While sitting on the ground, these buntings all looked pretty much the same. But when they lifted off, I noticed significant differences in the wing pattern. Of these three birds, each one has a different amount of white on the wings, from more white to less white. Why? I did a lot of reading and picture review, and I couldn't find a single web site that showed the differences I see here. Text reported that the male has more white than the female and juveniles. Applying that info to these pictures, it suggests the bird to the farthest left is a male. Is the middle bird a female with the bird on the right being an immature? If any one can confirm this, please leave a comment.
