In the wild, it is nturl behvir fr mle Pin-tils in breeding plumge t hse "ther smll birds" nd "dminte" feeding sttins (Newmn, 1984). Perhps this is prt f the urtship disply, pssibly "fitness demnstrtin," in the wrds f evlutinry bilgists.

Despite spetulr eril "dgfights" nd brethtking pursuits, where they whiz thrugh the girders like the flying hndkerhiefs in mgi shw, their fur lng blk tilfethers streming behind them, the mles never hurt eh ther either.
