Sounds and Vocal Behavior

The song of Streak-headed Woodcreeper is a trill, described variously as "a simple, descending, clear trill, soft and melodious" (Stiles and Skutch 1989); as "a clear musical descending trill that lasts 1.5-3 seconds" (Ridgely and Greenfield 2001b); as "a high-pitched, thin, flat trill, p'e'e'e'e'e'e'e'eeeaaa, rapid and descending throughout, ca 2-2.5 sec." (Hilty 2003); and as 'a loud, ringing, rapid, descending series of puttering notes: pee'i'i'i'i'i'i'i'i'i'i'i'i'i'i'i'i'ew" (Lane, in Schulenberg et al. 2010).

The frequency of singing by Streak-headed Woodcreeper increases slightly before the breeding season (Lefebvre et al. 1992).

Calls of Streak-headed Woodcreeper include "a harsher, more rattling, shorter trill" (Stiles and Skutch 1989) and "a soft plaintive pyuu" or "a loud, rapidly quavering, descending pee'i'i'u" (Lane, in Schulenberg et al. 2010).

Across all of the woodcreepers, acoustic characters such as tempo and frequency are correlated with beak structure, with larger-billed species tending to have slower songs with narrower frequency bandwidths. This implies that selection influencing bill morphology also affects woodcreeper song (Derryberry 2012).

Additional audio recordings of vocalizations of Streak-headed Woodcreeper can be heard at Macaulay Library, at xeno-canto, and at Internet Bird Collection.
