Adult thresholds for 9 individual birds in grey, with the average in black, with respect to stimulus frequency. Thresholds were considered adult by P69 because independent t-tests comparing P69-P74 owl thresholds (n = 5) to owls older than 5 months (n = 4) resulted in no significant difference in threshold for all frequencies tested (p > 0.05), thus thresholds were considered adult by P69.
