单词	subsong
释义	subsong /ˈsʌbsɒŋ / noun [mass noun] Ornithology Birdsong that is softer and less well defined than the usual territorial song, sometimes heard only at close quarters as a quiet warbling.In the laboratory, hand-reared birds perform subsong throughout their first autumn and winter.... 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.?
