“…There are five subspecies of Rufous-andwhite Wrens found along the Pacific coast of Central America-three found from Mexico to Panama (T. r. transfinis, T. r. rufalbus and T. r. castanonotus) and two in northern South America, in Colombia and Venezuela (T. r. cumanensis and T. r. minlosi ;Brewer 2001). The songs and vocal behavior of both Rufous-andwhite Wrens (T. r. castanonotus; Mennill and Vehrencamp 2005) and Niceforo's Wrens (Valderrama et al 2008) have only recently been described in detail.…”

“…We measured songs recorded from 19 male Niceforo's Wrens from the Chicamocha river valley in the Eastern Andes of Colombia, the only area where Niceforo's Wrens persist (Valderrama et al 2007). We recorded 1282 songs from eight males between 29 July and 28 December 2004 and 3677 songs from 11 males between 19 July and 9 August 2006 (175 distinct song types from 19 different males; song types defined following Valderrama et al 2008). Nine birds in the study population were individually marked with distinctive color bands, and the remaining birds were easily distinguished by territory location.…”

“…Recordings were collected in different areas in 2004 and 2006. We estimate that the 19 recorded birds constitute approximately half of all extant male Niceforo's Wrens (BirdLife International 2000;Valderrama et al 2008).…”

“…We based analyses on previous vocal studies of both species (Rufous-and-white Wrens: Mennill and Vehrencamp 2005; Niceforo's Wrens: Valderrama et al 2008). In both Rufous-andwhite and Niceforo's Wrens, males and females sing solo songs, and breeding partners combine their solo songs to produce coordinated duets.…”

“…We used Syrinx-PC (J. Burt, Seattle, Washington) to generate sound spectrograms and measure fine structural features of songs. Song types were identified following Mennill and Vehrencamp (2005) and Valderrama et al (2008). The highest quality recording of each song type was selected for each individual.…”

Does syntax contribute to the function of duets in a parrot, Amazona auropalliata?

Complex acoustic signals in many animal species are characterized by a syntax that governs how different notes are combined, but the importance of syntax to the communicative function of signals is not well understood. Mated pairs of yellow-naped amazons, Amazona auropalliata, produce coordinated vocal duets that are used for territory maintenance and defense. These duets follow rules that specify the ordering of notes within duets, such as a strict alternation of sex-specific notes and a defined progression of note types through each duet. These syntactical rules may function to define sex-specific roles, improve coordination, and allow individuals to combine calls into meaningful sequences. As a first step toward understanding the functional significance of syntax, we conducted two separate audio playback experiments in which we presented nesting pairs with normal duets and duets with broken syntax (i.e., one of the syntactic rules was broken). In Experiment One, we reversed the order of female and male notes within note pairs while retaining the typical progression of note types through a duet. In Experiment Two we reversed the order of note types across a whole duet while retaining the typical female-male ordering within note pairs. We hypothesized that duets with broken syntax would be less-effective signals than duets with normal syntax and predicted that pairs would respond less to broken syntax than to normal duets. Contrary to predictions, we did not observe differences in response between treatments for any variables except latency to approach the speaker. After we combined data across experiments post hoc, we observed longer latencies to approach the speakers after playbacks of broken syntax duets, suggesting that pairs could differentiate between playbacks. These responses suggest that breaking one rule of duet syntax at a time does not result in detectable loss of signal efficacy in the context of territorial intrusions.
