Range and Habitat
Nashville Warbler: Breeds from British Columbia and northwestern Montana south to central California and central Idaho; and from Manitoba, Quebec, and Nova Scotia, south to Minnesota, northern West Virginia, and western Maryland. Spends winters south of the U.S.-Mexico border. Preferred habitats include thickets in open mixed forests or brushy borders of swamps.
Although named after Nashville, Tennessee, the Nashville Warbler only visits that area during migration. It was first observed there in 1811 by Alexander Wilson, who named the species.
It sometimes uses porcupine quills as nest material.
The western population was once considered a separate species, called the "Calaveras Warbler."
A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
The Nashville Warbler has a large range, estimated globally at 2,800,000 square kilometers. Native to North and Central America as well as nearby island nations this bird prefers temperate, subtropical, or tropical forest ecosystems. The global population of this bird is estimated at 34,000,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List. For this reason, the current evaluation status of the Nashville Warbler is Least Concern.
