I also liked the flamingo but the beak and the water almost merge together - this might just be my screen. Did you take any more at different angles? I wonder if you had tilted your camera down a tad whether you might have caught more of the bird's reflection in the water which would have been nice.
Thanks for your comments PhotoTish,I checked back through my flamingo pic's and I dont have any more angles of the flamingo mosty because when I take myboyfriend with me on photograhy trips I never spend long enough with each subject
Number 4 is the winner for me too. The colors work perfectly together especially the orange of the birds chest is complimented nicely by the green of the background. Good capture.
