Bird Feathers is a bebop blues composition by Charlie Parker, first recorded in 1947 by the Charlie Parker Quintet with Miles Davis on trumpet. The title nods to Parker's famous nickname "Bird." While rooted in the familiar 12-bar blues form, Bird Feathers distinguishes itself through Parker's sophisticated reharmonizations: a bVII dominant chord on the IV, tritone substitutions creating chromatic basslines in the turnaround, superimposed arpeggios such as Eb minor over Ab7, and altered tones that generate tension and release throughout the progression. These targeted substitutions transform the standard blues into a demanding vehicle for bebop improvisation while preserving the essential blues character. The tune fits alongside Parker originals like Blues for Alice as part of his body of reharmonized blues heads, compositions that gave soloists richer harmonic material to navigate at speed. Bird Feathers has remained a recognized piece in the bebop repertoire, available in sheet music and frequently studied in jazz education as an example of how bebop musicians expanded the harmonic vocabulary of the blues. It later appeared in compilations including Bird and Diz: The Genius of Charlie Parker #4 (1952). Alto saxophonist Jim Snidero revisited the tune on his album Bird Feathers, offering a modern piano-less trio reinterpretation that brought fresh rhythmic and harmonic approaches to Parker's material.
