“…Similar results have been obtained from zebra finches (Williams et al, 1992). Nerve cuts in white-crowned sparrows, white-throated sparrows, and java sparrows have not provided evidence for a lateralization of frequency range (Nottebohm and Nottebohm, 1976;Lemon, 1973;Seller, 1979).…”

In brown thrashers (Toxostoma rufum) and grey catbirds (Dumetella carolinensis) neither side of the syrinx has a consistently dominant role in song production. During song, the two sides operate independently, but in close cooperation with each other and with the respiratory muscles which are capable of adjusting expiratory effort to maintain a constant rate of syringeal airflow despite sudden changes in syringeal resistance. Phonation is frequently switched from one side of the syrinx to the other, both between syllables and within a syllable. When both sides of the syrinx produce sound simultaneously, their respective contributions are seldom harmonically related. The resulting "two-voice" syllables sometimes contain difference tones with prominent sinusoidal amplitude modulation (AM). Rarely, both sides simultaneously produce the same sound. In general, however, the frequency range of sound contributed by the right syrinx is higher than that of the left syrinx. The right syrinx is also primarily responsible for producing a rapid cyclical amplitude modulation which is a characteristic feature of some syllables. This kind of AM is generated by either repetitive brief bursts of sound from the right side that modulate the amplitude of a continuous sound arising on the left side or cyclically opening the right syrinx, allowing unmodulated expiratory air to bypass the phonating left side.

Bilateral innervation of syringeal muscles by the hypoglossal nucleus in the jungle crow (Corvus macrorhynchos)

et al. 2009

Bird vocalizations are produced by contractions of syringeal muscles, which are controlled by the hypoglossal nucleus. In oscines, syringeal muscles are controlled by the hypoglossal nucleus ipsilaterally, whereas syringeal innervation is bilateral in non-oscines. We have determined the course of hypoglossal nerves in the jungle crow Corvus macrorhynchos . Our results indicate a cross-over of the hypoglossal nerve from the left side to the right side on the trachea 7 mm rostral to the Musculus sternotrachealis . We also investigated the innervation of the syringeal muscles of jungle crows from the hypoglossal nucleus using the horseradish peroxidase (HRP) method. After HRP was injected into the syringeal muscles on each side, HRP-labeled cells were found bilaterally in the hypoglossal nerve. These results suggest that the syringeal muscles of jungle crows are innervated bilaterally from the hypoglossal nucleus, although these birds are categorized as oscines.

“…Nottebohm (1971) discovered in chaffinches (Frrngillu cordelis) that sectioning the tracheosyringeal branch of the left hypoglossal nerve, and thereby disabling the left sound source, had a drastic effcct on song, whereas sectioning the right nerve to silence the right source had little effect. This "left hypogIossa1 dominance" was also found in white-throated sparrows (Zunotrichia albicullis), canaries, white-crowned sparrows (Zunotrichia leucuphrys) and java sparrows (Padda oryzivora) (Lemon, 1973;Nottebohm and Nottebohm, 1976;Seller. 1979).…”

Lateralization of syringeal function during song production in the canary

The canary (Serinus canaria) vocal organ, the syrinx, has two separate sound sources, one in the cranial end of each bronchus. Previous investigations of whether song syllables are produced unilaterally or bilaterally have provided two contradictory results, as one researcher suggested that almost all syllables are produced by the left side of the syrinx alone, whereas another researcher suggested that both sides contribute similarly to all syllables. Our experiments, which involved unilateral bronchus plugging followed later by denervation of the ipsilateral syringeal muscles, attempted to resolve this disagreement. The males with right bronchus plugs, singing on the left side of the syrinx alone, produced nearly normal songs, whereas the birds with left bronchus plugs, singing on the right side, sang quite poorly. Interpretation of these data is difficult because it is not clear how syringeal function would be affected if the airflow rate through the intact side is increased above normal, nor is it known if the bird can compensate for bronchus occlusion. Nonetheless, we suggest that in male canaries most syllables are normally sung by the left side alone, with some syllables being produced by the right side alone and some being sung by both sides together. Right nerve section had little effect on the right-bronchus-plugged males' ability to sing, but the repertoires of the left-plugged males were altered after left nerve section, indicating the possibility that signals carried by the left nerve exert an influence on the contralateral side.
