Two Peregrines, one HY bird perched on a power pole, one adult flying around the pole in circles, vocalizing. From what I could tell the vocalizations were coming just from the flying adult, though it was hard to be certain. Certainly the ca-check, ca-check, ca-check calls were the circling adult.
观察细节
One HY bird perched on a power pole, one adult flying in circles around the pole, vocalizing. The ca-cheek, ca-cheek, ca-cheek calls were given by the adult when furthest away from the HY bird, while the long screeches were generally given as the adult passed over the perched HY bird.
