Vocalizations

Development

Young nestlings produce low, soft peeps (pipsee) while in the nest, especially in response to the arrival of parents or other disturbance (Brown and Amadon 1968, Preston 2000). Between leaving the nest and attaining independence, juveniles utter loud, persistent hunger calls (klee-uk) in rapid sequence. These calls are accompanied by rhythmic wing fluttering upon approach by parents (Fitch et al. 1946b).

Array of Sounds

Among adults, the most familiar vocalization is a 2–3 s hoarse scream, kee-eeee-arrr (Figure 4) , that rises gradually then descends near the end. Cry often signals irritation or a defensive response when its territory is entered by an intruder or perceived threat (Brown and Amadon 1968). Duration, pitch, and general quality of the scream vary greatly, presumably with age, gender, and circumstance. Often described as having a “steam-whistle” quality, (e.g. Brown and Amadon 1968). Usually produced by soaring birds, it is also uttered from a perch or during active flight. Given frequently in sequence during territorial disputes (Fitch et al. 1946b, Brown and Amadon 1968) and occasionally in response to human intrusion. Nestlings utter a softer version of the scream. During courtship flight, a sharp, shrill chwirk is produced by one or both mates (Figure 4). Several of these chirps are uttered at intervals of about a second (Fitch et al. 1946b). Mates also utter a low, nasal gannk when near one another.

Places of Vocalizing

Vocalizations occur most often near nest during breeding season (biased by prevalence of studies associated with breeding) and during aerial territorial displays (Bent 1937b, Palmer 1988f, Preston 2000).
