Sounds and Vocal Behavior

The song of Fulvous-chinned Nunlet is weak series of thin, mewing whistles: wee weep weep weep weep weep..... This song is similar to that of other species of Nonnula, although the song of Fulvous-chinned perhaps is slower than the song of sympatric Rufous-capped Nunnlet (Nonnula ruficapilla) (Lane, in Schulenberg et al. 2010).
