This bird is known for its distinctive yellow rump patch, which is a bright yellow color and is easily visible when the bird is in flight. The Yellow-rumped Warbler is a migratory bird, and it spends its summers in the northern parts of North America and winters in the southern parts of the continent.
The Yellow-rumped Warbler is a small bird, measuring about 5 to 6 inches in length and weighing around 0.4 to 0.5 ounces. The male and female birds have similar plumage, with the male having slightly brighter colors. The bird’s upperparts are grayish-blue, and it has a white belly.
