观察细节
Heard only, was flying overhead in a bout a 50-yard radius probably 30-50 yards up. Kept repeating the same three quick note phrase in regular intervals, all notes sounding to be of same pitch. Recording attached. Almost cricket-like sound, a bit higher (Hz) than most recordings I listened to on Xeno-canto of Lapland Longspur, also not like the trill which most of those recordings had. Closest call I have found in Xeno-canto is a nocturnal flight call of Snow Bunting but an expert confirmed this as a Lapland Longspur. Recording attached.
