I originally heard this owl call about 17:00 on 24 March. This environment would likely be hostile to a predatory Barred Owl, which prefers old-growth deciduous forests. The location bordered a saltmarsh with several dead trees in which woodpeckers had bored cavities. This bird too is a probable transient which was unsuccessful and has since moved on. (There are transient wintering birds here, infrequently caught in trail camera images, but otherwise silent.) This recording is the trill, or bounce song, indicative of an owl which had likely found an acceptable nest/territory and was searching for a mate. Development has played a role but predation by Barred Owls is the likely primary cause. This species is largely extirpated from this location and and is now scarce in Chatham County, Georgia.
