The House Sparrow "song" is a steady series of call-like notes (male, Mar, PA).
The variety of the notes is quite amazing. The following sonagrams of the first 8 seconds of the song show that almost every note is different. Perhaps the House Sparrow derserves more respect as a songster.
This repeated chlip chlip appeared to be a song by a male (April, PA).
