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.

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.
