Below you will find links to some of the sounds observed through acoustic monitoring of Northern Saw-whet Owls (NSWO) in the Ozark Highlands and Boston Mountains ecoregions of northern Arkansas. These are not sounds directly from our autonomous recording units (ARUs), but higher quality versions from the Macaulay Library (Cornell Lab of Ornithology). By clicking a link you will be able to hear the sound and view a spectrogram.
Whine vocalization example 1. Commonly heard and probably second most well-known sound to those familiar with NSWO. This link also includes solicitation calls, which were not observed during the study period.
Whine vocalization example 2. A different version of the whine vocalization.
Bark vocalizations example 1. Various bark vocalizations were observed, sometimes given in pairs.
Bark vocalizations example 2. Various bark vocalizations were observed, sometimes given in pairs.
