Bird call is made of the typical PB Lark trilling tri-tri-tri followed by a subtle treeeeeee.
观察细节
Bird flying fairly high up (about 50 meters) in a sustained hovering flight. Calls were much like the typical tri-tri-tri/Si-si-si calls with the addition of a faint treeeee following, as noted in the rest of the recording.
