Détails de l'observation
Attached is a recording of a chatter I heard. The chatter is some small shorebird. There is a slight descending of frequency in the chatter, with some modulation. I have attached the spectrogram of my nocturnal flight call (left) versus a verified Semipalmated Sandpiper (right). Frequency and rate of decrease in frequency of chatter matches that of Semipalmated. I don't think any of the other small sandpipers who this low frequency chatter or the descending chatter.
