![]() ![]() We have observed them here at GCBO headquarters at our feeders, while surveying for Loggerhead Shrikes in grassy and shrubby habitat, and even in the salt cedar patches along Matagorda Beach. They can be found in a variety of habitats such as agriculture fields, residential areas, marshes, shrubs, forests, and even beaches. This is why people often refer to them as “butter butts.” Both the “Audubon’s” and “Myrtle” species have the distinct yellow rump patch.ĭuring the winter they migrate and feed in large flocks. Their most distinguished feature is of course the bright yellow patch on their rump. They also have small pointed black beaks and short black legs. Their head is gray with a faint white eye stripe or eyebrow and a white eye ring. They have white bellies with gray streaks and yellow patches on both sides. We see them mainly in their wintering plumage when their bodies are brownish gray above with white wing bars and white below including the throat. Like many birds, its plumage changes with season. It can be found in the Southern United States to as far South as Mexico and the Caribbean. It is considered to be the most common wintering warbler in North America. We typically see the “Myrtle” species here in Texas. There are two subspecies, the “Audubon’s” and the “Myrtle”. Yellow-rumped Warblers are small songbirds that are only here during the winter months. Along with these species, another wintering species we come across is the Yellow-rumped Warbler. Our target species are Piping Plover, Snowy Plover, Red Knot, Black Skimmer, and American Oystercatcher. We monitor Matagorda Beach, Bryan Beach, Quintana Beach, Surfside Beach, and Follet’s Island until the end of March. More about Yellow-rumped Warbler at All About Birds.During the winter, Gulf Coast Bird Observatory is surveying for non-breeding shorebirds along the Upper Texas Coast. Yellow-rumped Warblers are tolerant of disturbed habitats eastern populations have been stable or increasing, whereas western populations have shown a steady decline since 1970. and in the highlands of central and western Mexico. and southwestern Canada and winters in the southwestern U.S. ![]() The western population (“Audubon’s Warbler”) breeds in coniferous forests of the western U.S. ![]() The northern and eastern population (“Myrtle Warbler”) breeds throughout the boreal forest of Alaska and Canada, migrating east and south to spend the winter primarily in the southeastern U.S.-small numbers reach eastern Mexico and the Caribbean, especially during cold northern winters. The Yellow-rumped Warbler is one of the most abundant birds in North America, connecting almost every part of Canada, the U.S., and Mexico during its annual cycle. About Yellow-rumped Warbler Abundance and Distribution As more and more eBird data become available, the accuracy of these predictive models will improve. Please note that because these maps represent models of predicted abundance, they are shown to illustrate broad patterns of connectivity across regions and are not intended to accurately depict local distributions in any given week. The data used to generate this animation were produced using a statistical model to predict the relative abundance of the population at specific times and locations by relating observations of birds from eBird to local environmental features derived from NASA remote sensing data. ![]() The brighter the color, the higher the expected count of the species on a standardized eBird count. The animation illustrates the migratory movements of each species as its populations travel across North America. The animated map shows the Yellow-rumped Warbler’s predicted distribution and relative abundance across all 52 weeks of the year. Brighter colors indicate higher relative abundance. ![]()
