Nature, 2009
Zebra finches raised in isolation, which sing abnormal song, were used as tutors for a second generation, whose birds tutored a third, and so on. Each generation’s song was measured against wild-type song, in both a one-to-one tutoring design and a small breeding colony founded entirely by isolates.
- Studied in
- Taeniopygia guttata
- Sample size
- isolate-founded lineages followed over several generations
Song moved towards wild-type structure at every generation, and within three to four generations the colony was singing song statistically indistinguishable from wild-type on the measured features.
What it means
The authors' reading, and ours. Where they differ, that difference is the point.
How the authors put it
The wild-type song is an attractor: learners systematically fail to copy certain features of an abnormal model and their errors are biased in a consistent direction, so a culture reconstructs itself from a degraded start.
How NatureHQ reads it
One of the most quietly remarkable results in the whole of animal behaviour, and it settles an argument the isolation experiments could not. An isolate’s song is abnormal, so the naive reading is that culture is doing all the work; this shows that the copying errors are not random. They are biased towards a particular form, and running that bias for a few generations reassembles the species song out of nothing. Culture and biology are not competing explanations here — the culture is the vehicle and the bias is the destination.
- A laboratory species with an unusually stereotyped song, in an environment with no predation, no competition and no female choice.
- "Statistically indistinguishable on measured features" is not identity; the features chosen bound the claim.
- Whether the same reconstruction happens in open-ended learners, or in species with large repertoires, is untested.
Starting a colony with birds that sing the wrong song
If a population’s song is destroyed, does it drift away for good, or does it come back?
What this study is used for on NatureHQ
One study can inform several subjects. Here is everywhere this one is cited.
How birds learn to sing
A songbird raised where it can hear no other bird still sings — but it sings something structurally wrong, because the specific pattern has to be learned from an adult.
How birds learn to sing
A young bird in a wood full of singers copies almost none of them: it arrives with a bias about which sounds are worth memorising.
Birdsong
The strongest case for culture in any animal is not a primate or a whale. It is a sparrow.
