This warbler was discovered in 1811 by the noted ornithologist Alexander Wilson, who chose its common name because he first saw it in Tennessee. Its numbers fluctuate greatly from year to year; at times it is very numerous, and a dozen or more may be observed in a single tree, while in other years very few are seen.
5 or 6 brown-spotted white eggs in a nest lined with fine grasses, placed on the ground, and usually well hidden under a shrub or in a moss clump under a tussock.
