The main sense in Continental French, 'Chasse dans laquelle on attire les oiseaux vers des branches enduites de glu, par l'imitation de leur cri ou celui de la chouette, prise d'oiseaux aux pipeaux', does not seem to be relevant here. However, etymologically the word is the same, in this case referring to the chirping sound of a flock of birds (cf. piper²).
