too accomplished and consistent to be a beginner. Cheers! |
