Spring: Common Yellowthroats nest in Northern Virginia, but not at Monticello Park. They prefer habitats in marshes and near rivers, but a good number visit Monticello each spring. The best time to see them is during the second week in May.
Fall: Common Yellowthroats begin to migrate south in August. They are most frequently seen at Monticello from the second week in September through the end of the month.
Where to See Them in the Park
Common Yellowthroats skulk low in the bushes, but not so deeply that you cannot find them. They are quite vocal, and they often go into the stream to bathe and drink.
The male Common Yellowthroat is easy to identify because of his black "bandit's mask", with a thick gray stripe arcing over it. As the name would indicate, he has a yellow throat. His back is olive, and he has yellow edges on his wing feathers and tail.
The males will sometimes sing from the end of an exposed branch.
Second-year males have a trace of a black mask with a gray stripe over it, but these fieldmarks are not well defined.
Female Common Yellowthroats can create significant identification challenges. They lack the black mask, and they have a broken white eyering. The yellow feather edges on the tail and wings, which did not seem prominent on the male, become an important fieldmark when trying to identify a female. The yellow undertail feathers also can be helpful.
Fall: Fall adult male yellowthroats have brown on their flanks, and first-fall males have a trace of a mask. Fall adult females resemble spring adult females, and first-fall females have more brown and less yellow than a spring adult female.
Common Yellowthroats sing a broad range of songs. One of the best known is witchety-witchety-witchety. The yellowthroat also utters a dry, raspy call note.

The Common Yellowthroat used to be called the Black-masked Ground Warbler. A yellowthroat was one of the first specimens from the New World to be catalogued by Carl Linnaeus, who formalized the system of binomial nomenclature for life forms. The specimen came from Maryland, which is why the species used to be called the Maryland Yellowthroat. The newsletter of the Maryland Ornithological Society is called the Maryland Yellowthroat. There are six other species of yellowthroats in the same genus, but none regularly occur in the United States.
