We don't often see warblers in our feeder area , so it was a very pleasant surprise to see this little Yellow Rumped visitor flitting about our trees a few days ago. At first I was confused about its id, but upon downloading the pictures I saw an unmistakable yellow showing under its folded wings on its lower back!
Ah ha! it has a yellow rump!
A double check in a bird field guide and I was confident in identifying this sweet bird as a Yellow -rumped Warbler!
