After more than a decade of observation and recording, Dr. Julie Elie identified 11 distinct call types used by zebra finches, decoding both their meanings and the individual vocal signatures birds use to recognize each other. Machine learning helped organize the data; crucially, birds confused calls with similar meanings more than similar-sounding ones — showing they respond to content, not just sound.
