To ruffle feathers means to upset or annoy... not sure if this bird is upset or annoyed but I do know that typically I don't see the fluffy feathers underneath the wings of a hummingbird.
Thanks for your comments on my photo from yesterday called "Flight Path". I spent way too much time shooting and editing my three image composite... I literally got sucked into a black hole... I know that many of you can relate to this... and I am still trying to get through the photos from my 6 week camping trip and have to report that we leave soon for another camping trip... this one will be less than a week long trip.
