Voice - This sparrow can be heard day or night, in any season. Its highly variable song usually begins with a few clear notes, sweet, sweet, sweet, followed by short notes and trills which drop in pitch. In words some have described the full song as "Maids! Maids! Maids! hang up your teakettle-ettle-ettle". At the height of the breeding season the Song Sparrow may sing its song as many as 300 times an hour!
