Most warblers pass briefly through my area when they are migrating in the spring and in the fall, but Yellow-rumped Warblers (Setophaga coronata) stay with us for a good part of the colder season. This past Thursday I spotted quite a large number of Yellow-rumped Warblers as I wandered the trails at Occoquan Bay National Wildlife Refuge.
In the first photo, you can see a portion of the yellow patch that is responsible for the name of this species. Most of the time I see only the smaller yellow patches on their sides, because they tend to perch high above me and I am often shooting at an upwards angle.
I am amazed by the light weight of Yellow-rumped Warblers and their ability to perch on incredibly slender branches, as you can see in the second image. According to the Cornell Lab of Ornithology, these little birds weigh only 0.4-0.5 ounces (12-13 g).
In the final photo, the warbler is poised to move on to its next perch. Yellow-rumped Warblers are not quite as hyperactive as some other species that I see at this time of the year, like Ruby-crowned and Golden-crowned Kinglets, but they move around a lot as they forage for food.
