Birds of Brooklyn: Yellow-Rumped Warbler
During fall migration, starting around now and through the end of October, huge numbers of yellow-rumped warblers—sometimes hundreds at one site in a single day—will flood our area. This small grayish-brown and yellow bird is among the most common warblers in North America. In the East, it breeds north of New York City in the high elevations of the Adirondacks and in Canada and winters here and elsewhere, especially along the coast. The greatest local concentrations arrive on the barrier beaches of Long Island, but a good number pass through the Garden and Prospect Park—and some will stay for the winter.
As fall progresses, the yellow-rumped warbler transitions to its winter diet. As insects get harder to find, it starts eating berries, especially bayberries, also known as myrtle berries. (Old-time birders refer to this bird as the myrtle warbler.) There is an excellent chance that you’ll see some of these birds at BBG now, especially in the Native Flora Garden, as they feed in the bayberry bushes and other shrubs. The yellow-rump’s plumage is mostly brownish gray with white streaks, and as the name implies, it has a bright yellow rump that makes it fairly easy to spot and identify. Many birders refer to it by the pet name “butter butt.” Be sure to look for this delightful bird this fall!
