Kent Notes From Arkansas

Recorded January 29, 2005



ANALYSIS

Context: Against a background pattering of rain, listen for the "kent"-like calls of an unknown bird species, possibly an Ivory-billed Woodpecker. The recording has two loud songs of a Carolina Wren. The "kent"-like calls are before and after the first Carolina Wren song.

Blue Jays are known to make calls that resemble those of Ivory-billed Woodpecker "kent" calls. These may be imitations of Ivory-billed Woodpeckers or sounds that past generations of Blue Jays heard, imitated, and passed on culturally. It is also possible that the resemblance between the sounds is pure coincidence. The function of the Blue Jay kent calls is unknown.

Recorded March 17, 2005



ANALYSIS

Context: This recording of kent-like calls includes vocalizations of Common Grackles, meaning an alternative source of the kents was identified and is present. While we cannot rule out the plausibility of ivory-bill we also cannot rule out Common Grackle as the source. The recording scores high because the harmonic structure and intervals are in line with what we expect. The notes are also delivered in a series and other sounds were reported on the same day.
