Birdsong that is softer and less well defined than the usual territorial song, sometimes heard only at close quarters as a quiet warbling.
〔鸟〕亚歌
Example sentencesExamples
In the laboratory, hand-reared birds perform subsong throughout their first autumn and winter.
A bird uttering subsong is usually perched low and in an inconspicuous place; the beak may be closed while singing. Subsong is not confined in out-of-season utterances and may readily be heard during the period of full song.
Every time the bird compares its own subsong to the memorized template, the syllables most similar to those present in the template become slightly more probable.
That is, does the bird amplify and modulate the amplitude of subsong primitives, or shorten and protract them, or reorder them, etc.?
