Vocalizations

Call or day song is a low-pitched whistle. This vocalization has been described as "a softly whistled, drawn-out weeeaaaweee, sometimes followed by brief low note, has wheezy quality", and as "a low, rising-falling or slightly quavering, mewing whistle: meeooo, or with terminal emphasis: meeooo'OO . The dawn song is similar to "an alternating mournful toooo, reer; wheeee-oooh, the last two notes being like the normal daytime song" or "a low mewing whistle ending with a higher hiccup: meeoooOOoo'WEEpur!"
