Примечания
A recording of the periodic calls of a flock of 18 Sandhill Cranes, as they were close to completing their five minute spiralling ascent up a thermal to a higher altitude. Shortly afterwards, they carried on with their migratory flight to the WSW.
Подробности наблюдения
Flew from NE, then when almost directly overhead, they circled for about five minutes, seemingly having caught an upwards thermal, gradually climbing while circling/spiralling until they had more than doubled or possibly even tripled their altitude before continuing WSW.
