Last summer I have visited Hungary with target to see Great Bustard which is very rare spice. From the build small hide i was lucky enough to get pictures of whole series displaying bustard. Whites are visible for far distance in the bush which the main purpose - to attract female.

Great behavior shot, he really looks impressive. :) Maybe you could give it a bit more room left and right. My only nit are the OOF blades of grass in the foreground. Asking to mow first is maybe a bit much expected, though. :)
Last year I was in Hungary and this was one of our targetbirds to photograph. Fortunatly we saw it, but unfortunatly we could not photograph them. You did very well. Very nice image.
Excellent display pose of this beautiful bird. I like the oof grass in the foreground and your low perspective. The head angle is great, even in his display posture, and the eye is clearly visible. Good exposure control. I also might consider removing the blue sky at the top of the frame. Lovely!
