These are all great shots, Oca! I hope you don't mind if I make a little suggestion. I noticed that your shots have the subjects right in the middle of the frame. In bird photography the rule of thirds is usually applied, meaning the bird is placed on one third of the frame and the other two thirds is where the bird is facing.
Great set especially the Bee Eater. I agree with Bob's comments re composition - if your Bee Eater was a little lower down (more headroom) and more to the right it would look an even better shot in my opinion.
