“…Previous studies in domesticated canaries reported that stereotypy of syllables showed seasonal changes (Güttinger, 1985;Nottebohm et al, 1986Nottebohm et al, , 1987. At the breeding season, syllables are produced in a strikingly uniform manner, whereas in autumnal songs, the shape of syllables differs within phrases (Fig.…”

“…Song quantification was performed on a spectrogram with special focus on measuring song length, phrase length, and silence between two successive phrases. Because male canaries use a large syllable repertoire, analyses of longduration samples (at least 150 s of song, pauses excluded) of individual songs were required to determine the syllable repertoire (Güttinger et al, 1985). Identifying different syllable types was straightforward: in spectrograms, syllables differ in shapes and in duration.…”

To what extent seasonal factors modify the neuronal functional properties within the nuclei of the avian song system remains an open question. In adult songbirds, neurons of the song premotor nucleus HVC (used as a proper name) exhibit selective responses for the bird's own song (BOS). Here we examine whether, outside the breeding season, when songs are less stereotyped, HVC neurons of male canaries still respond selectively to the BOS produced during this period. In an initial experiment, single-unit recordings (n ϭ 114) revealed that the neuronal selectivity for the current BOS was attenuated in males exposed to a short-day photoperiod (typical of the nonbreeding season) compared with that found in males exposed to a long-day photoperiod. In long-day conditions, 35% of the cells responded to the BOS, whereas only 12% did in short-day conditions; there were four times more selective cells (d Ͼ 1) in long-day than in short-day conditions.To determine whether these effects were the consequence of differences in acoustic features between breeding and nonbreeding songs, neurons (n ϭ 72) recorded in short-day conditions were tested with both a short-day BOS and a long-day BOS. A low percentage of neurons exhibited responses to short-day or to long-day BOS (11% for each song). Responses of putative interneurons (spike duration Ͻ0.4 ms) and of putative relay cells were similarly attenuated by the short-day conditions. These results strongly suggest that, in canary, rather than being a fixed property, the selectivity for the BOS moves along a continuum and peaks when the day length mimics the breeding conditions.

“…As Serinus spp. songs do not generally have predetermined ending syllables (e.g., Güttinger 1985;Mota and Cardoso 2001), this produces syntactically normal songs. Song length of experiment 1 stimuli averaged 5.72 s (±0.99 SD), which corresponds to relatively long serin songs (Mota and Cardoso 2001).…”

We tested if male or female behavior towards manipulated song indicates intra-or inter-sexual selection of two characteristics of serin song that are extreme and evolutionarily derived in this species: high frequency and fast syllable rate. In a first experiment, we monitored vocal responses and attendance to song playbacks. Female behavior indicated a preference for high-frequency song and suggested an aggressive function for fast syllable rates, as fast songs inhibited vocal response. Males did not show discrimination of frequency or syllable rate with this experimental design. The second experiment used a simple approach/no approach design, and in this experiment, males showed stronger discrimination between stimuli than did females. Therefore, sex differences in discrimination appear not to result from differences in perceptual abilities but from differences in the context of stimulus presentation. The second experiment also supported a role of song frequency in female choice, as the effect of frequency was limited to females: males did not respond differently to song frequency and approached high-frequency songs less than females did. Results of this experiment also supported an aggressive function for fast syllable rates, as the effect of fast songs did extend to male behavior. Taken together, our results indicate that the high frequency and fast syllable rate of serin song cannot result from a single selection process: while high frequency may have evolved by inter-sexual selection, syllable rate provokes a pattern of response that is more consistent with intra-sexual selection.

“…Canaries have been a favorite species of aviculturists for some time, and were bred for their plumage and distinctive songs (Guttinger, 1985;Stresemann, 1923). One strain, the Belgian Waterslager canary, hereafter referred to as 'Waterslager', is particularly noted for its loud, clear song.…”

Recent reports of elevated auditory thresholds in canaries of the Belgian Waterslager strain have shown thai this strain has an inherited auditory deficit in which absolute auditory thresholds at high frequencies (i.e. above 2.(1 kHz) are as much as 41) dB less sensitive than the thresholds of mixed-breed canaries and those of other strains. The measurement of CAP audiograms showed that the hearing deficit is already present at the level of the auditory nerve (Gleich and Dooling, 1992). Here we show gross abnormalities in the anatomy of the basilar papilla of Belgian Waterslager canaries at the level of the hair cell. The extent of these abnormalities was correlated with the amount of hearing deficit as measured behaviorally.
