Those are very nice photographs of the pigeon.
You are right that it is hard to capture good photos of birds and I will even say animals in general.
I had to decrease the exposure time to get the best shots. Some birds do not sit still.
For birds and other animals, I take a lot of photos and only publish the ones that come out. For the dove in my blog post, I had several photos where the dove's movement caused too much blur. I scrapped those photos.
Have a great week!
Steem on,
Mike
