One of the earliest warblers to migrate in spring, I don’t recall seeing a Yellow-rumped Warbler this early in the season. This little fellow was finding insects, seeds, and berries in the snow covered scrub line along the shore.
Yellow-rumped warblers have a highly varied diet, which allows them to winter further north than any other warbler, including as far north as Nova Scotia. Their diet consists of every imaginable insect, along with seeds, fruits, and berries including bayberry, myrtle, juniper, poison ivy, Virginia creeper, dogwood, grapes, poison ivy, grass and goldenrod seeds.
Until 1973, Yellow-rumped Warblers were listed as two different species, the western Audubon’s Warbler and the eastern Myrtle Warbler. Both names are much lovelier than the undignified ‘yellow-rumped,’ don’t you think? More research and DNA studies has revealed they are two distinct species. Let’s hope the names Audubon’s and Myrtle will be reinstated 🙂
Perhaps this young warbler has been here all winter. Please write and let me know fellow bird lovers, are you too seeing Yellow-rumped Warblers?
