Document Summary
The "wild type" birds = birds that grow up in the wild. Tutors are isolated birds, pupils are the juvenile birds. The researchers wanted to know how birds who in the wild sing a characteristic song learn their songs. Particularly interested in what would happen if they raised birds in isolation, so that they could not learn their songs like they might in the wild. Iso: some syllables are long, while others are stuttered. Birds deprived of song during vocal development develop a less structured. Thursday, may 30, 2019 isolate song with more noisy, broadband notes and high-pitch upsweeps. Pupils imitated all of the tutor syllables but did not invent new syllables. Black lines: pupil songs modify the iso songs to be closer to the wt songs. Purple: density of the range of normality for wt songs. The pupils aren"t changing the tutors" songs randomly: random songs would look different on the graph.
