Hi Yisehaq,
The shot is reasonably well exposed and focused, but the main problem is the composition and content.
To do the Pelican's justce, I think you generally would want to have no more than 3 in shot and then, if more than one, you want them arranged better - all those facing away or part cropped are not contributing to a good image.
Portraits, even of birds, really need to include the eyes (and face), here we have 6 birds and only one face.
My advice would be to take a little more time; wait until you have a fewer, or just one, on its own and take a picture of that when it is facing the camera.
Here are some of examples;
If you want to shoot larger groups, it helps if they're all doing something together, rather than ambling around randomly each doing their own thing.

Hope that helps,
Thanks so much Dave. That was a lot of help. I tend to concentrate at times on one element as you mentioned and forget other points.
That is one of the hardest things - making sure that there are no unwanted elements in the viewfinder. I forget to do it all the time.....so my deletion rate is high.
