Another thing that makes Short-eared Owls so fascinating to observe is their vocalizations. These birds make sounds in a variety of ways. First, is their primary “hoot”. I have never heard this in person because this is primarily used by males in advertising for mates and establishing territories in the nesting season. You can, however, hear the barks and screams given by both males and females on their wintering grounds. The screams seem to be primarily given while in flight and the barks can be given in flight or while perched. I do not know the purposes of these two call types but will put this on my list to research. Another sound these birds deliver is the wing clap. This seems to be primarily used by males in their courtship flights and I have not observed this yet in Missouri.
