Sparrow / Sperling

The house sparrow is a bird of the sparrow family Passeridae, found in most parts of the world. Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings.
Most house sparrow vocalisations are variations on its short and incessant chirping call. Transcribed as chirrup, tschilp, or philip, this note is made as a contact call by flocking or resting birds, or by males to proclaim nest ownership and invite pairing. In the breeding season, the male gives this call repetitively, with emphasis and speed, but not much rhythm, forming what is described either as a song or an "ecstatic call" similar to a song.
