Monitoring the courtship flight trajectory of Latham's snipe (Gallinago hardwickii) using microphone arrays

This study is the first to quantitatively measure the courtship display flights of Latham's snipe (Gallinago hardwickii), which is a “near threatened” species as of 2022 (IUCN red list of threatened species). By using a 16‐channel microphone array and 8‐channel microphone arrays, we localized t...

description This study is the first to quantitatively measure the courtship display flights of Latham's snipe (Gallinago hardwickii), which is a “near threatened” species as of 2022 (IUCN red list of threatened species). By using a 16‐channel microphone array and 8‐channel microphone arrays, we localized the fine‐scale movements of courtship flights of one male performing at high altitude and high speed, and we estimated the direction from which each sound arrived using robot audition. Preliminary analyses of the azimuthal and elevation angles of the courtship flights partially revealed a fine‐scale flight trajectory. First, a male Latham's snipe gradually gained altitude while vocalizing sharp and harsh repeating calls, until it reached the flight peak altitude, then dove down while producing winnowing sound to the ground along the wetland zones without tall vegetation. This observation method is methodologically useful to establish a better understanding of Latham's snipe courtship flight site selection. Furthermore, this method can be extended to investigate other rare nocturnal or crepuscular birds that are too timid to risk ringing or tagging.
