Developmental milestone – our partners at Cornell Lab of Ornithology just posted this video and provided the following explanation of threat displays as our older owlet demonstrates!
In this clip we see the older owlet bill-clapping at some rather noisy American Crows. In both adults and older young, at least 3 forms of threat displays grade into one another. In the clip we see a mild threat-display. Mild threat displays consist of agitated bill-clapping, hissing, occasional low, drawn-out screams, and other guttural noises. A behavior we have have seen from Mom and not the owlets yet is a second level threat consisting of fully spread wings arching in a ‘wall’ towards an intruder, this posture has also been accompanied by bill-clapping and hissing.
We have not yet seen a third threat level consisting of spread wings, bill-clapping, hissing, high pitched screams for a long duration, feet are also poised to strike.
