Abstract: Lay Summary This is the first study to survey vocalizations from shorebird eggs in the field and to assess potential costs of vocalization. Embryonic vocalizations only occurred during the 4 days before hatching. Once detected, embryonic vocalizations increased in rate and frequency with age. Acoustic cues did not heighten the risk of egg depredation, suggesting that this potential cost of vocalization may not apply.
