The background is perfect! What do you mean less busy? You’ve made an excellent photo of one of these funny fuzzballs.
Don’t get me wrong, I’m very fond of this picture (I wouldn’t have posted it otherwise), but the couple of thin branches directly behind the bird break its silouhette a bit. The rest is 100% to my liking.
That’s just nature. You can’t force that birb to sit higher on the branche. So I wouldn’t worry about it,
It always amazes me that one of the most beautiful birds of them all - from anywhere in the world, even the tropics - is a common sight in the backyards of dreary northern Europe.
This is one of the reasons I love wildlife photography: some of these creatures are so tiny and fast, that appreciating their colors and patterns with the naked eye is really challenging. With a big telephoto and if you get close enough though, you can pick out all the tiny details of these awesome chirping fluffy things :)
Goodness they’re so pretty!
The branches are perfect. They aren’t too busy and actually frame the picture well so the bird is the focus.
