  - During complex vocal interactions, different features of acoustic stimuli are
    integrated to produce appropriate vocal responses,1 such as copying sounds during
    vocal matching behavior in some animals.2,3,4,5,6,7,8,9,10,11,12 However, little
    is known about the interplay and possible trade-offs between the different temporal
    and spectral acoustic features during these vocal exchanges.2,13,14 Nightingales
    can flexibly match the pitch of their tonal “whistle songs” in real time during
    counter-singing duels.15,16 Here, we show that the syllable duration of whistle
    playbacks could alter the song responses of wild nightingales, causing their whistle
    duration distribution to shift toward the presented stimulus duration. When exposed
    to whistle playbacks featuring unnatural combinations of pitch and duration, nightingales
    demonstrate a flexible trade-off between pitch matching and temporal imitation,
    yet they are constrained by their vocal repertoire. They selectively adapted their
    vocal responses to approximate these novel stimuli, aligning them with their natural
    whistle repertoire. We developed a computational model of nightingale whistle-matching
    behavior that revealed a hierarchical organization of acoustic feature production.
    During whistle matching, the feature integration process is constrained by the
    duration of syllables, and pitch matching follows within this temporal framework,
    forcing a trade-off between the two features. Our findings reveal a complex interplay
    between the spectral and temporal domains that shapes song-matching behavior.@eng
