Sensitive period for song learning outlasts parent-offspring cohesion in wild zebra finches

In wild Australian zebra finches (Taeniopygia castanotis), juvenile-to-parent distance increases after fledging and matches unrelated adults by the second half of the song-learning period.

• Why it matters: Captive studies often assume stable father–offspring tutoring, but natural social dynamics during vocal learning are unclear, risking misinterpretation of functional implications.
• What they did: Zebra finch families were followed across early life in the wild using automated radio-tracking to measure how juvenile distances to parents changed during song learning.
• The result: The dynamic environment suggests juvenile males could learn from many tutors and females may develop broader song preferences, so one-tutor paradigms should be interpreted cautiously.
