Butterbutt news......Yellow rumped Warbler Sycamore Canyon California 036
Butter-butts fill the air. They are so common right now why strain myself to nab a photo? Audubon or Myrtle? At one time they were considered two distinct species then lumped together and might be split again.
How far we have come from the 1800s studies of an Agustinian friar concerning peas.
"One of North America’s most beloved songbirds – the yellow-rumped warbler – may be at least three separate species, says a study published Aug. 24 in The Auk. This discovery contradicts how ornithologists classified the bird for almost five decades.
The new work brings a wealth of genetic evidence to bear on the question and for the first time identifies where in the warblers’ DNA species have diverged from each other. That opens the door to discovering what’s responsible for differences in how the birds look, sound and act, said lead author David Toews, a postdoctoral researcher at the Cornell Lab of Ornithology.
“The yellow-rumped warbler – this species that’s familiar to just about every birder in North America – has four distinct forms, and now we have quite compelling evidence that three of them are full species,” said Toews, who began the work while he was a doctoral student with study co-author Darren Irwin at University of British Columbia.
