Yellow-rumped warblers are found throughout North America and winter down into Central America and the Caribbean islands. Originally they were listed as two species; Myrtle and Audubon’s. In 1973. The checklist committee of the American ornithologist union birds. The Eastern Myrtle Warbler in the Western Audubon’s Warbler into a single species now called Yellow-rumped Warbler. It now looks because of DNA studies that the Yellow-rumped Warbler will again split into two separate species. Time will tell.
Yellow-rumped Warblers are among the earliest migrants in the spring and the latest migrants in the fall. In the spring because these warblers have bright colors they are very easy to identify, especially because of the yellow rump. In the autumn, the colors a dull but usually the yellow rump is visible.
The other day I was down at Tamarac Park and while checking out the water level in the marsh, which is slowly returning to normal, I noticed birds flitting around and acting like flycatchers picking insects out of the air. I did not see any yellow rumps, however looking at my images on the computer, they show the characteristics of the eastern subspecies the Myrtle Warbler.
So while you are out, keep an eye out for yellow-rumped warblers because there is always the chance that the western subspecies will show up here in the East.
